In a watchmaking world where round watches largely dominate the landscape, certain creations fully embrace their difference. This is the case of the Tetra by NOMOS Glashütte, whose geometric lines and minimalist elegance have embodied a singular vision of German watchmaking for over thirty years. In 2026, the Saxon manufacture enriches this emblematic collection with two new references: Tetra 27 white and Tetra 27 duo.
Compact, refined and powered by manual-winding in-house movements, these new models once again demonstrate that watchmaking sophistication does not depend on the size of a watch, but on the precision of its design and the coherence of its style.

A square watch that became a NOMOS signature

Since its creation, the Tetra has occupied a special place in the collections of NOMOS Glashütte. While most timepieces favour round cases, the German manufacture here asserts a perfectly balanced square architecture, which has become one of the signatures of its identity.
Its stainless steel case, with particularly harmonious proportions, is enhanced by fine double-stepped lugs whose lines subtly evoke Art Deco aesthetics. This construction gives the Tetra an immediately recognisable personality, both contemporary and timeless.
With sides measuring just 27.5 millimetres, the new Tetra 27 models are among the most compact in the entire NOMOS catalogue, without ever giving the impression of being mere miniature watches.
Proof that Haute Horlogerie does not depend on diameter

In a market where generous dimensions have long been the norm, NOMOS takes a decidedly different approach.
The new Tetra 27 models are a reminder that the demands of Haute Horlogerie lie above all in the quality of the movement, the care given to finishing and the precision of every component.
Both models are powered by mechanical manual-winding calibres entirely developed and made in Glashütte, the historic cradle of German watchmaking. Offered with a transparent sapphire caseback, they allow the movement and its meticulous architecture to be admired, true to the finishing standards that have made the manufacture’s reputation.
Tetra 27 duo: the art of returning to the essentials

With the Tetra 27 duo, NOMOS pushes its minimalist philosophy even further.
The silvery white dial stands out with a composition of remarkable sobriety. A light grey square occupies its centre while a second grey frame discreetly outlines the minute track, creating a subtle interplay of perspectives that echoes the geometry of the case.
The display is deliberately reduced to the essentials: only the hours and minutes are indicated, by two flame-blued hands whose deep hue contrasts elegantly with the clarity of the dial.
Inside beats the in-house calibre DUW 4001 duo. Equipped with the proprietary NOMOS Swing System escapement, it offers approximately 53 hours of power reserve while guaranteeing the precision that characterises movements developed by the Saxon manufacture.
Tetra 27 white: small seconds with elegance

The Tetra 27 white takes up the same case architecture while offering a slightly more classic interpretation.
Its silvery white dial hosts a small seconds subdial perfectly integrated into the lower part of the composition. The minute track plays with geometric shapes, subtly combining the circle and the square, while a discreet point placed at six o’clock reinforces the graphic balance of the whole.
As on the duo version, the flame-blued hands bring a touch of colour that underlines the watch’s artisanal character and recalls one of the most emblematic traditions of German watchmaking.
A collection that keeps growing

With these two new models, NOMOS continues to develop the Tetra 27 family, which now includes several sizes, different dial configurations as well as versions in stainless steel or 18 carat gold.
This diversity allows the collection to meet varied sensibilities while retaining a particularly strong visual identity. Whether chosen for its unusual design, its discreet elegance or its in-house movement, the Tetra remains one of the most original proposals in the contemporary watchmaking landscape.
German elegance in its purest expression

Through the Tetra 27 white and Tetra 27 duo, NOMOS Glashütte reminds us that modernity can be expressed with restraint. Far from fleeting trends and spectacular displays, these two new references favour balanced proportions, mechanical quality and purity of design.
An approach true to the spirit of the German manufacture, which continues to uphold a demanding vision of watchmaking: one where every detail has a function, where every line contributes to the overall harmony, and where true sophistication lies in perfectly mastered simplicity.
