When you think of chronographs, you think of Zenith. In 1969, the marque was the first watchmaker to introduce an automatic high-frequency integrated chronograph with its landmark 'El Primero' movement, and to this day, it sits at the forefront of technological advancement in the horological industry.

At this week's Watches & Wonders fair in Geneva, Zenith has reaffirmed its heritage with an exhibition titled “Master of Chronographs” which illustrates the marque's various milestones since the late Sixties. The exhibition serves as the launchpad for Zenith's latest chronograph, the Chronomaster Open.

On first view, it is as handsome and well-proportioned as any Zenith chrono. But when you get it on wrist, as we were lucky enough to do, its compactness is quite startling. At just 39.5mm diameter, the case houses a tri-colour trio of sub-dials (reminiscent of the original El Primero colourways), as well as windows through to the movement within, allowing the watch's 'beating heart' take pride of place. The silicon escape-wheel and lever, oscillating gently within, provide a 60-hour power reserve.

The Chronomaster Open is available in stainless-steel with a black or silver matter dials, and in 18ct rose gold.
