At 41 mm in diameter and 12.7 mm in height, the platinum case of the 5271P-010 makes an immediate impression through its gem-setting alone: 58 baguette-cut diamonds on the bezel and lugs totaling 4 carats, complemented by a diamond-set fold-over clasp carrying an additional 22 stones. Interchangeable solid and sapphire crystal case backs offer a choice of presentation, and the case is water-resistant to 30 m.
The black lacquered dial is appointed with white gold applied faceted baton-style hour markers and a single baguette-cut diamond hour marker, while a tachymeter scale traces the outer edge. Powering the watch is the manually wound Caliber CH 29-535 PS Q, a movement that orchestrates a central chronograph hand, an instantaneous 30-minute counter, small seconds, perpetual calendar displays for day, date, month, leap year, and day/night indication, along with moon phases — all indicated by hands.
The shiny black alligator leather strap with square scales is hand-stitched and fastens with a diamond-set platinum fold-over clasp. Across the case, strap, and clasp, the watch carries a total of 81 baguette-cut diamonds amounting to 5.01 carats, making the reference 5271P-010 one of the most ornate expressions within the Grand Complications collection.
