✅ Fits
A generic aftermarket blank suitable for a wide range of round watch cases. Fit by crystal cement (adhesive) or by pressure-fitting into a nylon or rubber gasket, depending on the case design.
- Suitable for many Seiko and Citizen models using a mineral domed crystal in this thickness
- Compatible with Fossil and similar fashion-watch cases using glued or gasket-fit round crystals
- Indicative fit for some Bulova models in the 35.5–42mm diameter range, based on aftermarket cross-reference
⚠️ Please check your case opening diameter carefully before ordering — this is the critical fitment dimension across the 23–50mm range. The 1.5mm edge thickness is greater than a standard 1mm crystal, which is normal for this profile and shouldn't affect fitment in most cases, but is worth confirming against your original crystal.
