Zenith Unveils The Chronomaster Original Triple Calendar In 18K Rose Gold
Zenith expands its Chronomaster Original collection with an elegant new edition that brings together historical design codes and modern mechanical mastery. The Chronomaster Original Triple Calendar Gold is crafted in 18k rose gold and powered by the high-frequency El Primero movement, now equipped with a full calendar and moonphase display—delivering a sophisticated take on one of the most iconic chronographs ever produced.
A Case Rooted in History
The 38 mm case is based on the original A386 model from 1969, one of the first to house the legendary El Primero calibre. In this version, Zenith maintains the original proportions with a compact 46 mm lug-to-lug span and a thickness of 14 mm, offering a balanced presence on the wrist. The rose gold case is finished with alternating polished chamfers and finely brushed surfaces, including a rare radial brushing effect that extends outward from the dial—adding dynamic texture and highlighting the watch’s attention to finishing.
Complications in Harmony
The triple calendar layout includes a date window at 4:30, day and month apertures at 10 and 2 o’clock, and a beautifully rendered moonphase display at 6 o’clock. The moonphase disc features a black sky with rose gold moon and stars, echoing the warm tones of the case and markers. The chronograph function maintains the classic El Primero layout with a central 1/10th-second chronograph hand, a 60-minute totalizer at 6 o’clock, and a 60-second register at 3 o’clock, while the running seconds is located at 9 o’clock.
A Refined Dial for a Refined Movement
The dial is crafted in a sleek black, adding depth without overwhelming the information-rich display. Rose gold accents—applied hour markers, sub-dial rings, and chronograph scale—enhance legibility while contributing to the refined aesthetic. Despite the multiple complications, the dial remains balanced and symmetrical, aided by careful placement of displays and minimal branding.
The Beating Heart: El Primero Calibre 3610
Visible through the sapphire caseback is the El Primero 3610, a modern interpretation of the original automatic chronograph movement introduced over five decades ago. Beating at 36,000 vibrations per hour (5 Hz), it delivers timing precision down to 1/10th of a second and a power reserve of approximately 60 hours. The movement is partially skeletonized, allowing an open view of the column wheel, levers, and the custom-finished rotor bearing the Zenith star.
Subtle Controls, Seamless Operation
Adjusting the calendar functions is achieved via recessed pushers along the caseband. The moonphase and weekday are controlled independently, while the quick-set date and month are accessible via the crown—a nod to the El Primero’s original modular design intended for complication integration.

Final Thoughts and Price
With the Chronomaster Original Triple Calendar Gold, Zenith bridges its 20th-century heritage with modern elegance, offering collectors a watch that is not only visually refined but also mechanically advanced. It’s a compelling choice for those seeking a gold chronograph that doesn’t compromise on utility or history. Available now at Zenith boutiques and authorized dealers worldwide for CHF 25,400.
