The crystal-clear sapphire dial features two transparent blue and grey tinted counters “the aesthetic signature of the original 1969 model” and shows the moon & sunphases on twin discs at 6 o’clock. A silver toned inner bezel ring surrounded by a blue ring, a black and white minute scale, along with luminescent facetted hands and hour-markers, all contribute to ensuring optimal legibility, yet without obscuring the view of the fascinating inner workings. The large date at 2 o’clock -shown by two concentric discs with cut-out numerals- is read off against a bright red background in an engraved aperture, while the slim red-tipped central sweep-seconds hand adorned with the emblematic Zenith star sweeps over the display.

Topped by a domed crystal and fitted with a sapphire crystal case-back, the 45 mm steel case -water resistant to 100 metres- reveals on both sides the outlines of the movement. Equipped with a silicon lever and escape-wheel, this movement drives central hours and minutes hands, along with small seconds, chronograph, large date, moon & sunphase functions, while maintaining an over 50-hour power reserve. The celestial kinetic ballet is shown on two superimposed discs, with the moon disc rotating every 59 days (two lunar cycles) and the day/night disc making one full turn in 24 hours.
