About this entry
80% of key specs known. Missing: hardening, AR coating, bracelet offered.
Bronze Fifty Fathoms MIL-SPEC-style diver with a humidity indicator at 6 (湿度计, "hygrometer", in the SKUs). Sold in Thorn's regular listing at $209 with or without logo (in stock on 2026-10-25, listed since January 2024) and in a "Clearance Deal" listing, whose prices are entered as sale prices: $50 with logo and $166.32 without (both crossed out from $189); both clearance options were sold out on 2026-10-25. Both listings give the model as "Thorn SHY039" and the same specs; the bronze no-radiation-emblem version is the SHY038. Brand specs: Japan NH35A automatic, CuSn8 tin bronze case, 316L screw-down caseback, 120-click unidirectional ceramic bezel, domed sapphire, 200m, Swiss C3 green lume, screw-down crown, 40mm without crown, 50.4mm lug-to-lug, 14.2mm including the crystal, 20mm band, 78g including the band. The photos show a striped nylon strap (not described) and no date window, so the NH35's date is recorded as hidden. AR coating is not stated. The clearance listing went up on Thorn's store in April 2026.
