Introduction
Founded in Glashütte in 1990 following German reunification, Nomos has established itself as one of Germany's most respected modern watchmakers through its distinctive Bauhaus-inspired design language and accomplished in-house movements. In 2022, to celebrate 175 years of watchmaking in Glashütte, Nomos released a special series of four limited-edition Tetra Neomatik models, each produced in just 175 examples and distinguished by its own dial colour.
The present reference 421.S3 is the blue execution from the series, bringing a rich and unusually expressive colour to the Tetra's disciplined square architecture. Housed within the distinctive 33mm stainless steel case and powered by Nomos' ultra-thin in-house DUW 3001 automatic calibre, it combines the playful use of colour seen throughout the anniversary collection with the restrained proportions and clean typography that have long defined the Tetra.

THE DIAL
Reference 421.S3 is distinguished by its rich blue dial, bringing considerably more colour to the Tetra's otherwise restrained design language. Nomos' characteristic Arabic numerals, fine minute track and small seconds display at 6 o'clock retain the clarity and graphic precision of the original Tetra while giving this anniversary edition an immediately recognisable identity.
THE CONSTRUCTION
The polished 33mm square stainless steel case remains one of Nomos' most distinctive designs, wearing considerably larger than its dimensions suggest thanks to its 45.3mm diagonal measurement. At only 7.3mm thick, it maintains an elegant profile despite housing an automatic movement, while its elongated lugs reinforce the architectural character that has defined the Tetra since its introduction.

Our Perspective
The Tetra has always demonstrated how effectively Nomos can combine strict geometric design with a playful approach to colour. Limited to just 175 examples in celebration of 175 years of watchmaking in Glashütte, the blue ref. 421.S3 adds genuine rarity to that formula. Together with the accomplished DUW 3001 manufacture calibre, it makes for a particularly appealing expression of modern German watchmaking.
