Chronomaster Open

The Zenith Chronomaster Open Boutique Edition reference 03.3300.3604/51.M3300 is a refined and technically expressive certified pre-owned luxury watch, offered in very good condition with original box and papers. Produced as a Boutique Edition, this model showcases Zenith’s signature open-dial aesthetic paired with the brand’s legendary high-frequency chronograph expertise.

Housed in a 39.5 mm stainless steel case, the watch offers elegant proportions and excellent wearability, striking a perfect balance between classic chronograph design and contemporary refinement. The polished and brushed finishes enhance the case’s crisp lines, while the overall profile remains versatile for both formal and everyday wear.

The standout blue dial features Zenith’s distinctive open aperture at 10 o’clock, revealing the beating heart of the movement and offering a dynamic visual connection to the mechanics. Applied hour markers, faceted hands, and contrasting chronograph sub-dials ensure clarity and depth, while a date display at 6 o’clock adds everyday practicality without disrupting the dial’s symmetry.

Powering the watch is the iconic Zenith El Primero Calibre 3604, an automatic chronograph movement operating at 36,000 vibrations per hour (5 Hz). This high-frequency calibre enables precise measurement of elapsed time to 1/10th of a second and delivers a power reserve of approximately 60 hours, underscoring Zenith’s long-standing leadership in chronograph innovation. The movement can be admired through the sapphire crystal case back.

The watch is fitted with a stainless steel bracelet, providing comfort, durability, and a cohesive aesthetic with the case. A scratch-resistant sapphire crystal protects the dial, ensuring lasting clarity and resilience.

The Zenith Chronomaster Open Boutique Edition 03.3300.3604/51.M3300 stands out for its open-worked design, high-frequency chronograph movement, and exclusive boutique status.
