This is a flat, 1mm-thick replacement crystal suited to watch cases with a matching flat crystal seat. Choose the diameter that matches your original glass to get a snug, correct fit.

⚠️ Please check the exact diameter and profile of your existing crystal before ordering — this is a flat crystal only, so it won't suit cases designed for a domed or tension-ring crystal, and even a small size mismatch will stop it seating correctly.
