Abstract

A display ring is driven via a satellite pinion for displacement relative to a viewing window in the watch face and a fixed reference ring. The display ring has a sky-coloured background surface with at least one circle representing the moon, the reference ring having a slot through which the latter is visible with convex edges at each side allowing a crescent shaped representation of the moon to be provided. Pref. the lunar phase representation is combined with a date display. ADVANTAGE - Indicates corresp. lunar phase for each successive date.
