Notes
The Impressive Diamond Setting:

At its heart beats the calibre 642P, an ultra-thin hand-wound mechanical movement measuring just4.5mm thick, equipped with a flying tourbillon and astronomical moon phase at 6 o’clock. In a delicate modern flourish, the black-fringed tourbillon cage and black moon disc of fer elegant contrast to the diamond brilliance, tracing a figure 8 pattern symbolizing good luck. This rare collector’s piece represents a transcendent fusion of mechanical complexity and artistic brilliance—a testament to
Piaget’s unrivaled expertise in both watchmaking and jewelry arts.
