Royal Oak Offshore Selfwinding Tourbillon Chronograph

Audemars Piguet 2011

Tourbillon Chronographe Automatique Royal Oak Offshore / 2011

A 100% in-house made movement.

Calibre 2897 is a selfwinding movement entirely developed and produced by Audemars Piguet

The peripheral oscillating weight

Automatic winding is ensured by a peripheral oscillating weight in 950 platinum, mounted on ball bearings. Such a choice shifts the weight of the rotor to the outer edge of the movement, thereby improving winding speed. Moreover, because of its position on the periphery of the movement, it does not increase the overall thickness.

It also offers the additional aesthetic advantage of entirely freeing up the reverse side of the movement and thus providing full views of the mechanism, and particularly its column wheel, through the transparent back of the watch.
