About this entry

73% of key specs known. Missing: lug-to-lug, weight, hardening, AR coating.

Titanium Tuna-style shrouded diver with a GMT hand (钛罐头, "titanium tin can", the Chinese nickname for the Seiko Tuna, in the SKU). Its image files are named "T013", but they show this 47mm titanium GMT, not the published 36mm T013. Brand specs: Japan NH34 automatic, Grade 2 titanium case and caseback, sapphire crystal, 120-click unidirectional bezel with a two-tone aluminium insert and BGW9 lume dot at 12, Swiss C3 Super-Luminous / vintage lume, screw-in crown, 22mm genuine leather strap, 200m, 47mm, 14.8mm including the crystal. The size list gives a "band width" of 12mm, taken as a typo for the 22mm strap width stated above it. The compass (degrees and cardinal points) bezel scale and the date window are from the photos. Lug-to-lug, caseback attachment and AR coating are not stated. Price 09 (crossed-out 19); sold out on 2026-10-25. First listed on Thorn's store in March 2025.
