story

Rastarkalv

The story of the 3,300 year-old root extracted from swamps on the plains of Rastarkalv on the island of Frei, and the viking battle in year 955.

Explore story

3300 year-old dial

3,300 years ago, a pine fell into a swamp on the plains of Rastarkalv – a place that would come to be known as Norway. 2,400 years passed before the Viking kings of Norway and Denmark clashed in battle in the very same place. As the battle roared above, the tree witnessed the bloodshed from the depths of its silent grave. Shrouded in darkness and deprived of oxygen, it was preserved in perfect condition. After extracting the wooden piece from the swamp, it has been refined into 47 uniquely numbered dials.

Case back

The case back is adorned with a stamped and surface-treated 3D motif capturing the battle of Rastarkalv. Two sapphire crystals windows provide a clear view of the beating heart of Rastarkalv, the Sellita SW-200 movement.

Damascus steel case

By forging layers of steel with different characteristics, the Vikings crafted swords with superior strength and flexibility. The watch case of Rastarkalv has been forged with the same method. A final acid treatment brings out the unique pattern of each watch case.

Radiocarbon dating certificate

Radiocarbon dating determines the age of organic material by measuring the remaining radiocarbon (14C). The age of the Rastarkalv root is estimated and verified by the Poznan Radiocarbon Laboratory, and all Rastarkalv watches come with a carbon dating certificate confirming the age.

Leather Strap

Made from beautiful full grain vegetable-tanned leather, and a matching liner leather of the same quality. The strap is designed to perfectly fit Straum watch cases at 22mm lug width, with the inset lug cuts and a slight padded profile on the top half of the strap. Medium weight stitching round the edge completes the look. The strap also includes the custom Straum buckle. All versions feature quick-release spring bars for easy fitting.
