MANUFACTURE AUTOMATIC MOVEMENTS
While some horophiles derive pleasure winding a manual movement each day, some wearers prefer the convenience of an automatic movement. Providing the watch is worn, it will continue to tick, a welcome attribute for many time-poor, business professionals.
Visually, the ASE (Automatic Schwarz Etienne) calibres appear similar to the company’s MSE (Manual Schwarz Etienne) calibres. This is because they also subscribe to the same patented modular design. Sharing the same main plate, the ASE calibres eschew one barrel in favour of a micro-rotor.
The micro-rotor, an off-centre oscillating weight, is thicker than a conventional rotor and yet remains compact, sitting within the space usually occupied by one of the MSE calibre’s barrels. Featuring highly efficient bi-directional winding, the micro-rotor doesn’t increase the dimensions of the calibre and, unlike traditional oscillating weights, it offers an alluring, unimpeded view of the movement.
All ASE calibres run autonomously for up to 86 hours. The variable inertia balance delivers notable precision, reliability and rate stability. The ASE calibres can also be used as base movements, serving to accommodate various modules.
