The Nomos Glashütte Tetra watch is truly amazing, a square watch with a serious attitude. Designed for the contemporary watch lover who enjoys their watch with a splash of cool about them. Created using the best materials and created by the design team, the Tetra is one of the most incredible watches in the NOMOS collection and it is not difficult to see why this has been so. Tetra is a great Glashütte timepiece: simple, clear, perhaps rather selfish even.
