Stefan is a master watchmaker and has been plying his trade for well over a decade in his native Germany. He is perhaps best known for his fantastic skeletonised watches, which he hand cuts using the classic way, a jewelers saw, to create his horological works of art. He creates small numbers of watches per year, and has recently designed and made his first non-skeleton Time Only watch, the Kudoke 1 with his own designed caliber, based on the Habring2 Felix, with several modifications and his hand finishing. In 2019 he revealed the Kudoke2 with the Day/Night or 24hr dial at 12 o'clock.
