Zenith Chronomaster Open Heart Automatic 39.5 mm 03.3300.3604/69.M3300
The Zenith Chronomaster Open Heart (Ref. 03.3300.3604/69.M3300), a spectacular 2022 evolution that beautifully showcases Zenith's high-frequency mechanical theater within a perfectly proportioned case. This striking 39.5mm stainless steel masterpiece retains the brand's iconic overlapping tricolor sub-dials, creatively utilizing a completely transparent sapphire disc for the running seconds at 9 o'clock so it doesn't interrupt the view into the heart of the engine. Through the signature dial cutaway OR OPEN HEART, you are treated to a captivating visual display of the balance wheel swinging alongside a high-tech purple and blue silicon escape wheel—precision-cut into the shape of the iconic Zenith Star.
Under the hood lies the exceptional, next-generation El Primero Caliber 3604 automatic movement, ticking at a lightning-fast 36,000 vibrations per hour (5Hz) to provide a true 1/10th of a second chronograph function. When activated, the central chronograph hand blazes around the dial once every 10 seconds, delivering an exhilarating mechanical performance backed by a robust 60-hour power reserve. Riding on a beautifully integrated, sport-elegant three-link stainless steel bracelet, this contemporary heavy-hitter delivers an upscale, micro-engineered wrist presence that remains completely clean.
Presented in polished condition, this investment-grade timekeeper is offered as a complete full set, arriving meticulously preserved with its inner and outer boxes, booklets, and original Zenith warranty card.
