About this entry
79% of key specs known. Missing: weight, hardening, end links, clasp micro-adjust.
Time-only three-hander from the 1956 collection (named for the 1956 Cortina Winter Olympics). Brand specs: Sellita SW200-1 elaboré (26 jewels, 41h), 40mm, 46mm lug-to-lug, 11.9mm, 100m, screw-down crown, ultra-domed sapphire with double internal anti-reflective coating, fixed ceramic bezel with lumed markers, closed 316L caseback engraved with the collection logo (fitting not stated). The dial has no date window, so the SW200-1 is used without its date. Lug width (20mm) is from the authorized retailer SeriousWatches, not the brand. Lume: Old Radium Super-LumiNova (glows green) on the bezel markers and hands of the Black and Khaki, BGW9 (glows blue) on the Warm Gray. Every watch comes on a black tropical rubber strap plus a second strap of the buyer's choice, or the 316L 1956 bracelet for €50 more. The bracelet has screw links and comes with an extra one-and-a-half link; its links per row are counted from the brand's photo, and the clasp isn't described. The brand says the bracelet fits only 1956 3H watches with "323XXX" serial numbers, not older "1956-XXXX" ones, so there are at least two case generations; the store listing dates back to 2023 and earlier specs may differ. Weight not published.
