This Patek Philippe World Time reference 5130/1G-010 carries one of the maison's most enduring complications in one of its most traditional forms. Its self-winding movement drives the world time display, a format long associated with Patek Philippe and one that keeps this reference central for collectors who want the complication without later departures in layout. White gold gives the case a restrained presence at 39.5mm across and 9.4mm thick, a proportion that keeps the watch elegant on the wrist. The black dial sets the city ring and 24-hour display into sharper relief, which suits a reference built around legibility across changing time zones. Within the line, the 5130 stands as the direct continuation of the classic Patek world time formula, preserving the rounded case and balanced dial architecture that made the reference an anchor for the complication in modern production.
