What did divers use before dive watches? Panerai supplied dive watches to the Italian Navy in the 1930s. Omega launched the rectangular Marine in the early 1920s. Back then, watches were not made for divers. In the past, divers mounted pocket watches on the inside of their helmets.
Bracelet Extensions vs Flexible Straps. Over a wet suit, you will need extension in order to wear your watch. Deep under water, due to an increase in pressure, it will cause your suit to become looser. Rolex has an easily adjustable clasp extension. Some rubber watches have ridges and this is quite usual as well. An example would be the Seiko Marinemaster 300.
The Basics of the Rotating Bezel. Align the 12 o’clock bezel with the minute hand. It is often uni-directional for the diver’s safety. Do not remove the watch once you are in the water. In addition, try to operate the bezel with only 1 hand. Internal bezels are harder to operate, unfortunately. Some bezels have locking mechanisms to prevent excessive turning. An internal bezel looks more elegant as the bezel cannot gather dust. The IWC aquatimer has managed to innovate a watch with both internal and external rotating bezels. This is an engineering marvel.

What Makes a Dive Watch a Dive Watch? A dive watch should be at least 100m water resistant and satisfy the requirements in ISO 6425. Very few watches are certified ISO 6425. There are physical requirements and methods for testing them. The watch must have a bezel etc. In addition to a visibility test, there are also other tests like temperature, salinity, reliability under water etc. There are also anti-magnetism and shock resistance tests. If you see the word ‘divers’ marked on the watch, it means that it has passed the ISO 6425 standards.
Saturation Diving, Helium Valves, and ‘Extreme’ Dive Watches. Saturation diving is where the diver needs to live and work under water in a pressurized meeting for up to several weeks. Due to the pressure built up inside the watch due to the effective sealing upon surfacing, the watch crystal might pop out. In 1967, Rolex worked with COMEX to produce the Sub 200T. Omega developed a large ‘Super Comprex’ watch. Only very few watches have a helium release valve as these watches typically have water resistance up to at least a 1,000 metres. Does a professional dive watch need a helium escape valve? Ask yourself: ‘Why not?’
