Description:

A total of 659 mechanical parts, 71 of them jewels, twelve patents and 21 functions and displays, including a perpetual calendar for the next 500 years, together with a perpetual moon phase display made of polished goldstone representing a star-studded night sky.
The Grande Complication has all the features needed to make it a pinnacle of watchmaking achievement.
Working inside the case are a chronograph and a highly complex minute repeater with an all-or-nothing piece slide.
This wonderful invention chimes out the time in crystal-clear tones, which are activated by the slide of the left-hand side of the case.
Two tiny, precision-made hammers are released and chime in hours, quarters and minutes on two gongs.
Developing the striking mechanism was a technical tour de force.
Initially, the chimes were inaudible outside the solid platinum case, so the glass was freely suspended on a platinum membrane to enable it to amplify the vibrations produced by the gongs via the sound transmission pin.
The beautiful tones are also influenced by the glass.
The case, too, finished in 18K gold, is first-class.
The Grande Complication has an automatic, self-winding movement and, despite the complex design of the case, is unaffected by superficial water splashes - water resistant to 30 meters / 100 feet.
