The caliber 240 Q movement beneath the black sunburst dial of this platinum 5140P-013 delivers perpetual calendar complications through an ultra-thin architecture that remains Patek Philippe's most celebrated achievement in mechanical engineering. Housed within a 37mm platinum case, this Grand Complication demonstrates the Geneva manufacture's mastery of integrating day, date, month, leap year, and moonphase indications into a movement measuring just 3.88mm thick. The black sunburst dial creates dramatic contrast against the white gold applied hour markers, while the sapphire crystal reveals the intricate calendar mechanisms that will accurately track celestial and temporal cycles until the year 2100.
