About this entry
84% of key specs known. Missing: hardening, end links, link attachment.
Shrouded diver that the store calls "Tuna", after Seiko's Tuna; the shroud is held by screws (product photos). Brand specs: "Japan NH35 automatic, 41 hours of energy storage", 316L case and caseback, 120-click unidirectional aluminium bezel, sapphire crystal with AR coating (side not stated), "Swiss C3 green and BGW9 blue" lume, screw-down crown (7mm), screwback case, 300m, "Bezel diameter: 41mm", "Case length: 44.5mm (lug to lug)", 15mm, 22mm lugs, 203g. The brand gives only a bezel diameter, which is recorded as the diameter; the shroud is wider than the bezel in the photos and its width is not stated. Whether the 15mm includes the crystal is not stated. The brand doesn't say which dials get C3 and which BGW9; the lume photo of the white version glows blue. The dimension graphic shows the watch on its bracelet (220mm) with 203g, so the weight is recorded as on the bracelet. The solid engraved caseback, the three-link bracelet and the fold-over clasp with safety lock and spring-bar micro-adjust holes are from the photos; the listing doesn't describe the bracelet. Bezel scale and colours are from the photos. All four colours $149 with no crossed-out price; Green was sold out on 2026-10-21. Shares the 41mm / 44.5mm / 15mm / 22mm / 300m figures with the AD2098, which has a ceramic bezel insert and a double-domed crystal.
