Mastering the Inner Bidirectional Bezel: Tips and Tricks for Use

For divers and outdoor enthusiasts, a reliable dive watch is an essential tool, and a bidirectional rotating bezel is a key feature that aids in tracking elapsed time during underwater adventures. While many are familiar with the traditional unidirectional bezel, some dive watches come equipped with an inner bidirectional bezel, offering additional functionality and versatility. In this blog post, we'll explore the inner bidirectional bezel, providing you with tips and tricks to master its use and enhance your diving experience.

Understanding the Inner Bidirectional Bezel:

The inner bidirectional bezel is a unique feature found in some dive watches. Unlike the traditional unidirectional bezel located on the watch's outer casing, the inner bezel is positioned beneath the watch crystal. This design offers protection against accidental rotation and adds an extra layer of safety for divers. 

Setting the Dive Time:

To use the inner bidirectional bezel effectively, start by setting your desired dive time. Before entering the water, align the zero or starting point of the inner bezel with the minute hand on your watch's main dial. This action synchronizes the bezel with your dive time, allowing you to track your remaining dive time at a glance. 

Tracking Elapsed Time:

As you descend into the depths, monitor your dive time by observing the position of the minute hand relative to the inner bezel. As time elapses, the minute hand will move away from the zero point on the inner bezel, indicating the time that has passed since the start of your dive.

Adjusting for Safety Stops:

Dive tables often recommend specific safety stop durations at various depths to prevent decompression sickness. The inner bidirectional bezel can help you time your safety stops accurately. Simply rotate the inner bezel to align it with the recommended safety stop time for your dive depth, and then monitor your progress during the stop. 

Emergency Use and Redundancy:

One of the advantages of the inner bidirectional bezel is its redundancy in tracking dive time. If the external bezel on your watch becomes accidentally moved during a dive, the inner bezel provides a reliable backup for tracking elapsed time and ensuring safe ascent and decompression. 

Mastering the use of the inner bidirectional bezel enhances your dive watch's functionality and safety. It's a valuable tool for tracking dive time accurately, especially during safety stops and critical phases of your underwater adventure. By understanding how to set, adjust, and read the inner bezel, you can make the most of this feature and ensure a safe and enjoyable diving experience. 


As you continue to explore the underwater world and rely on your dive watch for timing and safety, remember that the inner bidirectional bezel is there to support you. With practice and familiarity, you'll find it to be a trusted companion on your underwater journeys, helping you stay on time and ensuring that your dives are both memorable and safe.
