How about Breitling Superocean Heritage Ⅱ 42/46 with a modified Tudor Caliber MT5612?

At 2017’s Baselworld Watch Fair, you must be impressed by the fact that Breitling and Tudor joined hands. Breitling supplied Caliber B01 for Tudor. In exchange, Tudor also provided Breitling with Caliber MT5612. It is generally known that there are such disparities between their brand positionings, so the skip-level cooperation confused me. In fact, it represents that Breitling won’t research and develop its own basic movements, and neither will Tudor. The advantage to this is that the cooperation can reduce the development cost and meet their product line. In short, it really kills two birds with one stone. It seems that a number of experts mind it. For most consumers, they are willing to spend money on good watches as long as they are of high quality, good look and good price.

Superocean Heritage Ⅰ vs  Ⅱ

Superocean Heritage II  42  vs  46

Those who are familiar with Breitling style and brand positioning known that Breitling watches are full of hard lines and cool, and so is Breitling Colt 36 female watch, so it isn’t appropriate for fair ladies. There are different kinds of men’s watches. Comparing with Breitling Superocean series-diving tool watches, Breitling Superocean Heritage series stands out its classic elements. Generally speaking, the logo of Breitling Tool Watch is a capital B with a pair of wings, such as Navitimer series, Chronoliner series, Chronomat series, Avenger series and so on, while Superocean Heritage has a stereo gold B logo, simple but luxury. Breitling Superocean Heritage Ⅱ is available in two sizes-42 mm /46 mm. They inherited the main features of Superocean Heritage 42/46, but minor changes exist. For the hour hand, Superocean Heritage 42/46 has an arrow hand, while Superocean Heritage Ⅱ has a flat arrow within a slim line. The pencil-shaped minute hand was transformed into the sword-shaped one or the rhombic one. It’s clear that the date aperture was moved from three O’clock to six O’clock. With the ceramic bezel, Superocean Heritage Ⅱ is equipped with a Caliber B20, a modified Tudor Caliber MT5612. Its power reserve extends up to 70 hours. Comparing with Superocean Heritage watch with a Caliber B17-a modified ETA-2824-2, the latest generation has higher performance.

Tudor  MT5612  vs  Breitling  B20

Available in 4 different dials and five kinds of straps, so it caused price variance from $ 3,389 to $ 4,050. Tudor Heritage Black Bay watch is equipped with Breitling Caliber B01. Breitling watch has discount, so its final price is close to Tudor Heritage Black Bay watch’s. Viewing from the brand positioning and polished B20, Breitling Superocean Heritage Ⅱ 42/46 is worth collecting. Besides, Breitling also supplies special tailor-made service. Your name can be printed on the watch, or you can assemble a characteristic watch according to your needs. In a word, I prefer Breitling Superocean Heritage Ⅱ 42/46 watch to Tudor Heritage Black Bay watch.

Silicon/Gold Gears Create New Possibilities!

At Baselworld 2016-Watch and Jewel Show, Breitling, Piaget and Land & Heyne all launched new gears made of silicon or gold, in order to enhance the performance of the movement. What they have in common is the application of DRIE (Deep Reactive Ion Etching) or UV LIGA (Lithographie & Galvanoformung & Abformung) techniques. Breitling selected silicon to fabricate gears so as to reduce energy loss, while Piaget and Lang & Heyne
developed gold gears, not worse than other two brands. Three watch brands created new possibilities in the atomic domain.                                                    Breitling Superocean Heritage Chronoworks® Limited Edition Watch


Silicon gears aim to improve the performance of Breitling B01 self-winding mechanical chronograph movement, which would later became Breitling Caliber B01 Chronoworks®. In fact, a watch movement is in stopped state in 95% of the time, but it loses the energy every time when we restart it. In order to avoid lower the loss, Breitling adopted silicon to produce three of the most important wheels: center wheel, third wheel and fourth wheel since silion is only half as weighty as ordinary material. These gears are made by DRIE (deep reaction ion etching) process, which makes the whole structure more stable. Most of energy losses occurs in motion of the escapement system, so escape system is another part need to be improved. Silicon lever and escape wheel can reduce the weight of Swiss lever escapement and the inertia in operation effectively. Optimized escape wheel makes the effective utilization rate of barrel kinetic energy increase by 42%.

