This Audemars Piguet Royal Oak Manual Winding Tourbillon watch in yellow gold features a 44mm case, white guilloche dial, and a crocodile strap. The Audemars Piguet Royal Oak Manual Winding Tourbillon also features a hand winding tourbillon movement with chronograph function and sub seconds.

The Audemars Piguet Royal Oak Tourbillon Chronograph watch is an exquisite example of haute de gamme watchmaking. Audemars Piguet has taken the celebrated form of the Royal Oak watch and enriched it with the most celebrated complication in all of watchmaking. The tourbillon, invented at the turn of the 19th century, represented an ingenious triumph over the negative effects of gravity upon the escapement of pocket watches. At the same time, virtually overnight, the tourbillon came to represent a pinnacle of horlogical technique that only an
accomplished handful of watchmakers were capable of realizing. Of course, the house of Audemars Piguet, in its rich 125-year plus history, has made elite complications such as the tourbillon an integral part of their repertoire, producing some of the most beautiful ever made.

The Audemars Piguet Royal Oak Tourbillon Chronograph watch 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. The chronograph mechanism, enriched with a 30-minutes
counter, is fully integrated into the movement architecture (as opposed to being modular) and is controlled by the traditional means of a column wheel; this method is de rigeur on the finest chronograph watches, and ensures that the action of the chronograph mechanism is of the utmost smoothness and precision.
