Patek Philippe World Time 5110J Guilloche Dial in 18k Yellow Gold with Extract of the Archives

The story of the Patek Philippe World Time—historically known as Heures Universelles—is deeply intertwined with an era when international travel was still an adventure and crossing continents carried an unmistakable sense of glamour. Conceived during the early 20th century for diplomats, businessmen, and seasoned travellers, the World Time complication enabled its wearer to read all 24 time zones simultaneously at a glance—an extraordinary technical achievement for its day. Over the decades, the World Time evolved from a highly specialised travel instrument into one of the most admired complications in haute horlogerie. Combining mechanical ingenuity with beautifully balanced dial design, it came to represent not only technical sophistication but also a romantic vision of global travel that continues to captivate collectors today. Presented here is the Patek Philippe reference 5110J, with the "J" denoting its elegant 18k yellow gold case. Measuring a perfectly proportioned 37mm, the Calatrava-inspired case is beautifully sculpted, featuring integrated crown guards and Patek Philippe's patented world-time pusher at 10 o'clock. A single press of the pusher simultaneously advances the central hour hand, the 24-hour ring, and the outer city disc in one-hour increments, instantly recalibrating the display across all 24 time zones. It is a wonderfully intuitive and elegant mechanical solution, making one of watchmaking's most complex complications remarkably easy to use. Turning the watch over reveals a sapphire display case back showcasing the exceptional ultra-thin self-winding calibre 240 HU. Equipped with Patek Philippe's beautifully finished 22k gold micro-rotor, the movement is every bit as impressive as the dial it powers. The watch is fitted with a handsome Bulang and Sons leather strap and its original 18k yellow gold Patek Philippe pin buckle. Accompanying the watch is an Extract from the Archives confirming its sale in 2001.