Breitling Caliber B01 Chronoworks®
Silicon gears

Silicon gears supplied by Siga-Tech Company was connected to untreated steel axle by Breitling self-developed package technique. The combination of steel and silicon means teeth must be shaped precisely in case hard silicon stab into the metal. The application of silicon gears created an industry precedent. Silicon gears and other four innovations (ceramic baseplate and bridges, silicon escape system, variable-inertia balance wheel and seconds pinion with elastic toothing) make power reserve increase by 45%, from 70 hours to 100 hours. Breitling Caliber B01 Chronoworks® movement was passed successfully by Swiss Official Chronometer Control.

Lang & Heyne gold gears

Piaget Calibre 700P

Patek Philippe, Kari Voutilainen and De Bethune have used gold gears in specific movements. Many watch brands laid gold gears aside since the force of machine operation would cause bending deformation of gold after gold is in laser hardened process. 24 K gold gears are made with UV LIGA developed by Mimo-Tec Company. Gold gears (Vickers hardness: 260) is better resistance than brass gears (Vickers hardness: 185), helping improve the performance of the movement. For Piaget, The place of innovation is that Piaget Calibre 700P (Vickers hardness: 220) with pure gold gears and quartz thruster. Piaget Emperador Coussin XL 700P watch launched at Basel world 2016 Fair.

In top watchmaking, small machinery parts also have innovation needs and space. Watch brands improve constantly the performance of watches and movements to prove themselves and create more wonders.

Breitling self-made movements with high efficiency, reliability and high accuracy (B)

Facing the competetive watchmaking market, Breitling has just been proving itself by self-developed movements and products with high performance and good quality. I have introduced Breitling Chronomat 01, Cal. B04, Cal. B05 and Cal. B35 in the previous post. The following content is about the introduction of Breitling other movements.

Breitling B06
Breitling B06 was equipped with 30-second chronograph from 1926’s patent of innovation. It takes only 30 seconds for central timming hand to go around the dial. The timing accuracy extends to 1/8 second. Intermediate stop clock drive chain and chronometer stop clock drive chain were replaced by a part with the best deceleration function. Only Breitling For Bentley B06 watch is equipped with Caliber Breitling B06. Besides, Bentley B06 watch has another global exclusive patented technology-Variable speedometer which can figure out average speed by rotating the bezel freedom from time, distance or speed, a good example of Breitling for Bentley watches. 

Breitling B02/B12
Caliber Breitling B02, which was based on Caliber B01, followed two features of Breitling Cosmonaute watch wron by Major Scott Carpenter in 1962-24-hour display and manual winding. With distinct column wheel timing device, 39 jewels and high-frequency (28,800 vibrations per hour), Caliber Breitling B02 was mounted on New Breitling Navitimer Cosmonaute watch which is famous for the first Cosmonaute watch that went to space.

At 2016’s Basel Fair, Breitling launched Caliber B12 with 24-hour military time display. Thanks to self-winding mechanism, the movement supplies inexhaustible power for Breitling Avenger Hurricane watch.

Breitling B14
In 1915, Breitling invented the world’s first independent timing button at two O’clock. In memory of the history of Breitling watchmaking and the milestone, Breitling Transocean 1915 Chronograph watch was launched. To make sure the timing button continue to keep “Start-Stop-zero” operating function, self-made self-winding B14 was developed successfully by Breitling watchmakers and technicists. With three-stage mechanism and double-layer timing control system, “Start-Stop-zero” operating function works well. Thanks to patented double-layer column wheel, the movement can match with many other parts of B01. It has the best reliability and simplifies the after-sales maintenance process.

Breitling 01 Chronoworks®
As the cooperative partner of airline business, Breitling pursues excellent performance of a movement. Breitling was successful in developing Caliber 01 Chronoworks® based on Caliber 01. Excellent performance of Breitling 01 Chronoworks® was improved significantly by five major efficiency-enhancing innovations: ceramic baseplate and bridges, silicon wheels, silicon escape system, variable-inertia balance wheel and seconds pinion with elastic toothing. As a result, its power reserve was enhanced from 70 hours to 100 hours. Breitling Superocean Heritage Chronoworks® Limited Edition watch with Caliber 01 Chronoworks® made its first appearance at 2016’s Basel Fair.

Breitling self-made movements with high efficiency, reliability and high accuracy (A)

As a professional timepiece expert, one of the large independent watchmakers in Switzerland, Breitling always stick to unique style to carve out its own path. As Jean-Paul Girardin said, we are famous for producing professional Navatimer watch, and we determine the direction to move forward as a pilot takes the full control. Facing the constantly changing market situation, Breitling decided to develop self-made mechanical movements in order to preserve the independence of the brand. Breitling has developed more than 11 different kinds of self-made creative movements since 2009, reflecting independent spirit and innovation ability.

