El Primero Chronomaster Grande Date

An alliance of useful complications, the chronograph measures 1/10ths of a second and shows the moon and sun phases. The indication reflecting the double path of the sun and the moon is displayed by means of two superimposed discs. The transparent upper disc with two moons performs one rotation every 59 days, while the lower day/night disc makes one turn every 24 hours. Through a dial opening at 11 o’clock, El Primero Calibre 4047 reveals the visually stunning vision of its beating heart.
