SKX Slim Caseback: Brushed Black Finish


This product is unavailable

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 10 ATM. 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: 100m


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.

Not much to say. It's a very nice fitting caseback with a good finish. High quality part

Great option for slimming down SKX based cases (but not the SSK)

Great quality, but note, this does not fit the new NH34 SSK GMTs straight out of the box (you may need to replace the movement holder as it won't screw down the whole way)

Built an SKX013 diver from scratch for my partner’s birthday. The slim caseback really helps to keep the bulk down. She loves the watch!
