The Zenith Chronomaster Original Triple Calendar

The ZENITH Chronomaster Original Triple Calendar signifies an illustrious return, marrying historical elegance with modern innovation. This iconic timepiece, a distinguished variant of the El Primero that has captivated enthusiasts for over half a century, is celebrated for its legibility. The latest iteration masterfully combines the high-performance El Primero automatic high-frequency chronograph with a triple calendar and moon phase functionality, all within a sleek design that echoes the esteemed Chronomaster lineage.

This remarkable timepiece traces its origins back 55 years, to the inaugural El Primero launched in 1969, which was originally conceived to incorporate triple calendar and moon phase features. Despite the creation of 25 prototypes in 1970, the comprehensive introduction of the triple calendar variant was postponed due to the overwhelming success of the basic chronograph model.

Distinguished within the Chronomaster collection for its unparalleled versatility and utility, the Chronomaster Original Triple Calendar boasts a precision 1/10th of a second chronograph, a legible full calendar, symmetrically arranged windows for days and months, a date indicator at 4:30, and an enchanting moonphase display at 6 o’clock.

Encased in a 38mm steel frame inspired by the 1969 A386 model, it retains the classic proportions while integrating sophisticated functionalities. It presents two dial options: a “panda” silver opaline dial with contrasting black counters, and a slate-grey dial with silvery-white counters, both adorned with rose gold-tone markers and hands, and a moon accentuated against a blue sunray-patterned disk. An exclusive boutique edition features a sunburst olive-green dial.

Powered by the El Primero 3610 calibre, operating at 5 Hz, it delivers a 1/10th of a second chronograph feature and a robust 60-hour power reserve, even with the added calendar mechanisms. The sapphire display back elegantly reveals the intricate movement.

Offered with either a steel bracelet or a calfskin strap, the strap colors are thoughtfully coordinated with the various dial options, ensuring a harmonious aesthetic.
