Zenith ChronoMaster Tourbillon Moonphase Day & Night

ZENITH presents a Grande Complication novelty, a unique combination of a Tourbillon, a Date Chronograph, and a day/night and moon phase indicator.

A true technological revolution, the new El Primero 4034 movement comprises 353 parts and 35 rubies, and has a power reserve of over 50 hours. Technical prowess aside, the look of the watch harks back to the conventions of traditional watchmaking craftsmanship. The grain d’orge guilloché pattern on the dial, the wavy guilloché pattern on the counters and on the moon disk convey a touch of hand-crafted sophistication that is particularly elegant.

Made entirely of solid gold, with a 45 mm case, dial, appliqués and hands, the Zenith ChronoMaster Tourbillon El Primero Moonphase is made for those who love beautiful objects and especially for Haute Horlogerie connoisseurs.
