Time Interval

One-fifth of a second accuracy takes years to master. It is to this day one of the most sophisticated complications in the watchmaking mechanism and one of the hardest to perfect. Several construction types have been developed, but the most prestigious and spectacular one is the columnwheel chronograph.

Laptimer

Developed at the design and technical department of Audemars Piguet, the Royal Oak Concept Laptimer Michael Schumacher features a pending patent covering its unique functionality, which is based on a mechanism incorporating no fewer than three column wheels. One column wheel, located at the six o’clock position, controls the chronograph sequence, while the two at the 12 o’clock position control the complex laptimer sequence. The gear train is driven by two mainspring barrels set in parallel which provide double the usual amount of torque and 80 hours of power reserve - and, to ensure exceptionally smooth operation the watch features specially developed conical gear teeth which mesh seamlessly and accurately at all points in the movement’s cycle for a perfectly linear torque transmission. A new oscillating wheel coupling mechanism has been developed for jerk-free action when the chronograph is stopped or started.

Chronograph

A chronograph is a standard watch fitted with an auxiliary mechanism that measures and displays continuous or discontinuous spans of time without affecting the watch’s time-keeping functions. A center chronograph hand is started, stopped and restarted at will, then returned to zero by actioning one or more push-pieces. It is both useful in daily life and remarkably complex in technical terms.

Split Second Hand

Split second chronographs are fitted with an additional seconds hand that can be stopped in its tracks in order to measure an intermediate, or to maintain a reference time.

Chiming

It takes ingenuity and precision to strike the perfect chord. The watchmaker will spend as long as required to ensure that the cadence of the strike is neither too fast nor too slow, and exactly equal on both hammers. Gongs will be tuned in order to play the clearest possible note.
