Dive watches are popular and have become a diver’s essential, designed to be functional and practical by watchmakers. Although not many divers are using it for dive-related purposes, dive watch enthusiasts favor dive watches.

The structure of a diving watch is an exciting subject for watch fans. It is like the standard timepiece, but the functionality differentiates it with the usual wristwatches. The necessary parts of the dive watch, which are most likely present in a typical watch also, are the case, dial, bezel, movement, and strap.

1. Case
To ensure the watch is optimally functional, it depends on the materials used. The case is a crucial element to protect the watch against water and exposure to unfavorable environments. Watchmakers are keen on checking the component used and establish it follows the industry’s standard-based guidelines set by the International Organization for Standardization (ISO). The ISO 6425 regulates the standards for diving watches, including the water-resistance test. Some diving watches also have a helium escape valve that works when the change in pressure reaches a critical level.

2. Dial
Dials with intricate designs are rarely found in dive watches. Instead, a dive watch dial should be easy to read and have luminous markings for the hands and indexes. This feature facilitates readability for divers underwater.

3. Bezel
The rotating bezel is the part of the watch attached to the case. It is common for diving watches to follow only a counterclockwise direction. It helps divers in tracking elapsed time for an hour from a specific point.

4. Movement
For a dive watch, the movement should be sturdy. It must be reliable and functional to make sure that the watch works accurately, even in harsh situations.

5. Strap
The strap is also an essential part of a dive watch. Rubber and canvas straps or stainless steel bracelets are usually used in dive watches. Just like the movement, the strap must be durable against water, sunlight, and humidity. Another option is the use of NATO straps from the original NATO stocking number.
