AN INVITATION TO STAR GAZING IN BLUE: THE CHRONOMASTER ORIGINAL TRIPLE CALENDAR LAPIS LAZULI
The name ZENITH was born from a star-dusted sky. Gazing at the celestial canopy, Georges Favre-Jacot, the brand’s founder, envisioned the zenith—the highest point a star can reach in the sky—as the perfect embodiment of his aspiration for watchmaking excellence. A reflection of limitless possibilities, blue has become ZENITH’s signature colour. Following the introduction at Watches and Wonders 2025 of the G.F.J. and the 160th anniversary blue ceramic trilogy, it is now time for another ZENITH classic to be dressed in blue. The CHRONOMASTER Original Triple Calendar is now graced with a captivating lapis lazuli dial—at once compelling, functional, and rich with evocation.
Horology is often regarded as a child of astronomy—born from humanity’s enduring quest to measure time through the movements of celestial bodies. Echoing these cosmic cycles, the CHRONOMASTER Original Triple Calendar displays the hours, date, day of the week, month, and moon phases in perfect harmony. In its latest iteration, the model features a dial crafted from lapis lazuli, evoking a starry night sky with its deep blue hue scattered with shimmering, gold-colored pyrite inclusions. Naturally occurring, these mineral flecks ensure that no two dials—and therefore no two watches—are ever exactly alike.
Rendered in a refined silver tone, the three counters and the 1/10th of a second chapter ring offer striking contrast and exceptional legibility. The complete calendar indications are seamlessly integrated and intuitively arranged. The day of the week and the month appear above the chronograph counters, at 11 o’clock and 2 o’clock respectively. The date is discreetly positioned at 4:30, while the moon phase is elegantly embedded within the chronograph minute counter at 6 o’clock.
A true ZENITH classic, the complete calendar chronograph was reintroduced in 2024 as the CHRONOMASTER Original Triple Calendar. Its compact 38mm round case draws inspiration from the emblematic 1969 A386, featuring pump-style pushers, tapered lugs, and a raised box-shaped sapphire crystal.
At its heart beats the automatic El Primero 3610 calibre, a modern evolution of ZENITH’s iconic high-frequency chronograph, now enhanced with a true 1/10th of a second function. The chronograph seconds hand completes a full rotation of the dial in just 10 seconds, precisely indicating 1/10th of a second on the silver-toned chapter ring. With a 60-hour power reserve and a stop-seconds mechanism for precise time-setting, this movement is a perfect blend of heritage and innovation.
The sapphire display case back reveals the intricate architecture of the movement, including a striking blue column wheel and an openworked rotor bearing the ZENITH five-pointed star.
The CHRONOMASTER Original Triple Calendar Lapis Lazuli comes fitted with a blue calfskin leather strap secured by a stainless-steel folding clasp and is also delivered with a matching steel bracelet with folding clasp—offering versatility and effortless style.
The CHRONOMASTER Original Triple Calendar Lapis Lazuli is available at ZENITH boutiques, on the brand’s official website, and through authorized retailers worldwide.
ZENITH: THE HEART OF WATCHMAKING
Founded in 1865 in Le Locle, Switzerland, ZENITH has been at the forefront of Swiss watchmaking for over 160 years, driven by a pioneering spirit and a relentless pursuit of precision. As the first vertically integrated Swiss watch manufacture, ZENITH has continuously revolutionized horology by developing and manufacturing in-house movements, most notably the El Primero, the world’s first automatic chronograph calibre launched in 1969, renowned for its unparalleled precision and high-frequency performance.
ZENITH’s timepieces celebrate its dedication to innovation and exceptional craftsmanship. The CHRONOMASTER collection highlights the brand’s mastery of high-precision chronographs, the DEFY showcases technical innovation and bold design, while the PILOT collection celebrates ZENITH’s storied aviation legacy with distinctive, adventure-ready timepieces. This unwavering commitment to precision has been recognized with an unparalleled 2,333 chronometry prizes, underscoring ZENITH’s enduring legacy of excellence. The calibre 135, having won most of those prizes went through a modern re-engineering integrating up-to-date technical solutions and materials. ZENITH decided to give it a new home in its newly introduced G.F.J collection.
Throughout its history, ZENITH timepieces have accompanied pioneers who dared to dream big and achieve the extraordinary: from Louis Blériot’s historic flight across the English Channel to Felix Baumgartner’s record-breaking stratospheric free-fall jump. This daring spirit continues to drive the Maison as it redefines the future of Swiss watchmaking.
Celebrating over a century and a half of excellence, innovation, and purpose, ZENITH remains at the forefront of Swiss horology, empowering those who challenge conventions and strive for greatness.
From Le Locle to the world, from 1865 to now, ZENITH is the heart of watchmaking.
