Zenith, the iconic watch manufacture who introduced the Swiss watch industry’s first ever automatic chronograph El Primero in 1969, now presents a new innovation: The world’s most accurate mechanical watch equipped with a new oscillator that beats at 108,000 VpH (15 Hz)!
Zenith's latest creation, the Defy Lab is the first and only mechanical watch embodying both an evolution and an improvement of the sprung balance principle presented in January 1675.Powering the Defy Lab is a highly exceptional self-winding mechanical
movement featuring a high precision, high beat oscillator that
represents a major innovation in the watch industry since the 1675
invention of the balance and hairspring principle by scientist
Moreover, it remains accurate far beyond 24 hours of operation (the moment when mechanical watches begin to lose their energy and thus their accuracy). This new oscillator maintains the same degree of precision for 95% of its power reserve.
Insensitivity to temperature gradients, gravity and magnetic fields eliminates the key weaknesses of the current balance-and-spring assemblies that are subject to deformation and/or dilatation, thereby leading to diminished precision.
The acknowledged champion of high-frequency chronographs, thanks to its fabled El Primero movement, the Zenith brand shifts up to ultra-high accuracy with the Defy Lab watch representing a true quantum leap in terms of performance and engineering.
Moreover, the new Zenith Oscillator takes the form of a single piece without any mechanical linkages, instead of the customary 30 or so parts that require assembly, adjustment, setting, testing and lubrication.
Its functionality has been considerably optimized: the Zenith Oscillator is an all-of-a-piece organ without mechanical linkages that replaces the 30 or so ordinarily assembled, adjusted, regulated and controlled parts.
The absence of conventional mechanical couplings eliminates contact, friction, wear, slack, lubrication, assemblies and dispersions. The wheel replacing the escape wheel has a specific design and its cycle does not correspond to the traditional behaviour of a Swiss lever escapement. It is made of silicon showing superficial oxidation.
The precision of the Defy Lab “naturally” meets the requirements of the ISO-3159 standard and in fact exceeds them. Never before in watchmaking history and in no chronometry contests has a serially produced mechanical watch ever attained such a degree of precision.
The Defy Lab is a watch bearing the “viper’s head” emblem, meaning it is chronometer-certified by Besançon Observatory on behalf of the International Bureau of Weights and Measures.
The Zenith Oscillator is in the process of being certified as non-magnetic and meets high criteria in terms of temperature variations.
The watch obviously meets the magnetic criteria of ISO-764. It even exceeds them by nearly 18 times (the completed watch), that is to say 88,000 Amperes per meter or 1,100 Gauss. And there is no need for an extra inner case to achieve this.
This characteristic is a nod to Zenith’s longstanding aeronautical tradition, notably featuring the first victorious Channel crossing by Louis Blériot in 1909 wearing a Zenith watch, as well as the extraordinary feat accomplished by Felix Baumgartner in 2012 – the highest human freefall jump from an altitude of 38,969 metres. In the process, he became the first man to cross the sound barrier in freefall, again with a Zenith watch on his wrist.
It is poured into a mould where a procedure internally developed by Hublot transforms it into an open-pore metal foam. These interspaces are then filled with an extremely light special polymer resistant to ultra-violet rays and anti-allergenic when in contact with the skin.
