Zenith Defy Lab - the world’s most accurate mechanical watch

Zenith Defy Lab watches is both an evolution and an improvement on the balance and hairspring regulator invented in January 1675 by the scientist Christiaan Huygens. This advance constitutes an outright challenge to the fundamental operating principle of mechanical watches https://www.aomwatches.is/.


To achieve this performance, the Zenith Defy Lab watches is equipped with a single element oscillator that measures just 0.5 mm in thickness, replacing the traditional balance-and-spring assembly. The Defy Lab beats at a frequency of 15 Hz with an amplitude of +/- 6 degrees – three times the frequency of the iconic Zenith El Primero movement. This gives it exceptional accuracy, with a daily rate precise to just 0.3 seconds, and a 60-hour power reserve.

Insensitive to temperature gradients, gravity and magnetic fields, the Defy Lab maintains the same degree of precision for 95% of its power reserve. This is also the first watch with a case made from Aeronith, an aluminum composite lighter than titanium, aluminum or carbon fiber.
