May 2, 2012: Since the advent of the first automatic integrated chronograph, Zenith’s famous collection of El Primero calibres has constantly evolved. In 2012, Zenith has further enriched this major collection by unveiling the El Primero Chronomaster Open Grande Date Moon & Sunphase with exceptional chronographic performances.
The dial opens onto the beating heart of the movement that reveals the regulating organ and its high-frequency vibrations. The watch displays celestial movements at 6 o’clock and the days passing through the large date aperture at 2 o’clock. Zenith has created a dial with a sunburst motif radiating from the centre, along with circular satin-brushed chapter-ring zone and counter zone at 3 o’clock, while the sun and moon aperture at 6 o’clock is sunburst guillocheÌ-worked on its lower section. 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
Water-resistant to 50 metres, the watch is fitted with a black alligator leather strap with matching metal buckle. 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 complication.
