Every diving watch has a common important feature, which is the rotatable bezel. And many friends do not know what the actual use of this design is, just thought it was an interesting decoration. In fact, what this rotating bezel really does is remind the diving time. Today’s watch home will introduce you in detail.
The role of the rotating bezel
The scale of the rotating bezel is 15, 30, 45, because oxygen cylinders for general diving can only adhere to 45 minutes, and some are marked with 60 minutes. The first 15 minutes are color-coded or specially marked. Divers will strictly follow a 15-minute safety stop during ascent to release the nitrogen absorbed from the cylinder completely. Normally, just turn the bezel during diving, align the 0 scale on the bezel with the minute hand, and then look at the scale on the bezel after the minute walk to know the time spent diving.
Blancpain launches Greyscaphe watch with grey plasma ceramic submersible
Inheriting the tradition of all great diving watches, every 50 噚 Bathyscaphe diving watch is equipped with a unidirectional rotating bezel, which can rotate evenly counterclockwise in a fixed unit. During the dive, the second hand is clearly visible and can be used to indicate the normal operation of the watch. This fifty-foot Bathyscaphe diving watch is water-resistant to 30 bar, which is equivalent to a depth of about 300 meters. The movement guarantees a five-day power reserve and stable power transmission. The movement also uses a silicon hairspring. Its key characteristics include: low density and light weight; strong shock resistance; and good antimagnetic performance. In addition, Cal for sports. The 1315 movement is also equipped with a beryllium bronze alloy balance wheel and a gold square-head fine-adjustment screw, which ensures accurate precision while achieving effective precise adjustment. It belongs to the Fifty Fathoms series with the tradition of ‘Iron Blood Army Soul’. Each of the deep submersible Bathyscaphe watches is equipped with NATO military NATO straps or marine canvas straps.
Why the bezel must rotate in one direction
Underwater time means life safety, and one-way rotation is extremely important for diving timing. One-way rotation means that the bezel will only be retrograde. Even if it is accidentally touched during the diving operation, it will only cause you to shorten the diving time to ensure safety. And if the bezel can be turned in both directions, especially in the forward direction, users may mistakenly think that there is still a lot of time, causing hidden dangers to diving safety. So the concept and design of the unidirectional rotating bezel is very clever and practical.
Panerai Luminor Submersible 1950 47mm Professional Dive 3-Day Power Reserve Automatic
Luminor Submersible 1950 Carbotech 3 Days
The Automatic 3 Days Power Reserve Automatic watch contains a new and extraordinary technological innovation: its case is made of carbotech, a composite material based on carbon fiber. Luminor
The 1950 case (47 mm in diameter) was developed by Panerai in the late 1940s and was worn by Italian naval commandos. This model incorporates a rotating bezel with a small stud logo, inspired by Panerai A watch created for the Egyptian Navy in 1956. The bezel can only be rotated counterclockwise to calculate the dive time: This is a very useful feature for a professional diving instrument. The watch has been tested and has a water resistance of up to 30 bar (about 300 meters).
How to use the rotating bezel
Method 1: Normal timing method. Before diving / other timing activities begin, rotate the one-way bezel to align the initial diamond mark with the points. The time that the minute hand passes on the one-way bezel is the time that your dive / other timing activities have been performed.
Method two: countdown method. Before diving / other timing activities begin, calculate the total time you want to spend underwater / activities, rotate the unidirectional bezel so that there is exactly a time difference between the minute hand and the initial diamond mark (for example, the current time is 10 : 10, need to dive for 15 minutes, then rotate the one-way bezel and rotate the initial diamond mark to 10:25 on the dial scale.) Then when the minute hand approaches the initial diamond mark, it means that the dive / activity time is about to run out. The countdown method requires a one-step preset calculation. Although it is slightly more cumbersome than the normal timekeeping method, it increases the sense of urgency when time runs out, and reminds users to pay attention to time.
