The luxury watch market of today is competitive, to say the least. So when a brand announces that it’s developed the most accurate mechanical watch ever, everyone pays attention.

Zenith‘s new timepiece Defy Lab has been able to achieve such a designation thanks to a proprietary silicon oscillator. The development of the triple-certified watch represents a groundbreaking moment in time measurement; it’s certainly an achievement Zenith is proud of, calling their new wristwear (in paraphrase) the next phase in the evolution of mechanical timekeeping, and the first true innovation in nearly 350 years.

Zenith’s new creation offers a fresh take on the balance and hairspring regulator introduced in 1675 by Christiaan Huygens. Oscillating at a frequency five-times greater than the standard, the incredible watch beats at an extremely high frequency: 15 Hz. Daily accuracy is an astonishing three-tenths of a second.

In addition to its groundbreaking complication, the watch features a beautiful look with a super-light Aeronith case. Aeronith is a blend of aluminum and polymer, lighter than titanium. It looks as unique as its mechanical design.

Offering superior accuracy plus a 60-hour power reserve, the Defy Lab timepiece is available for $31,000. While all ten introductory models have been sold, Zenith is expected to introduce a full production run in 2018.
