The watch bezel is the ring that encircles the crystal glass to secure it in place. It is one of the many parts of the watch case. Bezels are usually metal, but they can come in other materials such as ceramic. Rotating bezels have spiked in popularity over the years. In fact, most bezel watches feature a rotating bezel. We mainly see them on diver watches due to their useful underwater functions. Some rotating bezels are unidirectional, meaning they only rotate anti-clockwise. Others are bi-directional; they rotate both clockwise and anti-clockwise.
Most bezel repairs are needed due to wear & tear. Dirt and grime usually accumulate underneath the bezel rendering it immobile. Other bezel repairs include damaged inserts replacements, polishing and resurfacings.
