The Royal Oak Tourbillon - case in stainless steel - is an exceptional timepiece, primarily because of its complications.
It has a 1 minute Tourbillon located at the 6 o'clock position, and a 30 minute chronograph / stop-watch function.
The chronograph is fitted with a titanium lever which gets rid of the “jumping chronograph hand” issue.
The Audemars Piguet Royal Oak Tourbillon Chronograph is animated by a manually wound movement whose balance wheel beats at a pace of 21,600 vibrations per hour.
The Tourbillon completes a single rotation each hour, as its cage bears the balance wheel, and the components of the escapement.
