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.
Nomos introduced the Nomos Swing System slowly, beginning with hand winding movements and the slower-selling world time DUW 5201. Only once production had ramped up in 2017 did Nomos bring the Swing System to a mainstream automatic movement, DUW 5101, and two more years before DUW 5001. This automatic movement has small seconds at 6:00 but no date 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.
Like other automatic movements from Nomos, DUW 5001 has a wide rotor that extends around the movement. This trades width for depth, resulting in a thin 4.3 mm movement that is just as wide at 31 mm as the date version, DUW 5101.
