Chronomaster Original

The Zenith Chronomaster Original Triple Calendar Lapis Lazuli, reference 03.3400.3610/51.C910, is an exceptional expression of Zenith’s heritage, pairing the legendary El Primero chronograph with a complete calendar and a striking natural stone dial. This certified pre-owned luxury watch is presented in new, never worn condition and is offered as a full set with original box and papers.

Housed in a historically faithful 38 mm stainless steel case, the watch preserves the classic proportions of the original 1969 A386, delivering a perfectly balanced and elegant wrist presence. The highlight of this reference is the lapis lazuli dial, each piece unique due to the natural stone’s deep blue tone and subtle golden inclusions. Applied hour markers and faceted hands ensure excellent legibility, while the complete calendar layout displays the day, date, month, and moonphase, harmoniously integrated with the chronograph counters.

Powering the watch is the Zenith El Primero Calibre 3610, an automatic high-frequency chronograph movement beating at 5 Hz (36,000 vibrations per hour). This calibre enables a central chronograph hand that measures 1/10th of a second with exceptional precision. It also offers a robust approximately 60-hour power reserve, combining technical performance with everyday practicality. The movement can be admired through the sapphire crystal case back, showcasing refined finishing consistent with Zenith’s manufacture standards.

The watch is fitted with a blue leather strap, perfectly complementing the lapis lazuli dial and reinforcing the model’s refined yet distinctive character. Sapphire crystal protects the dial, ensuring long-term clarity and scratch resistance.

This pre-owned Zenith Chronomaster Original Triple Calendar Lapis Lazuli, reference 03.3400.3610/51.C910, represents a rare opportunity to acquire a highly distinctive and unworn pre-owned luxury watch, combining natural stone artistry, one of the most celebrated chronograph movements in history, and timeless Zenith design.
