INSPIRATION
Tandberg
- A tribute to the past, made for the future
When Norway was in the midst of the post-war technological boom, few names symbolized quality and innovation quite like Tandberg. Now, decades later, Von Doren breathes new life into this story with its latest launch: "Tandberg." The watch is a unique tribute to Norwegian craftsmanship, timeless design and pioneering spirit - and marks a meeting between past and future.

Vebjørn Tandberg: A pioneer in Norwegian industry
The name Tandberg evokes strong memories for many. Vebjørn Tandberg was more than an engineer; he was a visionary, and his vision was to create the perfect product. In the 1950s and 60s, Tandberg products were known far beyond Norway's borders, and many of his innovations set the standard for both sound quality and design. It is precisely this combination of functionality and design that has inspired Von Doren's latest creation.

The design that tells a story
Founder Øyvind Von Doren received his first Silver Super 10-72 as a boy and has been an avid collector of Tandberg products ever since. The watch has been under development for almost three years, and in February 2023, Von Doren was granted the Tandberg trademark for mechanical watches by the Norwegian Patent Office.
