About this entry
79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.
Same 38.5mm, 47.2mm lug-to-lug SN0105 case and NH35 as the SN0105-G (see sn0105-nh35), but with a top-hat sapphire crystal instead of K1 mineral glass, so it is kept as its own model; its 12.3mm thickness against the SN0105-G's 11.9mm is consistent with the taller crystal. Brand specs: 316L, 38.5mm, 47.2mm lug-to-lug, 12.3mm (not stated whether that includes the crystal), 20mm lugs, top-hat sapphire with AR coating (side not stated), light yellow dial with printed 3D indices and a printed red 12, baked-varnish blue hands, retro C3 green lume on the logo and markers, push-pull crown with 3D hexagon logo, brushed screw-down caseback, "7 Links" solid 316L bracelet 20mm tapering to 18mm (beads-of-rice in the photos) with a folding clasp with safety, 100m, 125g (not stated what was weighed). No micro-adjust is mentioned. Sold with or without logo at $288. The NH35 has a date but photos show no date window, so complications are time only; the solid caseback and fixed bezel are from photos. On 2026-10-25 the version with logo was in stock.
