The Zenith Chronomaster Open, reference 03.3300.3604/21.M3300, is a contemporary expression of the brand’s legendary high-frequency chronograph expertise. Instantly recognisable for its open dial revealing the beating heart of the movement, 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 black dial delivers a bold and modern aesthetic, enhanced by contrasting chronograph sub-dials and the signature open aperture at 9 o’clock, offering a direct view of the high-frequency escapement. Applied hour markers and luminous hands ensure optimal legibility, while the classic chronograph layout preserves harmony and functionality.
Powering the watch is the Zenith El Primero Calibre 3604 automatic chronograph movement. Operating at 36,000 vibrations per hour (5 Hz), this in-house high-beat calibre enables precise 1/10th of a second chronograph measurement and offers a power reserve of approximately 60 hours. The movement can be admired through the sapphire crystal case back, showcasing Zenith’s modern finishing and technical mastery.
The stainless steel bracelet integrates seamlessly 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 03.3300.3604/21.M3300, combining iconic open-heart design, high-frequency chronograph precision, and contemporary Swiss craftsmanship.
