Important: Always measure the internal diameter of your watch case or crystal seat carefully before ordering. These crystals can be pressure-fitted using a crystal gasket or adhesive-set depending on your case design. Select your required size from the variation menu.

Notes

• This is an aftermarket replacement crystal — not OEM manufacturer stock
• Suitable for both professional watchmakers and hobbyist repairers
• Mineral glass is harder and more scratch-resistant than acrylic/plastic crystals
• Not sapphire glass — mineral glass is the correct replacement for watches originally fitted with mineral crystals
