NOMOS Caliber DUW 5001

The NOMOS Glashutte caliber DUW 5001 is an in-house automatic movement with 26 jewels, made in Germany. The DUW 5001 is based on the NOMOS Epsilon which was the first automatic movement to be produced in-house by NOMOS starting in 2005. The DUW 5001 was introduced in 2018 as evolution in the brand’s line of automatics.

From NOMOS:

“A reliable pacesetter for the larger automatic watches from NOMOS Glashütte, highly praised for its outstanding winding rate: DUW 5001 stands for excellent accuracy, a great deal of craftsmanship, Glashütte heritage—and a dash of independence. Since the pace is set by the renowned NOMOS swing system.” –source

Chronometer?

Although not COSC certified, NOMOS claims that each watch with the caliber DUW 5001 movement is adjusted according to chronometer standards. The word chronometer is not used on the movement or the dial, but the brand seems to want accuracy to be expected with their products, therefore not necessary to imply on the watch itself.

Swing System:

The DUW 5001 is equipped with the proprietary NOMOS Swing System escapement. This is the brand’s own in-house design/invention. When mentioning their Swing System in marketing materials, NOMOS uses the word “independence” frequently. This part appears to be the brand’s freedom from escape(ment) from dependency on parts from the Swiss conglomerates.
