What are the Basic Parts of a Dive Watch?

Features and mechanisms of dive watches vary from model to model. But the main focus of these timepieces is to ensure efficient and safe diving. For this, learning how to read dive watches is as important as learning how to use them. So, you can read these watches correctly when you become well-aware of the different parts of them.

The Case

The external shell of dive watches is known as the case. The responsibility of the watch case is to protect the internal components safe from damage, dust, dirt, etc. Generally, the case is made of robust and durable material so that the timepiece can withstand pressure. Maximum dive watches come with a 100m water-resistance feature.

The Band

This part is also known as the strap. It is attached to the timepiece case. Also, it allows you to wear the watch securely and snugly on the wrist. Different materials such as plastic, rubber, etc., are used to manufacture watch bands. Besides, the timepiece band should provide comfort when you wear dive watches. You will be unable to have an efficient dive with an uncomfortable watch band.

The Rotating Bezel

The rotating bezel is the main part of a dive watch. Due to this part, these watches are called dive watches. Every dive watch comes with a rotating bezel that rotates 0 – 60. It counts the minute you spend underwater.

You will find increment markers in the bezel, generally an increment of 5 or 10 minutes. The 1st 15 minutes will be marked in 1-minute increments. Thus, a diver will know when to stop decompression. At the same time, it will let you know how long you were underwater.

The Movement

For the functionality of a dive watch, it is powered by automatic movement or battery. When quartz is used to power it, the timepiece gets power from the battery. This way, the quartz gets electrified and resulting in secondhand ticks.

On the other hand, when you wear the timepiece, the automatic movement will wind the spring. Then, the spring distributes the restored energy to let the secondhand tick. Using a battery is unnecessary in automatic dive watches. For this, people prefer automatic watches over quartz dive watches.

The Illumination

This is a mandatory feature of a dive watch. Since lights are unavailable quite often underwater, dive watches should come with the luminous feature to track the time.

Most dive watches have illuminated numbers so that you don’t face trouble tracking the time in low light conditions.


This is another mandatory feature of dive watches. If a watch meets all the mentioned above but doesn’t have a water-resistance feature, it can’t be considered a dive watch.

100m or 330 ft. should be the minimum water resistance of a dive watch.

How to Use a Dive Watch following a Correct Way

Now, you already got ideas about the different components and features of a dive watch; it is time to learn the using procedure.

(30-60) minutes = 30 minutes. This will help you to know the difference.

Then, set the bezel ring to ZERO. When the minute hand in the bezel ring reaches 30, it means 30 minutes have passed. Isn’t it straightforward to understand?
