NOMOS Glashütte

Tetra 27 DUO White Square Dial Hand Wound Watch

The Tetra 27 DUO – 405 brings Bauhaus minimalism into a perfectly balanced square form. Measuring 27.5 × 27.5 mm, this elegant two-hand timepiece is designed for more slender wrists, with golden hands set against a white silver-plated dial for a warm, understated look. Refined and precise, it offers a fresh interpretation of NOMOS Glashütte’s classic design language.

Crafted in stainless steel with a sapphire crystal glass front and a stainless steel back, Tetra 27 DUO is slim at just 6.1 mm in height. Its geometric proportions and clean lines highlight the purity of its design, while the beige vegan velour strap adds a soft, contemporary finish. Water-resistant to 3 atm, it is as practical as it is stylish.

At its heart is the NOMOS Alpha.2 calibre, a hand-wound movement based on the renowned Alpha but specially adapted for two-hand models. With a height of only 2.6 mm, 17 jewels, and a power reserve of up to 43 hours, Alpha.2 is as reliable as it is precise. Crafted in Glashütte and richly decorated in the traditional style, it ensures that the Tetra 27 DUO – 405 is not only a design statement but also a watch of enduring horological quality.
