Character, squared.
The NOMOS Glashütte Tetra Ref. 406 gives classic watchmaking a distinctly geometric expression, pairing its 29.5 mm square case with a clean silver-plated dial and tempered blue hands. Beneath its unconventional form, the hand-wound manufacture movement embodies the precision and traditional craftsmanship of Glashütte.
We carry it for collectors who appreciate design with conviction — where distinctive geometry, mechanical refinement and timeless German watchmaking come together.

A hand-wound calibre defined by Glashütte tradition.
The DUW 4001 is a manually wound manufacture movement combining traditional Glashütte architecture with NOMOS’ proprietary engineering. Its three-quarter plate, Glashütte stopwork, tempered blue screws and finely decorated surfaces are complemented by the NOMOS Swing System and DUW regulation system. Regulated in six positions with a 53-hour power reserve, it reflects NOMOS’ commitment to precision, reliability and meticulous finishing.
