Definition
The bezel is the outer ring that surrounds the dial of a watch. It can be fixed or rotating and is often used for additional functions, such as timing, indicating a second time zone, or as a tachymeter. The bezel is an important functional and aesthetic part of the watch, contributing to its durability and protecting the crystal.
Origin
The word “bezel” comes from the French “biseau,” which means “angle” or “inclined edge.” The use of bezels in watches became popular in the 20th century, especially with the advent of dive watches and other sports watches, where the additional functionality of the bezel was essential.
Use
Bezels are commonly used in dive watches, pilot watches, sports watches, and luxury watches. A rotating bezel, for example, allows divers to monitor dive time, while a bezel with a tachymeter can be used to measure speed.
Examples
The Rolex Submariner and the Omega Seamaster are famous examples of dive watches with rotating bezels. The TAG Heuer Carrera uses a bezel with a tachymeter for timing functions.
Related Terms
- Tachymeter: A scale on the bezel used to measure speed.
- GMT: A bezel with 24-hour markings to indicate a second time zone.
- Cerachrom: A type of ceramic material used in some modern bezels.
Tips
When choosing a watch with a rotating bezel, it is important to check the ease of rotation and if it has firm locks in specific positions to avoid accidental movements.
Fun Facts
The bezels of dive watches are designed to rotate in only one direction (counterclockwise) to prevent accidentally showing a longer dive time than the actual, which could be dangerous. Some bezels are made of materials like ceramic to resist scratches and discoloration.
