About this entry

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

A turtle-case diver (the SN047-G-R listing title calls it a "6105 Diving Watch", hence the Seiko 6105 reference) sold in three listings that share the NH35 and the 44mm case: SN047-G-B (hexagon logo, ceramic bezel; $230 on bracelet, $210 on rubber or leather strap) and the older SN047-G (leather strap) and SN047-G-R (rubber strap), both $209, each colour with or without logo at the same price. The steel-case specs above are from the SN047-G-B listing: "NH35A", 316L, 44mm, 47.5mm lug-to-lug, 14mm (not stated whether that includes the crystal), 20mm lugs, slightly domed sapphire with AR coating (side not stated), 120-click unidirectional ceramic bezel with lumed 12 o'clock marker, sunray blue or green dial with applied hexagon logo (a black dial is also offered), "SLN C3" green lume on hands and markers, screw-down crown, screw-down caseback with pressed 3D shark, solid 316L bracelet 20mm tapering to 16mm with a "new folding clasp with safety" (micro-adjust not stated), 200m, about 171g (not stated what was weighed). The SN047-G and SN047-G-R listings quote 44mm without crown, 47mm lug-to-lug and 13.5mm including the crystal, which is within San Martin's hand-measuring spread of the SN047-G-B figures, so they are treated as the same case; they say "Swiss shadowless anti-reflective film", "C3 Super Luminous", screw-in crown and caseback, a sunburst blue or green or matte black dial with an applied SANMARTIN logo, and about 115g on strap, and don't describe the bezel. Both older listings say the model "will automatically change to the new case" once the current cases are sold out. The SN047-G listing is titled "with leather strap" but its spec list repeats "Silicone rubber strap" from the SN047-G-R listing; the leather strap is recorded from its title and photos. The 60-minute bezel scale is from photos; all dials show a date at 3. The bronze SN047-B-Q is in sn047-bronze. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
