This is a universal flat mineral glass replacement, made across a wide diameter run from 17.1mm through to 50mm in 0.1mm steps up to 40mm, then in 0.5mm steps up to 50mm. Rather than being tied to one watch brand or model, it's sized to fit whichever watch takes a flat crystal of the matching diameter — simply select the size that matches your original glass when ordering.

⚠️ Please check — measure your old glass straight across its widest point (edge to edge, not the case opening) before ordering, and select that exact diameter from the size menu, as mineral glass is rigid and won't seat correctly if the diameter is even slightly out.
