Patek Philippe 5110J "World Time"

The Patek Philippe 5110J, known as “World Time,” stands as one of the most recognizable icons of modern Swiss watchmaking. Launched in the early 2000s, this model captures the spirit of travel and precision timekeeping. Its refined dial, surrounded by the names of 24 cities around the world, allows you to read the time simultaneously across all time zones, making it the perfect companion for those who love to travel in style.

The Mechanics Behind an Iconic Complication

The automatic caliber 240 HU movement, visible through the sapphire crystal caseback, exemplifies high-precision mechanical engineering. The “world time” function is based on Louis Cottier’s invention from the 1930s, which Patek Philippe elevated to the highest standards. The pusher at 10 o’clock allows intuitive time zone adjustment, while the 18k yellow gold case lends a touch of classic elegance. The guilloché dial enhances the visual experience, offering unparalleled refinement.