Breitling Chronomat B01
After Breitling determined to develop a self-winding chronograph movement, Breitling set up a team which made up of top watch designers and construction experts, aiming at developing new movements with high quality and high performance. In the spring of 2006, Breitling finished the first 100% self-made movements. To make sure their
performance, Breitling tested these movements again and again and optimized them constantly. As a result, the first self-made movements were passed successfully by Swiss Official Chronometer Testing Institute at the end of 2006. Finally, Breitling Chronomat B01 was born in 2007. Breitling Navatimer 01 watch was equipped with the movement to make the tribute to the 125th anniversary of Breitling. With column wheel, vertical clutch, bidirectional self-winding system and more than 70-hour power reserve system, Breitling Chronomat 01 is reliable and precise. Breitling Navatimer 01 watch had warm market response, too.

Breitling B04/Breitling B05/Breitling B35
With the increasing demand of global business travel, Breitling Chronomat GMT watch was furnished with Cal. B04, providing convenient and reliable experience for travel enthusiasts. As a self-winding mechanical movement with convenient dual time zone display, Breitling B04 is equipped with exclusive patented system-differential side gear-to-case clearance instead of ratchet system, convenient to change time zones away from any interference.

Breitling B05 is an evolution of Cal. B04, whose Worldtimer mechanical device was redesigned and innovated.
It’s the first movement that it has a city disk and 24-hour disk devise. Gear drive system of Breitling B05 makes the city disk drive, and the patented system makes the user pull the crown and rotate it, then 24 time zones around the world can be readable.

Breitling released Cal. B35 with self-winding three hands and world standard time function in 2015. It features revolutionary convenient operation. The crown is pulled out lightly and rotated forward or backwards in hour, adjusting all indicators on the dial. Though the movement is in a delicate size, it supplies over 70-hour power reserve for the watch. The strong power reserve benefits from two built-in clockwork boxes, making sure optimal kinetic energy storage and use efficiency. Shunt-wound clockwork boxes reduce the bearing pressure of the center wheel and have regular energy output. The tailor-made rator makes the delicate movement achieve the best efficiency. The movement has two patents of invention developed by Breitling, one is for the connecting device between differential gear train and the movement; the other is for the connecting device between the city disk and the movement. The innovation and functional optimization improved the performance of Breitling watches, coincident with design concept of Breitling Navitimer.

How Does A Breitling Watch With A Tudor Movement Work?

Tudor built its well-known brand by transforming Fluerier or ETA movements in the first few decades. Tudor started to collaborate with Breitling on movement swap in 2017. How Does A Breitling Watch With A Tudor Movement Work? Here I’ll analyze that Tudor MT5612 self-winding movement is transformed into Bretling B20 movement. Tudor Heritage Black Bay Chrono watch is equipped with Breitling B01 chronograph movement, and Tudor also supplies Tudor MT5612 self-winding movement for Breitling Superocean Heritage diving watch.

Breitling Superocean Heritage diving watch in 1959
Contrast between an old Breitling Superocean Heritage model and a new model

Maybe Breitling Navitimer Chronograph watch wins a high reputation all over the world, but in fact, Breitling Superocean diving watch also has a long history. In addition to Rolex Submariner watch, Omega Seamaster 300 watch, Blancpain Fifty Fathoms watch, Breitling diving watch took the fourth place at one time. Breitling Superocean diving watch which was launched in 1957 had all characters of modern diving watches, such as the rotating bezel, high visibility with luminous markers and hands, strong water resistance and so on. There is no denying that Breitling Superocean series has less influence on professional diving watch than three other watch brands, which won’t stop its own advantages in the watchmaking. We can collect a recognizable and durable Breitling diving watch at reasonable price at the exclusive store or on the second-hand market. Although Breitling diving watches were equipped with modified ETA movements totally, they were still accurate and certified by Swiss Official Chronometer Testing Institute. Comparing with self-made movements, Breitling Superocean watch was short of some technical features on movement equipment. the biggest shortcoming of ETA general movements is short power reserve for about 40 hours. Breitling changed Tudor MT5612 self-winding movement with B01 movement, helping Breitling solve movement problems completely.

