The Chronomaster Original Triple Calendar Lapis Lazuli is a poetic fusion of astronomical inspiration and horological precision. Taking cues from the night sky, the dial is crafted from natural lapis lazuli—its deep ultramarine hue interspersed with golden pyrite inclusions. These mineral formations are never identical, ensuring that no two watches are exactly the same. The result is a dial that feels alive, echoing the cosmic origins of Zenith’s name.

Housed in a polished stainless steel case measuring 38mm across and just 14mm thick, the watch pays homage to the 1969 A386—a cornerstone in Zenith’s history—with its pump-style pushers, box-shaped sapphire crystal, and refined proportions. Despite its vintage roots, the Chronomaster Original Triple Calendar Lapis Lazuli offers a complete contemporary calendar display: day and month at 11 and 2 o’clock, date discreetly at 4:30, and a moonphase indication set within the 60-minute counter at 6 o’clock.

Inside beats the El Primero 3610, a high-frequency automatic chronograph calibre operating at 36,000 vibrations per hour (5 Hz). This latest evolution of the iconic El Primero family allows for a true 1/10th of a second chronograph function, with the central chronograph hand making a full rotation in just 10 seconds. A stop-seconds mechanism and 60-hour power reserve round out its technical capabilities. Through the sapphire case back, collectors can admire the column wheel—rendered in blue—and the openworked rotor adorned with Zenith’s five-pointed star.

Zenith delivers reference 03.3400.3610/51.C910 with not one, but two distinct ways to wear it. The watch comes fitted with a supple blue calfskin leather strap, secured with a stainless steel folding clasp. For added versatility and a sportier aesthetic, a matching stainless steel bracelet with its own folding clasp is also included. Whether paired with tailored attire or worn more casually, the Chronomaster Original Triple Calendar Lapis Lazuli offers a refined and adaptable presence on the wrist.

An ode to Zenith’s roots in astronomy and its ongoing pursuit of mechanical excellence, this model captures the magic of time, measured in celestial rhythm and crafted in Swiss steel.
