Zenith Chronomaster El Primero Grande Date
The new Zenith Chronomaster El Primero Grande Date Full Open is all about transparency.
Locked into a 45 mm case, the skeleton-worked mechanism of the Chronomaster El Primero Grande Date Full Open displays its column wheel and silicon escapement under a dial carved in sapphire. This latter features two transparent blue- and grey-tinted counters – the aesthetic signature of the original 1969 model. A silver-toned inner bezel ring surrounded by a blue ring, a black and white minute scale, along with luminescent facetted hands and hour-markers, all contribute to ensuring optimal legibility, yet without obscuring the view of the fascinating inner workings. The large date at 2 o’clock – shown by two concentric discs with cut-out numerals – is read off against a bright red background in an engraved aperture, while the slim red-tipped central sweep-seconds hand adorned with the emblematic Zenith star sweeps over this perfectly clear display.
Equipped with a silicon lever and escape-wheel, this 332-part movement drives central hours and minutes hands, along with small seconds, chronograph, large date, moon & sunphase functions, while maintaining an over 50-hour power reserve. The celestial kinetic ballet is shown on two superimposed discs, with the moon disc rotating every 59 days (two lunar cycles) and the day/night disc making one full turn in 24 hours.
The impressive stature of the Chronomaster El Primero Grande Date Full Open, complete with its fluted crown and double round pushers, is further enhanced by a steel bracelet or a black leather rubber-lined strap. Another version is available with a two-tone exterior (stainless steel case with a pink gold bezel), teamed with a chestnut leather strap.
Ever since it was founded, Zenith has been cultivating the ability to open up new horizons by assisting with some of the most remarkable human achievements.Find out more
