About this entry

74% of key specs known. Missing: hardening, bracelet links, end links, link attachment, clasp micro-adjust.

Two listings sell the same NH35 diver with identical specs: the SN085-G on a solid five-link bracelet ($258) and the newer SN085-B on a solid mesh bracelet ($288), each with a black dial and red bezel or a grey dial and orange bezel. The SN085-B title says 39.5mm but its spec text says 40mm, like the SN085-G; the spec figure is recorded. Brand specs: 316L, 40mm, 48mm lug-to-lug, 13.5mm (not stated whether that includes the crystal), 20mm lugs ("lug to lug width"), sapphire with AR coating (side not stated), 120-click ceramic bezel with lumed 12 o'clock marker (direction not stated), enamel dials with a 3D hexagon applied logo, BGW-9 blue lume on hands and markers, screw-down crown with 3D "S" logo, screw-down caseback with stamped shark, folding clasp with safety (micro-adjust not stated), 200m, about 164g (not stated what was weighed). Photos show no date window, so complications are time only. The SN085-B was in stock on 2026-10-25; the SN085-G showed "Out of stock".
