Patek Philippe World Time Reference 5110J

Partially verified

The Patek Philippe Reference 5110J is an automatic wristwatch with a world time complication, first released in 2000. The watch is constructed from yellow gold with a diameter of 37mm and features a mid-case with integrated crown guards. The dial displays local time centrally, surrounded by a 24-hour ring and a rotating disk listing 24 global locations, with a pusher used to adjust the time settings. The center of the dial is decorated with an intricate guilloché pattern. Power is provided by the Patek Philippe Calibre 240, an automatic movement featuring an off-center micro-rotor, visible through an exhibition caseback. The watch is fitted with a black alligator strap and an 18K yellow gold deployant clasp, and it is protected by a sapphire crystal.

Object description

Case and Dial Construction

The Patek Philippe Reference 5110J features a 37mm diameter case crafted from yellow gold. The design incorporates a flowing mid-case architecture that integrates crown guards surrounding the winding crown. The watch is equipped with a sapphire crystal and an exhibition caseback, providing visibility into the movement components.

The dial surface is finished with a detailed guilloché pattern. Functionally, the dial operates via a rotating disk on the periphery that displays 24 cities representing different time zones, paired with a central 24-hour ring to indicate time in each location. A pusher is integrated into the case to facilitate the adjustment of the local time.

Evidence for this section
  • “Fashioned from yellow gold with a flowing mid case that forms elegant crown guards”
  • “measures 37mm in diameter”
  • “The center of the dial has a beautiful intricate guilloché pattern”
  • “Displaying 24 time zones on a rotating wheel at the periphery of the dial, the local time is changed simply by pressing a pusher”

Movement and Mechanics

The timepiece is powered by the Patek Philippe Calibre 240. This is an automatic movement characterized by the use of an off-center micro-rotor, a design feature often utilized by the maker. The movement is visible through the exhibition caseback of the watch.

The Calibre 240 is described as a significant mechanism within the manufacturer's range of references, noted for its usage in other prominent models in the brand's production history. Its configuration supports the integrated world time complication that identifies the reference.

Evidence for this section
  • “features an automatic winding micro-rotor Calibre 240”
  • “The Calibre 240 is one of Patek’s most legendary, finding itself in many of Patek’s most notable references”

Associated Components

The watch is presented on a black alligator strap. This strap is secured to the wrist with an 18K yellow gold deployant clasp, consistent with the yellow gold construction of the watch case. These elements complete the aesthetic of the 5110J as configured by the maker.

The reference is noted as the first world time watch released by the brand following the Reference 2523, establishing a design language that informed subsequent modern world time models produced by Patek Philippe.

Evidence for this section
  • “Set on a black alligator strap and completed with an 18K yellow gold deployant clasp”
  • “the 5110 was the first world time released since the Reference 2523”
  • “set the blueprint for Patek’s modern world time case styles”

Open research questions

  • Are the city names on the dial disk specific to a particular production year or variant of the 5110J?
  • Does the specific serial number of the movement indicate an early production run of the Calibre 240?
