Self-winding mechanical watch. With 2nd time zone and large date display. Black dial with rhodium markers.

  • The velvety coating of the face in black almost totally absorbs light and subtly adopts the color nuances of the environment.
  • The material cannot be mechanically machined. The appliques are elaborately riveted into holes that are drilled prior to coating. 
  • The appliques and cabochons are rhodiumed.
  • Date disksLike the appliques on the dial, the numerals are also three-dimensional.
  • The hands are crafted to our specifications. 
  • They are rhodiumed to match the appliques.
  •  Self-winding mechanical movement with Swiss lever escapement.
  • Balance frequency 4 Hz (28,800 semi-oscillations per hour).
  • The base movement is the high-end version of the proven ETA 2892A2 caliber.
  • The power reserve when fully wound is approx. 42 hours.
  • 21 bearing jewels. 
  • The Technotime complication indicates the 2nd time zone and the large-format date. 
  • Calendar with quick date change by turning the crown.
  • Stop seconds by pulling the crown.
  • Decoration: Geneva striping, rhodiumed.
  • Serial numbers of movement and case identical.

Further special feature:

After the movement is cased, the air is evacuated from the case through the stem tube and replaced with argon, a noble gas. 

Why argon: Argon is inert and prevents oxidation of the lubricants. This considerably extends their service life and thus the maintenance intervals.
