Twenty-4
The Patek Philippe Twenty-4 is the brand's signature women's timepiece, introduced in 1999 as a rectangular bracelet watch designed to accompany the modern woman around the clock — from professional engagements to evening occasions — as the name implies. The Twenty-4 draws on the rectangular case tradition shared with Cartier's Tank but executes it with Patek Philippe's characteristic refinement: integrated steel or gold bracelet with a smooth, beveled case, clean dials with Arabic numerals or diamond hour markers, and a slim quartz or mechanical movement. The original Twenty-4 in steel with diamonds became one of the most commercially successful Patek Philippe references of the early 2000s. In 2018, Patek Philippe introduced the Twenty-4 Automatic, ref. 7300/1200A, powered by an automatic caliber in a larger 36 mm case — marking the collection's first automatic movement and significantly broadening its appeal among collectors who prize mechanical calibers. Pre-owned Twenty-4 references span quartz and automatic examples across yellow gold, rose gold, white gold, and steel, with varying degrees of gem setting. The collection represents an accessible point of entry into pre-owned Patek Philippe ownership for women's watch collectors. DeMesy & Co. in Dallas has authenticated pre-owned Patek Philippe Twenty-4 references since 1987.
