About this entry
80% of key specs known. Missing: weight, hardening, AR coating.
Automatic chronograph in the Averau Ceramic case: 42mm matte black ceramic around a Grade 2 titanium frame (TiFrame), with a closed Grade 2 titanium caseback engraved with the collection logo and an individual serial number. Brand specs: Sellita "SW510B-1" automatic elaboré (27 jewels, 56h), 42mm, 51.5mm lug-to-lug, 14.6mm, 100m, screw-down crown, domed sapphire (AR coating not stated). Sellita has no SW510B-1; its SW510 b is the automatic tricompax without date, which matches the dial (small seconds at 9, 30-minute counter at 3, 12-hour counter at 6, no date window), so movement.id is the SW510. The 56h the brand quotes is Sellita's minimum power reserve (typical 62h). Tachymeter scale on the dial flange. Lug width (20mm) is from the authorized retailer SeriousWatches. BGW9 Super-LumiNova (glows cyan) on the main indices and the hour and minute hands. Sold only on straps at one price. The black version was listed in September 2025; the Sand dial was added in August 2026 and was on pre-order on 2026-10-25. The "Amaranth" (Archive 02) is a one-of-a-kind piece with amaranth red indices and hands, sold on 3 July 2026; its page still loads. Weight not published.
