In addition to its beautiful appearance and durability, the most interesting is the rotating bezel. The rotating bezel is arguably the most iconic feature of a diving watch.
Specifically, the diving watch’s rotating bezel serves as a reminder of the diving time. The scale of the common rotating bezel is usually 15, 30, and 45, because the oxygen cylinder for general diving can only maintain a dive time of 30 to 45 minutes. Some diving watches have a color or special logo in the first 15 minutes of the rotating bezel, because divers strictly follow the 15-minute safety stop when ascending to decompression diving, so when the time has passed, you can Go home.
The use of a diving bezel is also very simple. Generally, as long as you rotate the rotating bezel during diving, align the 0 scale on the rotating bezel with the minute hand, and then look at the scale on the rotating bezel after the minute walk to know the time spent diving.
The rotating bezel of the diving watch is reverse rotation, and it must only be able to rotate in the reverse direction. Some bezels on the market equipped with two-way rotation are not diving watches in a strict sense. Why do you say that? For example, if you turn the bezel in the wrong direction during a dive or if you turn the bezel due to touching, it is nothing more than reminding you to get out of the water in advance. However, if you wear a two-way rotating bezel watch, a clockwise bezel misoperation occurs during the dive, and the countdown to the dive that has begun is reset to zero, which can be very fatal to the diver. The two-way rotating bezel is mainly used to calculate time, such as the time taken by a sailing boat to pass between two buoys. It is not used for diving.
In 1953, Blancpain launched the Fifty Fathoms diving watch, which was also the first watch with a reverse rotating bezel, and applied for a patent. At about the same time, Rolex launched the first Rolex Submariner, but the submariner actually put on the reverse rotating bezel after the end of the 1980s Blancpain’s patent protection period.
As an important part of diving watches, various brands have done a lot of work on diving bezels, from materials to craftsmanship. For example, the well-known Rolex ‘Water Ghost’ series, the bezel is made of high-tech ceramics. Because ceramics have the characteristics of anti-corrosion, anti-scratch and light weight, they have basically become the standard for modern diving watches. And this year, the fusion process of the new marine universe rubber and ceramic bezel introduced by Omega and the new Fifty Fathoms Bathyscaphe bezel introduced by Blancpain are more complicated and beautiful with the fusion of ceramic bezel and liquid metal scale.
Of course, the reverse rotation of the outer ring is also disadvantageous. After all, it is not integrated with the case, but is fixed on the case. The slight gap makes it easy for the watch to penetrate into the gap between the case and the bezel during the underwater use of the watch, causing great damage to the watch.
The emergence of the counter-rotating inner ring has eliminated this hidden danger. For example, the Audemars Piguet Royal Oak offshore diving chronograph puts the reverse rotating bezel into the mirror and blends with the dial. The specially adjusted crown adjustment not only eliminates sand, but also a rotating waterproof crown After the crown is locked, it also avoids the misoperation of the underwater bezel rotation, which is safe and reliable.
In addition, IWC also has a case design with an inner and outer rotating bezel. It combines the advantages of a rotating inner ring with the ease of handling of an outer bezel. The operation is also more convenient. Even when wearing diving gloves or cold fingers, you can set the time in minutes. Also for safety reasons, only allowed to rotate in a counterclockwise direction. In this way, even if the bezel is inadvertently adjusted, the time at the zero position can be ensured, that is, the time required for the diver to safely rise to the surface without decompression is not exceeded.
