Limited Edition of 10 Pieces in Platinum and 50 in Black Carbon
Two years ago, Zenith introduced the revolutionary Defy El Primero 21, the only high-frequency automatic chronograph designed to measure hundredths of a second, ushering watchmaking firmly into the 21st century. In 2019, the Swiss Manufacture is taking another big leap with the Defy El Primero Double Tourbillon: an innovative model powered by the El Primero 9020 calibre and its two separate escapements. One of the latter serves to keep the chronograph beating at an exceptional frequency and power the 1/100th of a second display, while the other ensures the lasting precision of the watch. This model is available in two limited editions: a 10-piece platinum version and a 50-unit carbon interpretation.
One sweep of the dial per second
With its DefyY collection, Zenith is constantly innovating and setting the standard for tomorrow's watchmaking: after the unequalled Defy El Primero 21, the first serially produced mechanical chronograph to provide hundredth of a second measurement; followed by the Defy Lab, the world's most accurate mechanical watch with an unprecedented oscillator, the Haute Horlogerie manufacturer is unveiling the Defy El Primero Double Tourbillon. This unprecedented combination of horological complications two tourbillons and a 1/100th of a second chronograph features truly exceptional qualities.
For this model, Zenith has developed two tourbillons, a first for the Maison. In an additional feat, one of the tourbillons (at 10 o'clock) is coupled with and regulates the chronograph measuring and displaying hundredths of a second in a perfectly legible manner. Beating a frequency of 50 Hz (360,000 vibrations per hour) with its carriage performing a complete rotation every five seconds, this tourbillon is the fastest in the world. It drives the chronograph hand at the amazing speed of one full turn of the dial per second. The second tourbillon (at 8 o'clock), operating at 5 Hz with a carriage performing one rotation per minute, regulates the rate of the watch, meaning the hours, minutes and seconds.
