The Patek Philippe reference 5101, known as the 10 Day Tourbillon, is one of the manufacture's most technically significant shaped watches, combining exceptional mechanical innovation with the distinctive Art Deco styling of the Gondolo collection. Introduced in 2003, it is powered by the manually wound Calibre 28-20/222, developed to deliver an impressive ten-day power reserve while maintaining exceptional chronometric performance. The movement incorporates a one-minute tourbillon, visible only through the sapphire crystal case back in keeping with Patek Philippe's long-standing tradition of concealing the regulating mechanism on the dial side. A linear power reserve indicator and small seconds complete the elegant display, reflecting the watch's emphasis on both technical excellence and practical functionality.

Produced in highly limited numbers in platinum, white gold, rose gold and yellow gold, the reference 5101 occupies a unique position within the modern Gondolo family. Its elongated rectangular case, inspired by Patek Philippe's historic shaped watches, provides an ideal canvas for one of the manufacture's most sophisticated manually wound movements. Today, the 5101 is regarded as one of the landmark references of the early twenty-first century, admired for its combination of extended autonomy, tourbillon precision, architectural design and exceptional hand finishing, making it one of the finest examples of modern Patek Philippe haute horlogerie.
