The Manufacture’s emblematic moon-phase complication finds its place on this timepiece, which is powered by the calibre 6654.P. Reintroduced by Blancpain in 1983 in the wake of the quartz crisis, this complication enabled the brand to demonstrate that a mechanical timepiece was the product of extraordinary expertise and that quartz could never replace a complex mechanical watchmaking creation. It thus came to symbolise the revival of mechanical watchmaking. Blancpain’s immediately recognisable moon phase is found on the calibre 6654.P, which not only has a 72-hour power reserve (thanks to its two barrels), but also a secure movement, enabling the wearer to adjust the calendar indications at any time of day without damaging it. Adorned with traditional Fine Watchmaking decorations, such as bevelling, circular graining and snailing, this calibre is visible through a sapphire crystal case back and incorporates a silicon balance-spring, making it impervious to magnetism.
