Breguet

During a visit to the Breguet Boutique at the Bellagio in Las Vegas, I spent some time listening to the Breguet 7800 La Musicale.  It was impressive and sounded like a miniature wind-up music box.  Both on and off the wrist the sound was very clear.  And was very impressive in a specially designed wood case made of alpine spruce that acts as a soundboard to amplify the musical song played by the watch.
Is anyone familiar with the song that the Breguet La Musicale is playing?  Any guesses?

Here's a video I made so you can see the dial movement and hear the La Musicale:

I have to confess that I'm disppointed by the sound volume of the watch which is low when you don't use the wood piece to improve it.

Thanks Ed!
