✅ Fits
Suits any watch case originally fitted with a flat 3mm mineral crystal within the 30mm-40mm diameter range. Measure the diameter of the old crystal (or the case seat it sits in) and choose the matching size — mineral glass is hard-wearing and far more scratch-resistant than plastic/acrylic.
⚠️ Please check your case takes a flat crystal (not domed) at exactly 3mm thick before ordering, and measure the diameter carefully — mineral glass doesn't flex like plastic, so an incorrect diameter or thickness won't seat properly. A 2mm-thick version is available separately if that's what your case needs.
