Nomos Glashutte Watch Tangente 33 Champagne Steel Back 150. As straightforward and refined as ever, now with a special shine, Tangente 33 champagne. 33 denotes the diameter size, which is somewhat smaller; champagne is our name for the color of the dial, which is borrowed from the tone of the neomatik watch models. But within this timepiece ticks manual caliber Alpha, hidden from view beneath the stainless steel back, which offers ample room for an engraving of a pledge, a wish, or a telephone number.
