A reliable, dependable, watch is a crucial tool in any diver’s toolbox, figuratively speaking. Selecting the appropriate watch, while a complicated process, can be diluted down to a few crucial steps or points of emphasis.
1. Water and Corrosion Resistant Case.
Diving watches are universally constructed to withstand water pressure up to a specific manufacturer determined rating. Its is also important to select a watch that has a case, strap, and face, designed to withstand the corrosive nature of many of the chemicals commonly found in oceans, lakes and rivers. Many watches are also designed to withstand external magnetic pressure and moderate amounts of impact related stress.
2. Rotating Bezel.
A rotating bezel allows a watch user to keep track of elapsed time. The outside of the watch bezel will rotate, allowing the watch user to keep track of the passage of time, without having to remember a specific time when they begin the tracking process. Many watches also come with self-locking bezels, reducing the possibility of accidental movement. The less you have to worry about while diving, the more energy you have to spend towards staying alive.
3. Helium Release Valve.
Only a concern with ultra deep dives, a helium release valve allows for the venting of the helium gas that penetrates watches during technical dives, or dives in excess of two to three hundred feet. Without this feature, watches used for dives of extreme depths in helium rich environments would often experience rupturing of the case, or an exploding watch face.
What appears clear and decipherable standing in a watch shop is often much different then what can be easily seen in 85 feet of murky water. Quality dive watches come with a face and dial composed of easily readable, brightly colored design, of high contrast colors.
5. Power Reserve Indicator.
Battery operated diving watches, and even those function with a batter power backup system, must come equipped with some for of indicator to alert the diver to current power levels. This is intended to avoid potentially dangerous or confusing situations associated with watch dependability.
6. Crystal Case.
A quality dive watch will have a face fabricated of extra thick crystal design. This is a result of the extra external pressure many dive watches will be under during the course of normal use. Without this extra effort, many dive watches would experience leaking, cracking, or even complete face implosion, when used at even moderate depth levels. The case face should also be scratch and streak resistant to avoid visibility complications and concerns.
