About This Crystal
A round, 3mm thick single-dome mineral glass watch crystal with a flat bottom and domed top. The polished/bevelled top edge gives a clean, finished appearance. Supplied individually as a direct replacement for worn, scratched, or cracked watch crystals.
These crystals are sold as a generic/universal replacement — the correct fit is determined entirely by diameter. Measure your existing crystal or case aperture carefully before ordering.

Compatibility
This is a universal crystal blank. It is compatible with any round watch case that accepts a glue-in or gasket press-fit crystal, provided the diameter matches. General compatibility includes:
- Fossil, Diesel, Guess, Michael Kors, Kenneth Cole, Tommy Bahama, Relic, Christian Bernard — domed 3mm mineral crystals are standard trade replacements for these brands
- Diver and waterproof watches generally — 3mm thickness (triple standard) makes this crystal well-suited to water-resistant applications
- Vintage and modern dress watches accepting a single-dome profile
- Seiko, Citizen, Bulova, Orient, Hamilton, Tissot, Omega — compatibility is possible where the diameter matches; a brand-specific or OEM crystal may also be available for these marques
Important — diameter is the binding dimension. Measure your existing crystal diameter with a digital calliper. If fitting to a gasket, order approximately 0.1mm larger than your gasket measurement. Crystals are available in 0.5mm diameter steps (15mm to 50mm) — if your watch requires a size between two increments, consider whether the next size up with a gasket will suit.
Installation Notes
- Can be glued in (with watch crystal cement) or press-fitted into a case that has a crystal gasket/retaining ring
- A crystal press is recommended for gasket-fit installations
- The flat bottom provides good hand clearance; the dome top gives a subtle magnification effect on the dial
- 3mm thickness is noticeably taller than a standard OEM crystal on most everyday watches — visually appropriate for divers and sport watches; check against your bezel profile for dress watches
