Patek Philippe Grand Complications 5140

The Patek Philippe Reference 5140 is a perpetual calendar wristwatch, succeeding the highly regarded Reference 3940. It maintains the classic Patek Philippe perpetual calendar layout, featuring day, date, month, leap year, and moon phase indications. The 5140 was introduced with a slightly larger case diameter than its predecessor, reflecting contemporary preferences while retaining a traditional aesthetic. This reference was produced from 2006 to 2019. This reference is powered by the ultra-thin self-winding Caliber 240 Q, known for its micro-rotor construction which allows for a slender case profile. The movement provides a power reserve of 48 hours. The watch is presented in 18k white gold, rose gold, or yellow gold cases, measuring 39 mm in diameter and 8.5 mm in thickness, and is fitted with a sapphire crystal. It offers water resistance to 30 meters. The bezel is concave and polished. The 5140 appeals to collectors seeking a modern perpetual calendar with a direct lineage to Patek Philippe's established complications. Its production run saw various dial configurations, including opaline and silvery finishes. The watch is typically paired with a leather strap and a deployant clasp, consistent with Patek Philippe's classic offerings. It includes a 24-hour indication as part of its perpetual calendar display.
