The Chronomaster Sport 160th Anniversary Edition may be the most beautiful watch ever to house the esteemed movement. The dial, coated in a blue lacquer that matches the ceramic case, contains the three tonal overlapping subdials indicative of the Chronometer.

A 60-second counter at three o’clock is a darker, contrasting blue to the dial, while the running seconds dial at nine o’clock and the 60-minute counter at six o’clock are separate shades of silver.

The hands and hour markers are plated in rhodium, an element that resembles platinum but is harder and more corrosion-resistant, and inlaid with SuperLuminova.

Because the central chronograph hand rotates fully every ten seconds, the blue ceramic bezel is marked with a 10-second track in white, with dashes indicating each tenth of a second.

An exhibition case back displays the oscillating weight with Zenith’s 160th-anniversary logo cut out in relief.
