SKX Slim Sapphire Caseback: Polished Finish


This product is sold out

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 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.

I Love These Casebacks!

Seriously, these things are great! All the functionality and looks of a display caseback but without a lot of the thickness that they usually come with. Granted, it lowers the WR to 100m but with that and the crown screwed down, it’s more than enough for almost all watch folks. Get yourself one!

SKX Caseback: PVD Matte Black Finish

Does not match the case

The color is more of a gun metal or dark grey as compared to the PVD black of the Capt. Willard case I ordered with it. It has a contrast against the case that I was not looking for. The finishing, fitment and overall quality are top notch and what I expect when I order form Namoki. Since it is a case back for a personal build, I am not terribly worried, but I just wanted to let other customers know.

Namoki Has Superior Parts

Never a problem with fitment on mechanicals. That’s a big plus and saves time.

Excellent Upgrade

This is an excellent upgrade to show off your hard work. Pair it with an upgraded movement rotor for that polished finish.
