Nomos Glashutte Watch Tetra Aubergine Sapphire Crystal 475. In bold aubergine, Tetra signals self-confidence. The luxurious rose gold of the small seconds dial adds an epicurean flair, while the turquoise second hand demonstrates a sense of humor. With a velvety gray strap made of vegan velour, the hand-wound watch with the manufactured Alpha caliber lies softly against the arm. Valuable and precise shaped by the unique art of watchmaking from Glashutte.
