DUW 4101 Calibre "Swing System"
This watch features the Nomos Swing System - a spring and escapement designed and built by Nomos.
The distinctive blue balance spring can be used to identify Nomos watches using the Swing System which is manufactured by Carl Haas.
The Nomos Tangente remains a signature watch for the brand. This version of the Tangente adds two new features to the original Tangente, while retaining the manually wound movement:
- Case size increased from 35 mm to 38.0 mm
- Large date display at 6
Silver plated dial with a combination of Arabic and hour markings.
The dial contains an off-center subsidiary seconds dial. The dial is first sand blasted, then bathed in silver to provide the unique Nomos coloring. The baton hands are made of polished steel and are blued.
The case is made in a special steel alloy which is nickel-free. Sapphire crystal on front and back.
And last but not least - the strap. Nomos watches use hand stitched straps made from Shell Cordovan. The leather is very smooth, durable, water-resistant and extremely long-lived.
Large Date Display
This watch features a new patented Nomos large date display. This date display is not only easier to read because of its larger size, it's also printed in the typography used on the overall dial design.
To make room for all of the additional parts required for this new large date display, the overall case size of the watch has been increased from earlier models.
