Description

This date caliber effectively showcases the NOMOS swing system, our proprietary escapement. This innovative component with a blue balance spring is surrounded by fine sunbeam ribbing. It not only enhances the three-quarter plate, which is a traditional feature of Glashütte watchmaking, but also incorporates the plate of the date ring around the movement. To make the NOMOS swing system even easier to observe, the balance cock has been elegantly skeletonized.

And that's just the exterior of this fine movement. The picture does not show the mainspring barrel, which can store power for 52 hours. The quick-set date is also particularly convenient. You can easily jump forward in time with just a few turns of the crown. To do so, the crown must be pulled into the second of three positions.
