EL PRIMERO CHRONOMASTER OPEN GRANDE DATE MOON & SUNPHASE

In 2012, Zenith is enriching the El Primero collection by unveiling the El Primero Chronomaster Open Grande Date Moon & Sunphase model in two new rose gold and steel versions. In addition to the chronograph which, like all El Primero movements, measures 1/10ths of a second, Calibre 4047 also indicates the hours, minutes, small seconds at 9 o’clock, large date at 2 o’clock – by means of two concentric discs – as well as displaying the moon and sunphases at 6 o’clock. The latter is a useful and poetic complication specific to Zenith, portrayed by an indication reflecting the double path of the sun and moon by means of two superimposed discs. The transparent upper disc with two polished metallic moons performs one rotation every 59 days, while the lower day/night disc makes one full turn every 24 hours. The El Primero Calibre 4047 comprises 332 parts serving to display this range of useful complications.
