A New Era of Precision: Zenith Defy Inventor

With its disruptive new "Zenith Oscillator" control system, Zenith is revolutionizing mechanical watchmaking. High frequency, chronometric precision, reliability and stability: the oscillator developed and patented by the Manufacture replaces the traditional sprung balance used for more than three centuries.

Beating at the extremely high frequency of 18 Hz (compared with the usual 4 Hz) and endowed with a comfortable two-day autonomy, Defy Inventor owes its exceptional properties to a disruptive technology: the single-piece Zenith Oscillator developed and patented by the Maison.

Its properties notably include increased reliability, given that this unique ultra-thin element (0.5 mm) replaces the 30 or so components of a standard regulating organ and thus eliminates contact, friction, wear and deformation; and secondly, stability, since it is made of monocrystalline silicon and therefore insensitive to temperature variations and magnetic fields.

Its powerful stature is carved from ultra-light materials: brushed titanium for the 44 mm diameter case, Aeronith for the textured bezel. This lightest aluminium composite in the world was developed using an exclusive high-tech process. Three times lighter than titanium, made of open-pore aluminium foam stiffened with a polymer, Aeronith is easily forgotten when worn, while asserting a unique modern style.
