NMK922 SRPE Watch Case: Polished Finish


Get 20% off any bezel with the purchase of a watch case! Use discount code BEZELBUNDLE during checkout.

Love the look of the SKX but wished it was a little less bulky and more versatile? Meet the SRPE, the SKX's younger cousin and Seiko's answer to a smaller and sharper looking watch that looks great with a pilot bezel (or just about other bezel really - check out our SRPE bezel options here). At 40mm, this versatile case will look great as a Pilot watch, or a Field watch, or a Tool watch…you get the drift.

Designed to fit screw-down crowns for better water resistance, and all other SRPE mod parts, the NMK922 SRPE Watch Case will make a great base for a whole bunch of build options.

Small Explorer?

This was another test case for me. I wanted something a bit dressier, and not bulky. Other than the bracelet, this is all Namoki--case, dial, hands, and chapter ring. I'm having some issues with the caseback gasket, but I'm sure I will be able to resolve them. I think this is a great-looking case for a host of different builds where you don't want a "dive watch".

A great case for aviation builds.

I got this case bundle just to test out for myself how it is to build with. This is a very easy case to put together into a finished project. So long as you remember SRPE crystal and chapter ring, and not SRPD, everything fits and there isn't a lot extra that the assembler needs to do.

Hilariously fun case

This excellent Namoki case was a build on a whim. I really like how it turned out. Beautiful, perfectly machined, quality parts as always.

Question About Crown

Is this an SKX crown? Will the case fit a standard SRPE crown?

This case need an skx chapter ring or an srpe chapter ring? Thanks
