Nomos Beta

Nomos Beta (β) is a manual winding movement with date display.

Based on the manual winding Nomos Alpha movement, the Beta adds an unusual and patented date display. Typically, a date wheel and associated gears are stacked below the mainplate between the rest of the watch movement and the dial. However, this makes these movements more bulky and thick. Instead, Nomos places the date ring around the movement, with the switching mechanism integrated into the movement itself, making the Beta and Delta just as thin as the Alpha, on which they are based.

Like all Nomos movements, the Beta is decorated in the Glashütte style, including a three-quarter plate, hacking seconds, Glashütte Stripes, solar grinding or Langeleist-Perlage.

For the Tangente Observatory, the date index is modified to functions as a day/night display.
