The Wonderful Watch Bezel: Types, Styles, and Operations

While the face of the watch often steals the show and the movement gets all the technical glory, the bezel surrounding the watch's face gives it more character or functionality or both. From adding a pop of sparkle to giving your timepiece an extra tool of precision, the bezel is where design meets purpose. 

A rotating bezel helps divers time their underwater adventures, a sleek scale guides pilots through complex calculations, or a dazzling gem-encrusted circle turns heads at a gala. 

In this guide, we’ll explore the world of watch bezels, breaking down their types, styles, and clever operations. 

What is a Watch Bezel?

A watch bezel is the outer ring that surrounds the watch crystal, typically located on the face of the watch. It serves both functional and aesthetic purposes. The bezel can be fixed or rotating. A bezel often contains markings such as minute scales or tachymeters, adding to its functionality.

How Do Bezels Improve the Looks and Functionality of Your Watch

Many styles of watches have different bezels. Bezels significantly add to the looks and functionality of a watch:

1. Improving Aesthetic Appeal

The bezel is a defining feature of a watch’s design, framing the dial and often serving as a canvas for artistic or luxurious touches. The bezel can transform a watch into a statement piece, whether it's a clean stainless-steel finish, a vibrant ceramic insert, or a diamond-encrusted rim. It also allows brands to differentiate models through unique shapes, textures, and colors.

2. Adding Functionality

Functional bezels add an extra layer of utility to a watch. For instance, a dive watch’s unidirectional bezel provides a simple yet effective way to measure elapsed time underwater, giving divers a critical safety tool. Similarly, tachymeter bezels help calculate speed while GMT bezels enable tracking multiple time zones. These features turn a timepiece into a practical instrument for specific tasks.

How to Rotate and Use a Rotating Bezel

Rotating bezels are versatile tools that enhance the functionality of a watch, particularly for timing, tracking time zones, or other calculations. 

1. How to Rotate a Bezel

• Unidirectional bezels: These bezels rotate counterclockwise only. To adjust, grip the bezel firmly and turn it to align the zero marker (often a luminous pip) with the minute hand.
• Bidirectional bezels: These rotate both clockwise and counterclockwise. Adjust by turning the bezel in the desired direction to align with your reference point.

Note: Avoid forcing a bezel beyond its limits. If it feels stuck, have it checked by a professional.

2. Common Uses of Rotating Bezels

A. Measuring elapsed time (Unidirectional bezels)

1. Align the zero marker on the bezel with the current position of the minute hand.
2. As time passes, observe the position of the minute hand relative to the bezel markings.
   • For example, if the minute hand points to the "30" marker on the bezel, 30 minutes have elapsed.

B. Countdown timer (Bidirectional bezels)

1. Rotate the bezel to align the desired countdown time with the minute hand.
   • For instance, if you want to count down 15 minutes, align the "15" bezel marker with the current minute hand position.
2. Watch the minute hand move toward the zero marker as time decreases.

C. Tracking a second time zone (GMT or Bidirectional Bezels)

1. Set the bezel’s 24-hour scale to align with the second time zone hour hand or reference time.
2. Read the second time zone directly from the bezel using the GMT hand or current time indicators.

D. Using a dive bezel for safety

1. Align the zero marker with the minute hand before descending.
2. Monitor the elapsed time during the dive to ensure you stay within your planned limits.
   • For example, a 45-minute dive plan means ensuring the minute hand doesn’t pass the "45" marker on the bezel.

Tips for Effective Bezel Use

• Luminous bezels: Use watches with luminous bezel markings for readability in low-light conditions, especially during diving or nighttime use.
