Zenith Chronomaster Sport 51.3100.3600/69.M3100

Zenith Chronomaster

Steel and 18k rose gold frame Zenith’s high-frequency El Primero 3600, delivering true 1/10th-second chronograph precision in a modern 41mm case. The Chronomaster Sport masterfully blends heritage and cutting-edge performance. Its silver sunray dial with signature tri-colour counters nods to Zenith’s most iconic chronographs, while the steel and rose gold construction adds warmth and contemporary presence on the wrist. At its core beats the El Primero 3600, a 5 Hz (36,000 vph) automatic chronograph capable of measuring 1/10th of a second with a central hand that completes one rotation every 10 seconds. The movement comprises 311 components and delivers a robust 60-hour power reserve, pairing technical finesse with everyday reliability. A date at 4:30, small seconds at nine, and 60-minute and 60-second counters at six and three complete the balanced, highly legible layout. With 100 metres of water resistance and a solid steel and rose gold bracelet, this is a chronograph that feels equally at home on the track, in the boardroom or at a fine dinner.
