Zenith Chronomaster 2 Limited Edition

The iconic Zenith El Primero movement is celebrating its 50th anniversary this year and the Swiss luxury watchmaker has utilized this opportunity to unveil this cult movement in its modernised version, fitted in the emblematic Chronomaster. The new El Primero lineage is inaugurated with series of 250 titanium models featuring an original ceramic bezel and skeleton dial.

Reinterpreted to ensure greater modularity, the El Primero 3600 calibre has been designed using the latest technologies, while preserving the DNA of the original movement. Also beating at the high frequency of 36,000 vibrations per hour, it measures and displays tenths of a second. Alongside the original El Primero, it will gradually be introduced on other models in the range and equipped with various functions.

At Zenith, celebrating the mythical El Primero – a high-frequency star born in 1969 – is about showing respect for the past, taking root in the present and looking resolutely towards future horizons. In this spirit, the Manufacture’s engineers have redesigned the world’s most accurate automatic chronograph movement, offering a modernised version that is faithful to the architecture and proven performance of the original.

The strict specifications stipulated modularity, optimised industrial production, assembly and adjustment, the addition of a stop-seconds device and autonomy increased to a full 60 hours. As an added bonus, it was to provide the option of integrating several functions and displays as well as ensuring enhanced user friendliness – all the while complying with the absolute necessity of preserving the integrity and identity of the original El Primero.

Renamed El Primero 3600, this optimised caliber is thus endowed with the main attributes of its predecessor: a 1/10th of a second chronograph function, along with integrated construction incorporating a lateral clutch, column wheel and ballbearing-mounted central rotor. The difference lies in the fact that it has been developed using the latest technologies and performance algorithms.

The most obvious modifications are as follows: a tenth-of-a-second display on a scale with 100 graduations; the addition of a balance-stop device; a reversal of the crown sequence; adjustment of the wheels and gears; enlarged and centred design of the column wheel; and most visibly of all, an optimised lateral clutch that now includes two intermediate wheels.

To inaugurate the new-gen El Primero, Zenith has chosen an emblematic contemporary collection: the Chronomaster. Its imposing stature and distinctive design are in line with the DNA of the Maison. Equipped with the El Primero 3600 movement, the Chronomaster 2 also flaunts a modernised look with a light titanium case, black or blue ceramic graduated bezel, skeleton dial with solid counters and star-shaped oscillating weight.

Graced with three distinctive colours – light grey, blue and anthracite – the display is distinguished by a direct tenth-of-a-second read-off. The red chronograph hand makes a full sweep of the dial in ten seconds, indicating with each jump successive tenths of a second on the 100 graduations of the flange and bezel.

In addition to measuring and displaying tenths of a second, this Chronomaster, operating at 36,000 vibrations per hour, features hour and minute functions in the centre, 60-minute and 60-second chronograph counters, running small seconds and date, while delivering a minimum 60-hour power reserve.

Available in two limited series of 250 pieces each the Chronomaster 2 is fitted with a blue or black ceramic bezel.
