• DUW 4001 Duo: DUW 4001 Duo is based on the DUW 4001 architecture but is configured specifically for two-hand displays. Compared to the standard version, the movement features a modified seconds wheel with a shortened arbor, allowing operation without a running seconds indication. The calibre does not incorporate a hacking seconds mechanism.

DUW 4001 contains many typical features of Glashütte calibers, from the three-quarter plate to the Glashütte stopwork and temperature blued screws. It also includes NOMOS-specific features, such as the DUW regulation system and our proprietary escapement, NOMOS swing system. This hand-wound caliber offers a stop-seconds mechanism, 53-hour power reserve, and is regulated in six positions.
