Patek Philippe 5110G-001 features the automatic Caliber 240 HU movement, enabling simultaneous display of 24 time zones through a central dial, rotating 24-hour ring, and city disc. Encased in a 37 mm white gold case, the watch includes a push-button adjustment system at 10 o’clock for quick time zone changes. The micro-rotor construction supports a slim profile while delivering approximately 48 hours of power reserve, with movement finishing visible through the sapphire case back.

Its compact proportions and precise functionality make the 5110G-001 a highly practical world time reference. The watch delivers clarity in global timekeeping while maintaining the mechanical reliability and refined construction expected from Patek Philippe.

Alternative References & Configurations

The 5110 family was produced in several precious-metal configurations:

* 5110J-001 — 18K yellow gold; silver-toned/guilloché World Time dial.
* 5110G-001 — 18K white gold; silver guilloché dial. Primary configuration.
* 5110R-001 — 18K rose gold; silver-toned/guilloché dial.
* 5110P-001 — platinum; distinctive platinum configuration with guilloché World Time dial.

The 5110G-001 is historically significant because the 5110 marked Patek Philippe’s return to the World Time wristwatch in 2000 after a 35-year absence. It was subsequently replaced by the Ref. 5130 in 2006. Phillips and Christie’s both independently identify the 5110G-001 as an 18K white-gold, 37 mm World Time powered by Calibre 240 HU.

Reference distinction: The 5110G-001 belongs to an earlier generation of Patek Philippe World Time watches than the 5230P-001. Its 37 mm white-gold case, winglet-style lugs, silver guilloché dial and Calibre 240 HU define this specific configuration.
