About this entry

80% of key specs known. Missing: weight, hardening, bracelet offered.

Limited edition launched in 2021 alongside the first Opphav: 47 uniquely numbered dials cut from a 3,300-year-old root pulled from the swamp at Rastarkalv, Frei, in a Damascus steel case. Straum: "Straum 316L Damascus Steel watch case", double-domed sapphire with internal AR coatings, stainless steel sunburst and polished bezel, sapphire caseback showing a Swiss Sellita SW-200-1 (grade not stated), diamond-cut hands and indices with Super-LumiNova BGW9, vegetable-tanned leather strap with a custom Straum buckle. Straum's product photo shows a date window at 3, unlike the Opphav models. Kept as its own model because Straum sells it under its own name its dial shows a date, and its movement grade is not stated (the Opphav Damascus has an Elaboré movement without the date). Straum gives no dimensions; Fratello says the 2022 Opphav Damascus uses the Rastarkalv's Damascus case and is otherwise the same watch as the Opphav, so the Opphav case figures from Watch Clicker (41mm, 46.6mm lug to lug, 11.1mm, 22mm lugs, push-pull crown with crown guards, 100m) are recorded here as carried over, not measured on a Rastarkalv. Sold out; the archived page (tagged "Discontinued") still lists $1,800.
