The DUW 3001 is Nomos's first fully in-house movement, including its proprietary Swing System escapement replacing the licensed Glashütte lever. At 3.2 mm height it is among the thinnest automatic calibers in German watchmaking. The Swing System reduces friction compared to a standard lever and is the technical anchor of Nomos's independence claim.

Known service issues

  • Swing System requires Nomos-trained technicians for correct pallet adjustment; do not service with standard lever escapement tools
  • The first Neomatik examples from 2015 to 2016 had a higher than expected call-back rate for regulator adjustment; current production is reliable and the issue has not recurred
