Divers Watch Features

When buying a divers watch there can be many features that are dissimilar between manufacturers, the list here are some of the features that you will find on a typical divers watch.

Watch Case

The watch cases of diving watches must be adequately water and pressure defiant to with stand the military when there under water and be able to experience the corrosiveness of seawater, so the watch cases are typically made out of materials such as stainless steel, titanium, earthenware and synthetic resins or plastics. The case must also provide protection against external magnetic influences and shocks.

Elapsed time controller

Analog divers watch will often highlight a rotating bezel, which is used to read elapsed time from a definite point. This is used to compute the distance of a dive. The bezel is used by turning until you can align the zero on the bezel with the watch's seconds or minute's hand. As time elapses the reading can be read of the bezel. This will save the scuba diver from having to achieve the subtraction that would be indispensable if the watch's quarterly dial was used and the plus of having a big dial to read when underwater. On a divers watch the bezel is "unidirectional", meaning the bezel can be turned in a single direction as turning it the wrong way can so not to increase the distance of time under water. So the bezel can only move in a way that will give a shortened time underwater. Digital dive watches commonly achieve this function by use of a appropriate stop watch function. Digital dive watches may also highlight a depth gauge and logging features.
Strap/bracelet

Generally a divers watch features a rubber, silicone rubber or polyurethane strap or a metal bangle of adequate distance to allow the wearing of a wet or dry suit. For this bracelets often have a (concealed) Divers postponement deployment clasp by which the bangle can be appropriately extended.

Bezel Markings

Most modern dive watches with conspicuous 15 or 20 little markings on their bezels, are the result of copying of a Rolex bezel develop back from the 1950s. Back then divers typically planned a dive to a unavoidable maximum depth based on Us Navy dive tables, and dove according to the planned dive profile.

Crown

The typical analog divers watch must have a water defiant crown else it would flood. Often the crown has to be unscrewed to make any adjustments to the time and date and afterwards tightened to restore the water resistance of the watch. There are however models that have crowns that are operated like the crowns of general no diver's analog watches. Screw down locking crowns and traditionally operated water defiant crowns can not be operated under water.
