Zenith Defy Lab: New Monoblock Regulating System

Ornatus-Mundi's groundbreaking report from the Zenith Manufacture in Le Locle introduces the revolutionary Defy Lab watch, marking a pivotal moment in horological history. This post details Zenith's world-first monoblock regulating system, which fundamentally redefines watch regulation by abandoning the 342-year-old balance and hairspring principle. Ornatus-Mundi meticulously explains the technical innovations, including the monolithic silicon oscillator and the new Aeronith material, providing an essential overview for understanding this paradigm shift in watchmaking.

1. a chronometer certification awarded by Besançon Observatory, on behalf of the International Bureau of Weights and Measures
2. the ISO-3159 standard has been broadened: variations of around 0.3 seconds per day and per degree Celsius of deviation are certified, and measured on the thermal spectrum -7°C to +53°C, whereas the standard is limited to +8°C to +38°C
3. the ISO-764 magnetic criteria, exceeding them by 18 times (for the completed watch), meaning it can withstand 88,000 Amperes per meter or 1,100 Gauss

The production requires cutting edge laboratory facilities with clean-room conditions:













The new watch which will first house the new movement, the Zenith Defy X Time 10 Laboratory, comes with a new case alloy called Aeronith (developed by Hublot’s R&D department under the supervision of its director Mathias Buttet), according to Zenith a new material resembling an extremely solid metal foam which features superb technical advantages such as a low density of just 1.6 kg/dm3, which is 2.7 times lighter than titanium, 1.7 times lighter than aluminium and 10% lighter than carbon fibre.

The material is unsual, but this is something that I think befits Zenith's tradition, as long as one keeps in mind that innovation does not equal 'classical design'. Zenith supplied us with a few life shots:









The first 10 watches of the new Zenith Defy Lab series are released as a special edition, each single watch in a one-off design: 5 different colours, with either rhodium or gold plated hands an indices. They are already sold to distinguished collectors.



I shall write up a more an in-depth report on this outstanding technical achievement by Zenith in a few days - stay tuned!

But right now let me close with Jean-Claude Biver's words: “Without tradition, there is no future”, but also “Without innovation, there is no future”.

There is nothing to add!
