The DUW 5201 is an automatic movement with world time from Nomos. It is an evolution of its predecessor, Nomos Xi, and was introduced in 2014. DUW 5201 was the first automatic movement to use Nomos' in-house Nomos Swing System.
The 2005 introduction of the Alpha movement family was an important turning point for Nomos. Although based on the preceding Nomos 1 TSP, it was largely constructed in-house rather than being a refinished ebauche. This was followed in 2006 by the Nomos Epsilon, the first Nomos movement with automatic winding. The next great leap forward for Nomos was the 2014 introduction of the Nomos Swing System, an in-house assortment, in movement DUW 4401. Over the next few years, this technology moved to other models in the Nomos movement family, including the first automatic Swing System movement, DUW 5201.
Introduced in 2014, the Nomos DUW 5201 movement is an automatic movement with small seconds at 6 00 and a world time wheel. Like other Nomos movements, it is made in a three-quarter plate design, plated with rhodium and decorated with Glashütte ribbing and perlage. The ratchet and crown wheels are decorated with a Glashütte sunburst pattern and blued screws are used. It features Glashütte stopwork, Incabloc shock protection, and 26 jewels.
The world time mechanism adds substantial thickness to similar movements, as does the automatic winding mechanism. However, Nomos moves much of the components to the periphery of the movement, trading width for depth. For this reason, the movement measures 31 mm in diameter and 5.7 mm thick.
Calibre DUW 5201 replaced the Nomos Xi movement, with which it shares many components.
This movement is part of a family of Nomos movements produced since 2014. The movement is made in-house, including the Nomos Swing System.
