NMK303 - SKX/SRPD Top Hat Sapphire Crystal



This NMK303 - SKX Top Hat Sapphire Crystal evokes a vintage style reminisce of the dive watches of the 1950s and 60s. Flat at the top and curved at the sides, it catches the light brilliantly and is perfect for any vintage styled mods. We designed this specifically to have a slightly lower profile for those who don't like their top hats protruding out too high. It looks better (to us), plus the lower height means it's less likely you're going to bang your watch crystal against something.

Our top hat sapphire crystals have Anti-Reflective (AR) coating at the bottom side of the crystal. The AR coating is available in two colours - Blue and Clear AR.

Compatible with SKX007, SKX009, SKX011, SKX171, SKX173, SKX175 and Seiko 5 Sports SRPD Range.

Fits all our SKX Flat Inserts.
