Key Features:

• The Tourbillon Complication: Located at 6 o'clock, the tourbillon compensates for the effects of gravity on the escapement. The cage is remarkably light and serves as the small seconds indicator, showcasing the mechanical heartbeat of the watch.

• Calibre 978: This in-house movement is a descendant of the calibre that won the 2009 International Chronometry Prize. It features a large balance wheel for improved stability and precision.

• Jewellery Aesthetics: The "Jewellery" designation refers to the meticulous gem-setting on the bezel and lugs, which enhances the 18K pink gold architecture. The light-diffusing properties of the grey Mother-of-Pearl dial provide a shimmering, iridescent backdrop.

• 39mm Presence: At 39mm, this watch offers a more significant presence than the standard 34mm or 36mm Rendez-Vous models, making it a statement piece for collectors who appreciate "oversized" high-complication jewelry watches.

• Artistic Finishing: The movement is visible through a sapphire crystal case back, revealing circular graining, Côtes de Genève, and a skeletonized gold oscillating weight.

• Durability: With a 5 bar water resistance rating, it offers slightly more protection than the standard 3 bar dress watch, though it remains a delicate high-jewelry instrument.
