The Basics of the Rotating Bezel

As a functional timepiece, a dive watch is prominent because of its rotating bezel. Perhaps, it is one of the main distinctive parts that set a diving timepiece apart from other watches. Although not all divers use a dive watch, it is essential to learn how the bezel works.

In a dive watch, the bezel can either be an external or internal one. However, the most common is the external bezel, while a few brands have internal bezels. Most external bezels are unidirectional, although some are designed to move in both directions.

For Aquinus, the rotating bezel is unidirectional and moves only in a counterclockwise direction. The primary function of a bezel is to track elapsed time underwater for up to 60 minutes at most. This tracking feature is vital for divers in calculating their ascent point, especially if they do not have a computer watch on the wrist.

It is also important to note that the bezel is never used to calculate the remaining air in a diver’s air tank and is one common misconception when it comes to bezel’s function.

How to use the rotating bezel?

To measure the elapsed time, position the bezel’s marker to the position of the minute hand. The bezel’s intervals are most likely in multiples of 10. To read the elapsed time, start from the marker up to the current position of the minute hand.

On the other hand, to check the remaining time, all you need to do is to set the bezel’s marker to the ‘scheduled time.’ The remaining time means the point from the minute hand to the marker.
