Crystals

About

Sapphire sits just below diamond for scratch resistance, which is why every crystal here is sapphire — most with double-sided anti-reflective coating available for a clearer view of the dial. Two profiles to choose from: flat, for the low, original-style look, or double domed, where the top and underside both curve and catch the light with a vintage character. Cut for SKX007 and SKX013 mods, plus a 30mm double domed option for Seiko 5 SNK builds. Every product page lists the exact models each crystal fits.
