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. What is the difference between single domed and double domed?
Single domed has a curve only on the outer side (flat on the inside), while double domed is curved on both sides. Single domed provides a classic raised look; double domed reduces glare further and offers a more pronounced vintage appearance.
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 23.0mm to 40.0mm.
