The Breguet Réveil Musical for Only Watch 2011 is another incarnation of the Réveil Musical that Breguet introduced at Basel 2010. That watch plays a tune through a disc with pins alternately acting on 15 metal teeth of a comb. An engine-turned metallic glass membrane amplifies the frequencies and does double duty ensuring water resistance. By drilling holes in the gold case the sound is able to emanate for better acoustics. Breguet doesn’t reveal the materials used for the comb and the membrane but if you get a chance to hear this watch do its stuff, you will see why Breguet wants to keep the recipe of their secret sauce under wraps.

To start the music, you engage the push piece located at 10 o’clock. Or you can get the notes to perform by pre-setting the alarm to go off. The watch doesn’t just sing, it also dances. The entire dial does a complete 360-degree turn during the 20 to 25 seconds the notes are played.  And just so you don’t get cut off midstream, the music won’t start unless there’s sufficient power to complete the entire action, which you can track through the power reserve indicator at 3 o’clock. The musical theme continues to the case band with its musical notes and to the seconds hand whose tail end displays a treble clef.

The Réveil Musical houses the Breguet Caliber 777 movement with a silicon escapement and Breguet balance-spring.

What Breguet has done with their contribution to Only Watch is take the delightful Réveil Musical and make some changes that are cosmetic but nonetheless significant. The watch now plays the tune “Castle in the Sky” and the dial shows a child’s hand that turns all the way round the dial to meet the adult hand on the flange. Breguet says this image represents inter-generational solidarity and support for research on Duchenne muscular dystrophy. The pose reminds me a lot of Michelangelo’s Sistine Chapel image.

An amazing piece of kinetic sculpture that also makes music, the Réveil Musical is a wonderful watch to help fund a worthy cause.