Breitling named Breitling B20 movement after Tudor MT5612 movement. Viewing from the public price, Breitling
watch is more expensive than Tudor watch, so Breitling’s processing for MT5612 movement is different from the original model. Due to brand positioning, Tudor MT5612 movement has little decorative polishing, which won’t have any influence on accuracy because of the sealed watch back (except for North Flag). While Breitling polished traditional patterns on B20 movement, obviously B20 movement with Geneva patterns looks more gorgeous than the orininal model. It’s worth noting that B20 movement didn’t use silicon hairspring, so some people question that its anti-magnetic performance isn’t better. In fact, they didn’t make a big difference in the daily life since conventional Ниварокс alloy hairspring achieves certain anti-magnetic ability. With the seal back, it’s beneficial that Breitling used modified B20 movement. 70-hour power reserve enhanced Breitling diving watch. As usual, Breitling B20 movement was certified by Swiss Official Chronometer Testing Institute.

Breitling Superocean watch includes two models-42 mm and 46 mm, available in blue, brown and black. Thanks to Milan watch bracelet, Breitling Superocean watch is comfortable to wear around the wrists. At present, diving watch is very popular. The advantage of Breitling Superocean watch with B20 movement is superior cost performance.

Performance Analysis of Breitling Colt Automatic 44mm Watch

With high reliability and readability like Breitling Chronomat and Navitimer watch, Breitling Colt watch which launched in the 1980s was viewed as a watch intended for the armed forces. Breitling Colt watch’s specified appearance was defined by twenty-four hour-markers aviator-style dial and wider unidirectional rotating bezel. The understated, efficient style of the Colt Automatic perfectly reflects its original vocation, from the appearance to movement. Here we pay attention to Breitling Colt Automatic 44mm Watch.

Similar to Breitling Colt Superocean watch in the mid-1990s, Breitling Colt Automatic watch copied the rotating crown with protective devices on its both sides, aviator-watch-style Arabic numerals and wider unidirectional rotating bezel with four indicators. The satin-brushed bezel feature four rider tabs ensuring optimal protection for sapphire crystal glareproofed both sides. In addition to that, grooved scales and four raised tabs improve the operation of the bezel, it is easy to rotate the bezel even though you’re wearing gloves. Such distinctive design for the crown and the bezel has been Breitling’s feature.

Comparing with 1000 meters water resistant performance of early models, Breitling Colt Automatic watch with 200 meters waterproof depth provides fixed performance. With double insulation back, stainless steel case contributes to keep Colt watch flawless in deep-sea diving. Professional III stainless steel bracelet is equipped with
safety hook and folding clasp, suitable for you in warm or hot weather. Certainly, it’s cool to wear Ocean Racer or Diver Pro rubber band. In cold weather, you had better wear a leather strap, nice and comfortable.

Breitling Colt Automatic watch is equipped with Breitling Caliber 17, a modified version of ETA Caliber 2824-2 which has been officially certified by the Swiss Official Chronometer Testing Institute. In testing for movement performance, mainspring winds completely and works for twenty-four hours later, Colt watch almost has any error. It is a second slower around the wrist. This slight delay lasts one day, but the one second deviation falls within the timing tolerance range. It is worth noting that there is a significant difference between the dial up and the crown down after the dial runs for 24 hours. We also noticed the difference in amplitude, which dropped by nearly 60 degrees in the span of a day. To its credit, the average speed didn’t reduce with its influence.

Minute hand and second hand run along track markers, and hour hand runs along twenty-four markers and points to track hour markers. minute hand, hour hand and hour markers are covered with luminescent coating, convenient in the dark environment. Hollowed top of second hand will add to more convenience when we see the time.

In past twenty years, Breitling Colt watch attracted a large number of consumers for firmness, functionality and great readability. With the similar appearance and high performance, new Breitling Colt Automatic 44mm Watch will continue its popularity.

Breitling Transocean 38 Watch Review

When it comes to luxury aviation watches, Breitling is the name which is probably familiar to many people. As for me, I know about the watch brand, but I have never been attracted by any Breitling watch so far. I’m not an aviator, so I pay little attention to aviation-related watches and complicated dials confuse me. It makes me know about the view of the brand’s products again when I saw Breitling Transocean 38 for the first time, so I determine to get one. I want to share my review with you.

