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 Glashütte. From today until December 25—while stocks last—we are giving you another beautiful timepiece of protected origin with the purchase of this Tetra: an hourglass made of Murano glass.
