Nomos Glashütte's square watch "Tetra" now has two new models: the "Tetra 27 White" and the "Tetra 27 Duo." The existing models, which previously had a solid back, now feature a see-through back, allowing the in-house hand-wound movement to be admired from the back of the square case.
The new "Tetra" model allows you to enjoy the charm of a classic design, even through its see-through back.
Nomos Glashütte has added two new models to its Tetra series of square watches: the Tetra 27 White and the Tetra 27 Duo. The Tetra, a line that has been around since the brand's inception, is a dress watch collection characterized by its silver-finished dial, blued hands, and minimalist square case. With lugs that have a stepped edge on the sides, the design evokes the heyday of Art Deco when square watches first appeared.
The "Tetra 27 White" features a simple design with a silver-plated dial and a small seconds subdial. The strap is made of Horween shell cordovan leather. It has a manual winding movement (Cal. DUW 4001), 17 jewels, and a power reserve of approximately 53 hours. The case is stainless steel (27.5mm x 27.5mm, 6.1mm thick). It is water-resistant to 5 atmospheres. Price: 418,000 yen (including tax).
The new models are all based on the original "Tetra 27," but with modified dials. The Tetra 27 White features a silver-plated dial with a small seconds subdial, blued hands, black typography, and a dot at the 6 o'clock position as accents.
On the other hand, the Tetra 27 Duo is a two-hand model that omits the small seconds subdial. The dial is white silver plated, while the center and minute markers are light gray, creating a two-tone finish. This difference in texture is achieved through sandblasting.
The "Tetra 27 Duo" features a two-hand design and a sandblasted two-tone dial. It has a manual-winding movement (Cal. DUW 4001 Duo), 17 jewels, and a power reserve of approximately 53 hours. The stainless steel case measures 27.5mm x 27.5mm, with a thickness of 6.1mm. It is water-resistant to 5 atmospheres. Price: ¥369,600 (including tax).
The stainless steel case is a minimalist 27.5mm wide, yet boasts a water resistance of 5 atmospheres, sufficient for everyday use. The Tetra 27 White is equipped with the Cal.DUW 4001 movement, while the Tetra 27 Duo features the Cal.DUW 4001 Duo. Both models allow you to admire the Côtes de Genève decoration and the beating balance wheel through the transparent case back.
In addition, to coincide with the release of these new models, the original Tetra 27 and the "Tetra 27 Duodore" have also been updated with models featuring a see-through back.
The existing "Tetra 27" model now also features a see-through case back, allowing you to admire the movement. It's a hand-wound movement (Cal. DUW 4001), with 17 jewels and a power reserve of approximately 53 hours. It has a stainless steel case (27.5mm x 27.5mm, 6.1mm thick) and is water-resistant to 5 atmospheres. The price is 418,000 yen (including tax).
The "Tetra 27 Duodre" now also features a see-through case back. Gold-colored hands and a vegan velour strap create a soft and elegant look. Manual winding (Cal. DUW 4001 Duo). 17 jewels. Power reserve of approximately 53 hours. Stainless steel case (27.5mm x 27.5mm, 6.1mm thick). 5 ATM water resistance. 369,600 yen (tax included).
