NMK960 Sumo SKX007/SRPD Case: Steel Finish

The NMK960 Sumo SKX007/SRPD Case in Steel Finish taps into one of Seiko’s most beloved modern diver silhouettes—the “Sumo,” nicknamed for its broad shoulders, rounded flanks, and chunky yet surprisingly wearable proportions. It's a big, purposeful dive case that still hugs the wrist and doesn’t feel like a brick. This case carries over those trademark flowing case sides and strong lugs, giving your build that instantly recognizable Sumo stance while staying fully SKX-compatible under the hood.
