It takes ingenuity and precision to strike the perfect chord.


The Royal Oak Concept Supersonnerie presents a newly developed case construction that prevents sound absorption, boosting amplification. In traditional minute repeater technology, the gongs are fixed to the plate. In the Royal Oak Concept Supersonnerie they are attached to a new device, a material spread beneath the movement that acts as a soundboard. Now, the gongs transmit vibrations directly to the soundboard – not to the mainplate. The technology functions like the upper body of a guitar. With the vibrationtoair system improved, sound quality, tone and amplification are richer.

Minute Repeater

This complication comprises the greatest number of parts, often more than 400. The minute repeater sounds the time by hammers hitting hardened steel gongs. It indicates, on request, the hours by a series of strikes on the low-pitched gong, quarter hours by striking the low/highpitched gong and additional minutes in relation to the latest quarter hour by striking the highpitched gong.


The number of gongs and hammers tuned to perfection by ear.


The century the repeater was invented. Created to hear the time, rather than look at your watch, after the sun went down.

Time Keeping

It is a feat of horological mastery to be able to tell the exact time to within one-fifth of a second; to strike the hour, quarter hour and minute on demand; to display the position of the stars, and to supply the correct date with no need for adjustment in the coming century or two-all in the space of a tiny case that houses an even tinier mechanism.

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.
