Restore your watch with this replacement ceramic bezel insert, designed for watch cases compatible with the Longines HydroConquest 43mm L3.782 series.

The insert is constructed to follow the original profile, proportions, and bezel channel seating, allowing it to fit securely and align correctly once installed.
