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.

GMT watch build

Case is superb and sturdy. Used for a GMT build. Love the black PVD coating. Just check the results... Thanks Namoki

Nice case

In some points I like this case more than original. In first place screw-down crown. Well made and PVD coating is great.

Good case with a few issues

The case looks very nice. I like the added screw down crown. Unfortunately, there are some issues with the description and fit. The listing says it comes with Fat Spring Bars (same as SKX) but it does not, making watch band selection more difficult. The caseback gasket seems to be the SKX style one instead of an SRPE one which doesn't allow the caseback to screw down all the way. Lastly, not really an issue but I'm curious about the screw down crown compatibility if I ever needed a replacement.