First, its dial drew my attention. Four dials in different colors are available, but the black is my favorite. I’m often inclined to those dials in light colors, but the reason for choosing the black is simple. With the black dial, polished markers and hands present a striking contrast. I like the perfect match of black and polished steel.
Second, another feature of the dial is that I can get the time clearly. Here again, polished scales and hands with white luminous coating stand out against the black dial. Simple design makes wearers keep their attention focus on the current time on the black background. In my opinion, the only fly in the ointment is the date window. I would rather not have border in the same color as the markers and hands. Without the border, the date window can blend in with the black background.
Finally, with the dial, I do appreciate that the text and branding was kept to a minimum. You’ve got Swiss Made tucked away on the bottom portion of the dial (as we have with many brands), and then, of course, the Breitling logo (in gold tone) in place of the 12 o’clock index, with the brand name below that. Normally, I would call out the appearance of gold in an otherwise silver-toned watch. I again surprised myself by liking it, as it does subtly remind you not only of the brand, but the fact that this is, indeed, intended to be a luxury watch.WOVEN BRACELET
Woven bracelet inherited the aviation theme. In my eyes, it is a more classic choice than the usual three-quarter bracelet, s well as being one that really does not show fingerprints. If the model isn’t your cup of tea, twenty different kinds of watch bracelets are available for you. For the steel woven bracelet, most people think that they adjust the sizing by manner of unclamping the clasp, sliding it along the bracelet to the desired spot, and the latching it back down. But the thicker Breitling bracelet has removable chains like the other solid bracelets.

Comparing with Breitling Transocean 46 watches, many people worry about Breitling Transocean 38 seems smaller. I think 38 mm dimension is quite appropriate for me. When I’m wearing a suit, I feel the thickness of the watch seems thicker than the actual.

In a word, I like the Breitling watch. As I have mentioned a few times, the Breitling Transocean 38 definitely has a dressier feel to it. That said, the polished steel and mesh bracelet works just fine with jeans.

Breitling Superocean Heritage Chronoworks® is a combination of superior performance and exclusive ‘engine’

Breitling combined the latest materials with advanced high technologies to design Breitling Superocean Heritage Chronoworks®, whose debut was at the Basel fair in 2016. The Limited Edition Breitling watch of 100 pieces sold for $ 39,295, five times more than Breitling ordinary Chronograph. Such high pricing made people wonder why it is worth.

High-tech movement is hard to be hidden in the overall black appearance. Breitling Superocean Heritage Chronoworks® is equipped with Caliber 01 Breitling Chronoworks® inspired by Caliber 01. As asuccessful movement, Breitling Caliber 01, self-winding chronograph movement, is furnished with a column wheel and longitudinal clutch. Its power reserve extends to 70 hours. In order to improve higher performance of Caliber 01, engineers and watchmakers have succeeded in increasing the power reserve from 70 to 100 hours, thanks to five major efficiency-enhancing innovations. The new improved version is Caliber 01 Breitling Chronoworks®.

In order to reduce the friction coefficient of the axle, baseplate and bridges are made of high-tech ceramics. In fact, this material has been used as an additive in the lubricant of high performance engines, but it is used for advanced watchmaking for the first time. Thanks to the low coefficient of friction, the shaft tip can be placed directly in the holes of the baseplate, without the protection of the ruby holes. Also it can reduce the loss of kinetic energy under
lubricant-free situation. Hence, the total number of ruby alxes has been reduced from 47 to 36.

In fact, the watch movement is in stopped state in 95% of the time, but it loses the energy every time when we restart it. In order to avoid lower the loss, Breitling adopted silicon to produce three of the most important wheels:
center wheel, third wheel and fourth wheel since silion is only half as weighty as ordinary material. These wheels are made by DRIE (deep reaction ion etching) process, which makes the whole structure more stable.

Most of energy losses occurs in motion of the escapement system, so escape system is another part need to be improved. Silicon lever and escape wheel can reduce the weight of Swiss lever escapement and the inertia in operation effectively. Optimized escape wheel makes he effective utilization rate of barrel kinetic energy increase by 42%.

Balance wheel combines the nickel ring with the brass spoke to reduce the inertia by thermal variation suppression.
Besides, it is also equiped with four metal weights, aiming at adjusting the accuracy.

Seconds pinion with elastic toothing is another important nerve center in the longitudinal clutch system and timing components. It connects the base to timing components, so that the gear teeth are more attached to the grid. It works in eliminating the friction of traditional springs and improving the transmission efficiency.

Breitling adopted matt ceramic case to show powerful and modern appearance. The operation process of Caliber 01 Breitling Chronoworks® can be seen clearly through transparent back. The design for rubber weaving band borrowed from steel weaving band.

