Ateliers deMonaco’s Oculus Petite Minute is powered by its own in-house developed and patented Xtreme Precision Tourbillon movement. This movement encapsulates a unique hybrid between the craftsmanship from the past and the precision and technology of the future, delivering one of the most accurate Tourbillon movements in the world today.

Five years ago, Ateliers deMonaco announced the launch of its in house developed Grand Tourbillon Xtreme Precision, regulated to have a tolerance between 0-2 seconds/24H, and making it one of the most precise Tourbillons in the world.

An oculus denotes a circular opening in an otherwise solid dome or wall originating out of the Byzantine and neoclassical architecture that allowed light to come through and subsequently would naturally draw the attention to this opening of light. It is also known as an “oeil de boeuf” in French or simply a “bull’s-eye“. A sapphire bridge holds the 60 seconds Tourbillon’s cage as the bull’s eye of the further solid and more classical looking Côtes de Geneve decorated dial.

This exceptional timepiece boats a unique case design – 33 components to allow for contrasting hand-finishing, blend of titanium and 18K gold with recognizable convex lines.

The in-house developed, manufactured and patented movement incorporates Silicium and precise manufacturing methodology like LIGA and DRIE for 10 times higher accuracy, all leading to a regulation of 0 / +2 seconds per 24H for every time piece. This precious movement is again highlighted by the iconic 18K gold Rotor with unique ATELIERS DEMONACO shield, hand guilloché finishing, decorated front & back.
