About this watch
The Zenith Chronomaster Open, reference 03.3300.3604/69.M3300, is a contemporary expression of Zenith’s legendary high-frequency chronograph expertise. Instantly recognisable for its open-heart display revealing the regulating organ, this certified pre-owned luxury watch is presented in new condition and supplied as a full set with its original box and papers.
The watch features a 39.5 mm stainless steel case with refined proportions and a balanced wrist presence. The silver dial enhances its elegant yet technical character, complemented by Zenith’s signature overlapping chronograph sub-dials. The open aperture at approximately 9 o’clock reveals the high-frequency escapement in motion, offering a direct view of the 5 Hz (36,000 vibrations per hour) balance wheel. Applied hour markers and faceted hands filled with luminous material ensure excellent legibility.
Powering the watch is the in-house Zenith El Primero 3604 automatic chronograph movement. This advanced calibre operates at a high frequency of 5 Hz, allowing precise 1/10th of a second chronograph measurement. It features a column wheel architecture and delivers a power reserve of approximately 60 hours. The movement can be admired through the sapphire crystal case back, showcasing Zenith’s careful finishing and technical mastery.
The stainless steel bracelet integrates smoothly with the case, providing durability, comfort, and a cohesive sporty-elegant aesthetic. Offered in new condition and accompanied by its original box and papers, this pre-owned luxury watch represents an exceptional opportunity to acquire a full set Zenith Chronomaster Open 03.3300.3604/69.M3300, combining iconic El Primero performance, contemporary design, and refined mechanical transparency.
