Zenith El Primero Chronomaster Sport Boutique Edition B&P 03.3103.3600/69.M3100

Offered is a Zenith Chronomaster Sport Boutique Edition reference 03.3103.3600/69.M3100 in very good pre-owned condition, with box and papers. The Chronomaster Sport Boutique Edition is an elevated take on the award-winning high-frequency chronograph, featuring design elements exclusive to this special series. The most distinctive feature is the tri-color ceramic bezel, which for the first time replicates the legendary El Primero colors—grey, anthracite, and blue—directly on the ceramic insert, allowing for an intuitive readout of the 1/10th of a second chronograph. The watch features a 41 mm stainless steel case with a mix of brushed and polished finishes. The silver sunray-patterned dial is another boutique-exclusive touch, providing a luminous backdrop for the signature overlapping tri-color sub-dials. The dial remains remarkably balanced despite its high technical capability, featuring a date window at the 4:30 position and applied faceted hour markers. At the heart of this timepiece is the El Primero 3600 automatic movement, the modern evolution of the world's most famous chronograph caliber. Operating at a high frequency of 36,000 VpH (5Hz), it allows the central chronograph hand to complete a full rotation every 10 seconds, providing a true mechanical 1/10th of a second measurement. This movement offers an increased 60-hour power reserve and is visible through the sapphire crystal caseback. Paired with an integrated stainless steel bracelet, this reference is a perfect fusion of Zenith’s 1969 heritage and contemporary watchmaking precision.
