How to use Diver Watch Unidirectional Bezel?

Diver watch bezel

The diver watch bezel, also known as unidirectional bezel, is a basic feature for diver watch. It is the most simplest way to keep track of diving time. The diver watch bezel allows indicating the elapsed time or remaining time.

The bezel is unidirectional as this ensures even if you rotate the bezel accidentally, it can only increase the apparent elapsed time. This is a “fail safe” feature for a diver.

How to measure elapsed time?

Omega Mens 2222.80.00 Seamaster

Bezel marketer is pointing to minute hand

1) Rotate the bezel until the bezel marker is pointing to the minute hand

2) Read the elapse time by the bezel scale

How to measure remaining time?

Omega Mens 2222.80.00 Seamaster

Rotate the bezel until 40mins is pointing to minute hand

1) Figure out how long you want to measure, e.g. 20mins

2) 60mins minus time required, e.g. 60mins – 20mins = 40mins

3) Rotate the bezel until the 40mins is pointing to the minute hand

4) The remaining time can be read by 60 minus the bezel minute indicator

5) When the minute hand is pointing to bezel marker, time is up. i.e. 20mins passed
