It is the watch of choice among architects and writers, a multiple prizewinner, and the iconic NOMOS timepiece: Tangente. With clear lines and perfect proportions, tempered blue hands on a white silver-plated dial, a strap from Horween Genuine Shell Cordovan. And of course—the hand-wound NOMOS Alpha caliber, visible through the sapphire crystal glass back; a classic itself.
