Its face is covered by monocrystalline sapphire set right into the case middle, itself in sapphire and 18K yellow gold, cut in twelve facets joined at the centre of the dial with a precision of 1/100th mm. Inside, a “skeleton” type Piguet movement with 1kK gold mainplate openworked and decorated by hand, protected by a dynamic waterresistant system in excess of 6 atmospheres. (CENTURY TIME)
