About this entry

93% of key specs known. Missing: hardening.

The NH35 automatic with centre seconds; the NH35 has a date but the photos show no date window, so complications are time only. Sold in the SN0117-G listing as "Dial B with NH35 Movement" (spec list "SN0117-G-A/B"); the ST3621 hand-wound version (sn0117-st3621), quoted at 13.2mm, is a separate model. Brand specs: 316L stainless steel, 41mm, 50mm lug-to-lug, 11.5mm (not stated whether that includes the crystal), 22mm lugs, sapphire with AR coating (side not stated), black Type B flieger dial, blue-plated luminous hands, BGW-9 blue on hands and markers, push-pull onion crown, circular-brushed screw-down caseback, quick-release leather strap 22mm tapering to 18mm with a 316L steel logo buckle (no bracelet offered), 100m, about 81g (not stated what was weighed; the same figure is given for steel and bronze). inspired_by is read from the design (Type B observation-watch dial with triangle and dots at 12); the brand does not name it. The store files the listing under both its SN0117 and SN030 categories; the SN030 models are a different code. See also the bronze SN0117-Q (sn0117-bronze-nh35, sn0117-bronze-st3621). Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
