This 39.5mm chronograph presents Zenith's El Primero 3604 movement through an open caseback, revealing the exposed escapement and silicon components designed to operate without additional lubrication. The 18K rose gold case houses a matte silver dial with three counters positioned at 3, 6 and 9 o'clock, alongside a transparent running seconds display. The chronograph mechanism measures elapsed time to 1/10th of a second precision, whilst the automatic movement delivers a 60-hour power reserve.
The watch sits on a blue calfskin leather strap and water resistant to 100 metres. The open architecture of the movement bridges Zenith's heritage with contemporary watchmaking, showcasing the high-frequency beating heart that defines the Chronomaster collection's design philosophy established over five decades.
