More Than Just An Accessory - Diving Watches

The unpredictable underwater world is particularly important for the grasp of time. Therefore, as a watch with special functions, diving watches are not only an accessory for diving enthusiasts, but also an important tool to ensure the safety of divers. . In short, a diving watch is a timepiece that can accompany you to dive deep into the sea. Compared with ordinary waterproof watches, it has to pass more stringent regulations.

The birth of diving watches can be traced back to the beginning of the last century, when watchmakers changed the case of the watch from a gland-type design to a screw-in design. This design greatly improved the waterproof performance of the watch. Prior to this, the waterproof of the watch mainly relied on adding a waterproof case, which not only increased the volume of the watch, but also made manual winding quite troublesome. Constant opening and closing of the outer case naturally affects the sealing of the watch over time, resulting in damage to the waterproof function, so the design of modern diving watches came into being.

Although this design solves the waterproof problem of the case, there is still a defect, that is, the crown. When adjusting the watch, the pulled out crown becomes another channel for water to enter, which can also cause damage to the watch. Early watchmakers solved this problem through some crude sealing materials, such as cork, leather, felt and the like. These exposed waterproof materials will naturally form wear and tear over time, and it is very troublesome to replace them with new ones. Faced with this problem, Hans Walsdof, one of the founders of Rolex, took the lead in solving this problem and gave birth to the famous Oyster case. This design moves the waterproof function of the watch from the outside of the case to the inside of the case, and uses lead as the sealing material, which greatly improves the waterproof performance of the watch and prolongs the service life of the watch.

The rotating bezel is another iconic accessory of a diving watch. For divers, due to the limitation of oxygen, underwater timing reminder is very important for them. Accurate time control can prevent divers from decompression sickness due to insufficient oxygen or too fast ascent. Regarding the rotating bezel, I have to mention Blancpain. The brand successfully developed the first generation of the Fifty Fathoms diving watch in 1953 and applied for a patent for it.

As people explore more and more unknown areas, many deep diving workers have encountered another problem. That is, when diving to a certain depth, the watch may be crushed due to excessive underwater pressure. At this time, the helium exhaust function of the diving watch is needed to solve this problem. A diving watch with a helium escape valve can easily discharge the helium accumulated in the watch to the outside of the watch, maintain the balance of internal and external pressure, and ensure the normal operation of the watch. The representative watch of the helium escape valve is the Omega Seamaster series. Although many watch brands have subsequently introduced automatic helium escape watch designs, Omega has always followed the classic manual helium escape design in the Seamaster series.
