AUTOMATIQUE

THE PRESENTATION OF THE OCTA AUTOMATIC MOVEMENT IN 2001 HAS MARKED A TURNING POINT AND PROVED THAT THE WATCHMAKING REVOLUTION OF THE 21ST CENTURY WAS UNDERWAY. EFFICIENT IN ALL RESPECTS, IT HAS UNDERGONE ONLY THREE EVOLUTIONS DURING ITS 20 YEARS OF OPERATION. THE MOST RECENT ONE CONCERNS THE WINDING AUTOMATION SYSTEM. IT HAS MOVED FROM BI-DIRECTIONAL TO UNIDIRECTIONAL WINDING, WHICH IS MORE EFFICIENT TO GUARANTEE THE RAPID TENSIONING OF THE LONG SPRING OF THE BARREL.
