SKX Slim Caseback: Brushed Black Finish


The SKX is a chunky watch alright - if you ever wished you could reduce the overall thickness of the SKX, this slim caseback is perfect for you!

Our SKX Slim Caseback is a whopping 55% thinner (0.8mm vs 1.8mm) and 40% lighter (9g vs 15g) than our standard SKX caseback, and is rated to a water resistance of 5ATM. We have tested it ourselves with a 6ATM water pressure tester with no issues whatsoever. Not appropriate for actual diving - but it'll do great for desk diving, swimming pools, and showers. What, you don't shower with your watch on?!

Caseback Specifications:
Thickness: 0.8mm
Water Resistance: 50m

Compatible with SKX007/009, SKX013, and all the SKX-style cases that we sell on our website.

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

Great addition for lower profile builds/mods

Have used both the black and brushed versions, and love them both! Only questions are what took so long, and will you do it in Titanium too??

Great new caseback's

Loving the slimmer profile of the new casebacks, the really help with the overall height of the total watch. I have used in both black and brushed/polished stainless. They provide a bigger footprint for caseback engraving too.

Very thin. Put in on my long island watch that has same specs as skx 013. Worked perfect.
