1. Is this an original brand crystal?
No, this is a generic aftermarket mineral crystal, not from a specific watch brand. It is designed as a compatible and affordable replacement.
2. Which thickness should I choose – 0.8mm, 1.0mm, or 1.2mm?
Measure your original crystal thickness or the case bezel groove depth. Choose 0.8mm for very thin cases, 1.0mm for standard cases, and 1.2mm for cases requiring a slightly thicker crystal.
3. How do I choose the correct diameter?
Measure the inner diameter of your watch case bezel opening where the crystal sits. If replacing an old crystal, measure its diameter directly. Available sizes range from 13.0mm to 45.0mm.
