Upgrading your crystal from stock Hardlex glass to a premium Sapphire Crystal is a great first mod for your Seiko 5 Sports SRPE. This NMK351 SRPE Flat Sapphire Crystal is designed to be the perfect replacement if you like the original flat Hardlex but want to upgrade it to a much higher quality sapphire crystal.
Our sapphire crystals have Anti-Reflective (AR) coating at the bottom side of the crystal. The AR coating comes in two colours - Blue and Clear AR.
