4mm Extra Thick Flat Round Mineral Watch Crystal Glass Lens Replacement UK

Flat round mineral glass watch crystal, 4mm thick. Extra-thick glass, flat on top and bottom with no dome.

Diameter decides the fit. Match it to your old crystal or to the bezel seat (the recess the crystal sits in) and it suits any round case that takes flat glass.

Measure your old glass edge to edge with calipers. If it's gone, measure across the seat. At 4mm this is thicker than a standard watch glass, so it suits cases with room for the extra height.

Fitting notes

Fits by pressing into a plastic crystal gasket or by gluing into the case. Check the seat depth before fitting.
