🔧 What it does & how to use
This is flat acrylic sheet stock — raw blank material, not a finished crystal cut for a particular watch or brand. It's the standard supply hobbyists and repairers reach for when a watch needs a replacement crystal that's no longer available off-the-shelf, or has an unusual case shape a stock crystal won't match. Choose the thickness closest to your original crystal, then cut and fit it yourself:
-
Select thickness: match it as closely as possible to the crystal you're replacing.
-
Measure the bezel: take the internal diameter of the opening the crystal sits in.
-
Cut oversize: cut the acrylic slightly larger than the bezel opening, as the fit relies on compression (a tension/friction fit).
-
Refine the edge: file or sand the diameter down gradually, testing the fit against the bezel repeatedly as you go rather than cutting straight to size.
-
Fit the crystal: press it into the bezel — a crystal press gives the cleanest result, though gently warming the bezel and pressing by hand also works.
⚠️ Please check your bezel diameter and required thickness before cutting — this is universal blank sheet stock to be shaped to fit, not a ready-made crystal for any specific brand or model.
