Repeater watch Breguet and Audemars Piguet

A repeater is a mechanical watch that chimes the time on demand, by activating a trigger or push button. There are different types of repeaters, chiming simply the hours or striking time down to the minute. For instance, a quarter repeater strikes the hours on one tone and then the quarter hours on another. A 5-minute repeater strikes the hours and then the number of 5-minute intervals elapsed. A minute repeater strikes the hours on one tone (low pitch), the quarters by a sequence of 2 tones (high pitch – low pitch) and the minutes with a second tone (high pitch).

The Breguet Tradition Minute Repeater and Tourbillon. The gongs (another invention of Abraham Louis Breguet to replace the bells in use previously) are shaped across the movement instead of circling it. To amplify the sound propagation towards the outside, the hammers are unusually striking vertically from the movement towards the sapphire crystal.

The Audemars Piguet Royal Oak Concept SuperSonnerie presented at SIHH 2015 features an innovative ‘sound board’ to which the gongs are attached. Its principles is similar to that of stringed music instruments to amplify the sound of the repeater http://www.tarawatch.co/audemars-piguet-fake-55.html.
