Q1: Is this crystal made of sapphire?
A: No. This is mineral glass – lower hardness but more affordable. For sapphire, please choose our sapphire crystal series.
Q2: How to choose the correct thickness?
A: Measure the thickness of your original crystal with calipers and select the exact match (1.5mm or 2.0mm). A mismatch may prevent seating or cause sealing failure.
Q3: Is this crystal compatible with all watches?
A: It fits watches with press‑fit cases. Measure the case groove inner diameter and select a crystal 0.05‑0.10mm smaller. Not for screw‑down or adhesive‑mount crystals unless UV glue is used.
Q4: Can mineral glass be polished?
A: Light scratches may be polished (limited effect), but deep scratches require replacement – polishing may distort the surface.
