Buying Guide
Key considerations for choosing a high dome watch crystal include size, material, and fit. Acrylic and plastic domes are affordable and impact-resistant, while sapphire options offer better scratch resistance for premium finishes. Measure your case diameter precisely and confirm the dome curvature to avoid gaps or binding.
- Size accuracy: Use a caliper to verify diameter and edge thickness before purchasing. A misfit can cause bezel interference or water intrusion.
- Material choice: Acrylic domes are affordable and easy to work with; sapphire domes protect against scratches but require careful handling during installation.
- Dome profile: High-dome designs add depth and a contemporary look but may affect legibility in certain lighting; test fit with dial visibility in mind.
- Number of pieces: For hobbyists, sets with multiple sizes simplify replacements; for professionals, bulk kits reduce reordering frequency.
- Installation: Some domes are single-piece lenses; others may require additional gaskets or mounting steps. Follow manufacturer guidance when replacing.
