Tangente Gangreserve by Nomos Glashuette

A very practical (and, unfortunately, sometimes underappreciated) function keeps you from forgetting that this is a hand-wound watch. Just like a car’s fuel gauge, the patented power reserve indicator shows when the caliber is running down. The mechanism was integrated in the barrel, ensuring that the watch remains flat and elegant. With the NOMOS Gamma movement, visible through the sapphire crystal glass back.
