Boldly defying the sprung balance regulating-organ principle that has prevailed since 1675, and instead calling on cutting-edge technologies based on the latest research in horology and in the science of materials, the aptly named Defy Lab represents a major watchmaking breakthrough. Its new monolithic oscillator in monocrystalline silicon, coated with a silicon oxide layer, replaces the 30 or so components of a conventional regulating organ – and in doing so does away with all the stages normally required for the latter, such as assembly, adjustment, setting, testing and lubrication. Beating at the incredible frequency of 15Hz and boasting a generous 60 hours of autonomy, this revolutionary movement achieves a mean daily precision of 0.3 seconds, a degree of performance that it maintains for 95% of its power reserve. Insensitive to gravity and dispensing with any need for lubricants, the Defy Lab is triple certified: for its precision duly recognised by the Chronometer title awarded by Besançon Observatory; for its exceptional insensitivity to temperature changes far exceeding the ISO-3159 standard; as well as for its outstanding resistance to magnetic fields up to 1,100 Gauss, which is 18 times better than the ISO-764 standard. And to attire this distillation of innovation and technology, Zenith has chosen the world’s lightest aluminium composite, Aeronith.
This is the fifth time that Zenith has won a prize at the Grand Prix d’Horlogerie de Genève.
