The hour hand remains hidden beneath the constantly moving minute hand, solely appearing at a deliberate press on a crown-integrated pushbutton. It vanishes as soon as the pressure is released – as too does the dual-time window display caught up in the same game of hide and seek.
Mechanical timepiece with a fully functional high-performance altimeter. Hours and minutes subdial at 8h, precision altimeter subdial displaying meters (or feet) at 2h, large-scale altitude indicator on the top of the dial.
The world’s first perpetual power reserve. An invisible photovoltaic component built into the sapphire crystal screen produces enough electricity under certain natural or artificial light sources to charge the phone. For the first time, a communication instrument can maintain the charge level of its battery in standby mode. Limited edition of 1911.
Wristwatch equipped with a traditional detent escapement, a mechanism usually designed to run in a perfectly stabilized position. Cylindrical balance-spring, anti-over-banking security device (balance wheel oscillating with excess amplitude).
First watch equipped with an assortment – balance roller, lever and escapement wheel – entirely made of silicon. Three times lighter than steel, this material is also more accurate, less energy-hungry and requires no lubricant.
The silicon device, based on the principle of flexible materials, uses the elasticity of blade springs to dispense with the pivot of the pallet arms leaving them literally suspended in space. The revolutionary «flying anchor» required seven years of research, development and improvements with Sigatec, a co-owned company specialized in silicon micro-components.
