Rastarkalv
A watch for the ages – raw Norwegian nature and premium Swiss Made quality combined. The RASTARKALV dial is 3,300 years old, made from a root extracted from the swamp at Rastarkalv, Frei. Refined into a limited edition of 47 uniquely numbered dials set inside our Straum 316L Damascus Steel watch case, protected by the double-domed Sapphire glass with internal AR coatings, surrounded by the stainless steel sunburst and polished bezel. The Sapphire back reveals the Swiss-made Sellita SW-200-1 movement. Diamond-cut hands and indexes with Superluminova BGW9. Complete with a vegetable-tanned full grain leather strap with a custom Straum buckle.
