Patek Philippe Travel Time Unique Piece – 4864/1J-001

Patek Philippe 4864/1J-001 is a rare and opulent ladies’ dual time wristwatch, crafted in 18k yellow gold and distinguished by its richly detailed dial, cabochon-set pushers, and woven gold bracelet. This reference, part of Patek Philippe’s Calatrava Travel Time collection, features a 30 mm case with a hobnail-patterned bezel and a snap-on caseback. The white dial is adorned with gold Breguet numerals, diamond hour markers, and two red subdials—one for the 24-hour second time zone and another for running seconds. The gold feuille hands and railway minute track enhance legibility while maintaining elegance. Adding to its visual richness are cabochon sapphire-set pushers at 8 and 10 o’clock, which allow independent adjustment of the second time zone, and a matching cabochon-set crown.
Inside, the watch is powered by the manual-winding caliber 215 PS FUS, stamped with the Geneva Seal, featuring 18 jewels, a Gyromax balance, and a free-sprung flat balance spring. It beats at 28,800 vibrations per hour and offers a power reserve of approximately 44 hours.
