Homage of the Seiko 6105-8110 worn in Apocalypse Now. This file follows the SD1970C listing (black dial, ceramic insert, "super luminous"): 43.8mm, 46.8mm "case length" (lug-to-lug), 13.5mm, 20mm strap, sapphire with "transparent AR coating" (side not stated), ceramic 120-click unidirectional bezel, NH35 (24 jewels, 21,600 vph, hacking, ~41h), 200m, sold on a rubber or khaki nylon strap with a free extra strap. The page lists "96g without strap / 203g with bracelet"; the identical line appears on the SD1953 page, so the figures may be boilerplate, and the 203g bracelet figure is not recorded because the SD1970C is not sold on a bracelet. Case grade 316L, Super-LumiNova on indices, hands and bezel, and the 46.8mm lug-to-lug are confirmed by an owner review of a blue SD1970, which also says the standard three-link bracelet has a milled clasp, that V2 versions add micro-adjustment, and that bracelet quality varies. Crown type, caseback and lume grade are not stated by the brand. Other SD1970 versions on the official store: SD1970F (green, blue, brown and other dials, $134-149.90), SD1970X black case ($159) and SD1970 on a nylon strap ($133).
