The Patek Philippe Complications reference 5131 is a World Time model, distinguished by its cloisonné enamel dial depicting a map of the world. This reference is part of a series that showcases Patek Philippe's expertise in both horological complications and traditional decorative arts, offering a functional travel watch with significant aesthetic appeal. It represents a continuation of the brand's long-standing tradition of producing World Time watches, updated with contemporary design elements and a self-winding movement. The 5131 is recognized for its intricate dial work, which varies depending on the specific metal and region depicted.

The watch features a 39.5mm case, available in various precious metals, housing the self-winding Caliber 240 HU.

The fixed bezel frames the intricate dial, contributing to the watch's refined profile.

As a World Time model with a cloisonné dial, the 5131 appeals to collectors who appreciate both technical sophistication and artisanal craftsmanship. Its limited production and the unique hand-finished nature of each dial contribute to its desirability within the secondary market. The reference fits into Patek Philippe's Complications collection as a high-end travel watch, offering a distinctive alternative to more traditional time-only or chronograph models. Variants typically involve different precious metal cases and corresponding enamel map depictions.

This timepiece features an 18k white gold case measuring 40 mm in diameter and 8.42 mm in thickness. It is powered by the ultra-thin self-winding caliber 240 Q, which provides a power reserve of 48 hours. The movement is visible through a sapphire crystal case back, while the front is protected by a sapphire crystal. The watch is water resistant to 60 meters.

The blue sunburst dial with its horizontal embossed pattern is characteristic of the Nautilus family, here featuring three sub-dials for the perpetual calendar indications. The integrated bracelet is also crafted from 18k white gold.
