The Zenith Chronomaster Open is one of the most celebrated expressions of Zenith's dedication to in-house haute horlogerie, and reference 03.3300.3604/69.M3300 represents that tradition in its most accessible and wearable form. Presented here brand new, this 39.5mm stainless steel model pairs a clean silver index dial with the brand's iconic open-heart display, giving the wearer an intimate window into the oscillating balance wheel that has defined Zenith's watchmaking philosophy for generations.

Zenith's Chronomaster line traces its roots directly to the legendary El Primero caliber, widely regarded as the world's first automatic high-frequency chronograph movement when it was introduced in 1969. That heritage is not merely marketing — it represents a genuine milestone in mechanical watchmaking, and the Chronomaster Open wears that legacy proudly on its dial. The open aperture, typically positioned at the 11 o'clock area, transforms the act of reading time into a moment of mechanical appreciation.

At 39.5mm, this case size occupies a sweet spot between classical restraint and modern presence. The stainless steel construction ensures durability and long-term resilience, while the polished and brushed finishing typical of this line lends a refined, dressy quality that suits both business and casual settings. The silver index dial radiates clean legibility, with applied indices catching the light in a way that elevates the overall aesthetic beyond a purely utilitarian timepiece.

The steel bracelet supplied with this reference completes the ensemble with coherent, integrated wrist presence. Integrated or closely fitted to the lugs, it enhances the overall silhouette and ensures the watch sits comfortably and securely. The stainless steel bezel frames the dial with understated confidence, allowing the open-heart aperture and silver dial to remain the focal point without unnecessary ornamentation.

Buying a brand-new Zenith Chronomaster Open 03.3300.3604/69.M3300 from Bizak & Co. means investing in an iconic reference at its very best condition — unworn, in original form, and backed by the expertise of a knowledgeable luxury watch dealer.
