Unworn, Zenith Chronomaster Sport, Ref#51.3100.3600/69.M3100, box & papers

The Zenith Chronomaster Sport 51.3100.3600/69.M3100 harmoniously blends timeless chronograph heritage with contemporary performance and design. This refined yet sporty wristwatch features a striking silver dial with contrasting sub-dials and a fixed rose gold bezel with a 1/10th-of-a-second scale, capturing the spirit of Zenith’s legendary high-frequency chronographs. At its heart beats the El Primero 3600 automatic calibre, one of the most advanced chronograph movements from the Swiss manufacture, offering a central chronograph hand that makes a full revolution every 10 seconds for precise 1/10th-second time reading, and a robust 60-hour power reserve. The elegant 41 mm case crafted in stainless steel and 18 k rose gold sits comfortably on the wrist, combining polished and brushed surfaces for dynamic visual appeal. With 100 m water resistance and a seamlessly integrated steel and rose gold bracelet, this watch is equally suited for everyday sportiness and refined occasions. The watch is unworn in like-new condition, comes with box and papers, and includes warranty documents dated.