Breitling Galactic 36 SleekT watch with diamond bezel for women

Galactic series is the good example of fashion and elegance in Breitling wristwatches, and each one was designed delicately. Rich-colored dials are crafted with diamonds, mother-of-pearl and other precious materials, conveying the elegance and glamour around the wrist to the outside. The watch case in different sizes and various bracelets or straps add more charm to Breitling Galactic. It can satisfy women’s demands on any occasion and attract lots of ladies. Equipped with accurate movements, chronometer-certified by the COSC (Swiss Official Chronometer Testing Institute), Breitling Galactic reflects elegant temperament and high-end workmanship.

Designed for women’s wrists, the Galactic 36 SleekT combines a 36 mm case (water-resistant to 100 m/330 ft), an ultra-hard scratch-resistant tungsten carbide bezel and a SuperQuartz™ movement, chronometer-certified. A champion of style and performance and a faithful companion at every moment of an active life. Breitling Galactic 36 SleekT watch with diamond bezel gives ladies a deep impression.

The combination of mother-of- pearl dial and diamond scales reflects ultimate elegance. Three bold hands and scales are coated with Super-LumiNova, and the aperture at the three O’clock displays the date. Whether in the daytime or at night, the time can be read clearly and accurately from the sapphine crystal glass. The diamond bezel
also adds noble temperament to elegant you.

Traditional round case made of stainless steel was processed specially, looking more tridimensional and smooth. Viewing from the side, the layers of the watch case and the bezel is obvious.

The distinctive crown, fluted, not only increases the beauty but is more convenient to operate. The shoulder pattern
on its both sides looks elegant and dainty.

Lugs and the case were cast together, forming sweet lines. The lugs were polished, smooth and sheeny. Their radian suits to women’s wrists better.

The watch bracelet with five rows of links brings ladies more comfortable experience of wearing. It is also equipped with a folding clasp which is easy to open and lock.

Breitling Galactic 36 SleekT with diamond bezel is not a complicated watch, and the date display and waterproof function are enough to suit daily needs. Its high performance movement guarantees the stability of the watch when
you are doing high-intensity exercise. Overall style and details were processed delicately, and the diamond bezel shows women’s charm better.

5 Specific Functions tell you how to choose a Diving Watch!

Unknown underwater world is full of exploration fun, but you would probably happen to meet unexpected danger if you don’t prepare well. A reliable diving watch can not only supply you with accurate time, but help you accomplish your wonderful journey. In addition to strong water resistance, its security also embodies another 5 specific functions.

Whether swimming or instrument operation under the water, we need flexible wrists. A diving watch fastening the wrist tightly is necessary at this time. Though many diving watches are equipped with metal bracelet, some chemical components in the sea may cause light corrosion. We had better replace a rubber band with good water resistance and corrosion resistance before we decide to dive. Nowadays, it’s a good option that some watch brands developed canvas or man-made fiber straps.

Which part does have water damage for a wristwatch? Absolutely the crown. Because the crown is the only part connecting the movement to the outside. In order to prevent the water through the crown into the machine, the screw-in crown with a waterproof rubber ring was developed by watchmakers. When the crown is screwed tightly, water will be insulated outside the watch. After upgraded, bigger fluted crown is more anti-skid and more convenient to operate under the water.

Helium Escape, which is used in professional diving watches(beyond 1000-Meter water resistance), is a professional function. When professional divers works in the deep sea, they have to stay the high pressure cabin. During that time, Helium molecules keep infiltrating the watch. Once they return to the land, the watch will explode if the high-pressure Helium can’t be escaped in a short time.

You feel your longing for the light in the dark deepsea strongly, so all diving watches are equipped with bold luminous scales and hands in order that the users can see the time clearly and precisely. In the early days, watch hands and scales were coated with radium, but the material was quitted since it has too many radioactive elements. Nowadays, Super-LumiNova, good lightfastness and colorfastness, is used the most commonly.

The rotating bezel plays an important role in alerting the diver to the diving time. The bezel was marked with these scales-15, 30, 45 (also 60-minute scale). The first quarter is colored or marked specially since the diver observes a 15-minute safety stop to reduce stress during the rising period. Most of bezels are designed as unidirectional rotating bezel in order to prevent the delay time. The new built-in chronometer bezel without rotation direction limitation will be locked by screw-in crown before entering the water.

Highly recommend the following five diving watches.
