Zenith Chronomaster El Primero Open Tour Auto Edition

Zenith has created a special edition Chronomaster El Primero Open Tour Auto timepiece to celebrate its association with the 2017 Tour Auto Optic 2ooo motor sports event that held from April 24th to 30th.

This exclusive watch features elegant bodywork, powerful engine and tricolour accents. The Chronomaster El Primero Open Tour Auto Edition houses the legendary El Primero 4061 automatic chronograph calibre that beats at 36,000 vibrations per hour. The famous 11 o’clock dial opening reveals the beating heart of this 282-part COSC chronometer-certified movement – reliably driving central hours and minutes hands, chronograph and tachymeter functions, as well as a tenth-of-a-second display, while ensuring a 50-hour power reserve.
The  Chronomaster El Primero Open Tour Auto Edition  has a 42 mm-diameter brushed steel case, topped by a slender polished bezel framing the slate grey dial decked out in vertical blue-white-red vertical stripes – a reference to the tricolour French rally banner picked up in several design details. The distinctive dial ensures optimal legibility in any lighting, while the exhibition case-back bearing the engraved race logo reveals an oscillating weight adorned with a “Côtes de Genève” motif.
