Dive Watches Frequently Asked Questions

As a tool watch, diving watches are not merely just like casual timepieces. Their functionalities are designed to withstand extreme conditions underwater. While it is common knowledge that a watch is for timekeeping, for diving watches, it is different. There are concepts to understand and questions to use a dive watch at its optimum state fully. Here are some of the commonly asked questions about diving watches.

1. What is a helium valve?

Also known as the helium escape valve, this is an optional feature in some dive timepieces that functions as an escape channel for the gas, helium. The helium valve is applicable in extreme diving explorations (with depths more than 200 meters or 20 ATM).

2. What is water resistance?

In dive watches, the concept of water resistance is essential. It is sometimes referred to as the watch depth rating or the static pressure that the watch can withstand. It is measured in ATM.

3. What is a rotating bezel?

The rotating bezel is a unique feature of a diving watch. It is used to measure the elapsed time underwater. The bezel’s markings are equivalent to an hour and are used by divers in how long they have submerged in the water already.

4. Are all bezels unidirectional?

Most bezels are unidirectional following a counterclockwise direction.

5. What makes the dial glow underwater?

The dials need to glow underwater to provide better time visibility to divers. The glow comes from a luminous material used on the dial indices and hands, often made with tritium.

6. What’s the difference between a dive watch and a dive computer?

When it comes to the appearance, the two tools look quite similar but differ only on the features and complexities.
