SKX Slim Sapphire Caseback: Rose Gold Finish



Sapphire display casebacks are usually quite a bit thicker than normal steel ones in order to maintain the same level of water resistance. We've designed a Slim Sapphire Caseback in Rose Gold Finish that's 52% thinner (1.2mm vs 2.5mm!) than our normal Sapphire Caseback for the modder who wants to appreciate their movement and still want their watch to be as thin as possible.

Be sure to also check out our range of rotors for that sweet c-c-combo!

Caseback Specifications:
Thickness: 1.2mm
Water Resistance: 100m


Fits Seiko NH movements (like the ones that we sell) with a Grey Spacer only.

Great finish

This was a great product to finish my gold skeleton project for a NH71 watch that is a little dressy. I rarely place display caseback, but wanted to utilize for his time. This was a nice one that worked with the other case that I used from Modmode. Great caseback would buy again.
