Two years ago, Zenith introduced the revolutionary Defy El Primero 21, the high-frequency automatic chronograph designed to measure hundredths of a second. Now, the Swiss Manufacture is taking another big leap with the Defy El Primero Double Tourbillon.
With its Defy collection, Zenith is constantly innovating. After the 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 manufacturer is unveiling the Defy El Primero Double Tourbillon. This combination of horological complications – two tourbillons and a 1/100th of a second chronograph – features exceptional qualities.
For this model, Zenith has developed two tourbillons, a first for the Maison. In an additional feat, one of the tourbillons (the one at 10 o’clock) is coupled with and regulates the chronograph measuring and displaying hundredths of a second. Beating at a frequency of 50 Hz 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 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 – hours, minutes and seconds.
Echoing this dial architecture, two dedicated barrels – one for the wacth and the other for the chronograph – store and deliver energy. They respectively provide 60 hours of power reserve for the watch and 50 minutes for the 1/100th of a second chronograph. Hier to the legendary 1969 El Primero, this new high-frequency in-house movement drives the hours, minutes, 1/100th of a second chronograph, 60-second and 30-minute counters (at 6 and 9 o’clock respectively), along with a chronograph power-reserve indicator at 12 o’clock.
The Defy El Primero Double Tourbillon also stands out for its powerful aesthetics. With its generously openworked dial accentuated by a two-tone treatment – a new signature of Zenith Haute Horlogerie movements – El Primero 9020 and its 311 components are shown to full advantage. The blue-treated tourbillon carriages with the Zenith star, along with the bridges and baseplate, feature polished angles that further enhance the 3D view of the stunning mechanism in motion.
Whether crafted in platinum with the collection’s characteristic satin-brushed and polished finishes and a sapphire case back, or entirely made of carbon, the case is water-resistant to 100 metres. It is completed by a black rubber strap, coated with alligator leather or Cordura-patterned.
This model is available in two limited editions: a 10-piece platinum version and a 50-unit carbon interpretation.
