GLau's meticulous comparison of Patek Philippe Ref. 5131G World Time enamel dials highlights a fascinating, often overlooked variation in their appearance. By photographing 'chrome' versus 'non-chrome' dials under identical lighting conditions, GLau provides compelling visual evidence that sparks a deeper inquiry into the intricate art of enameling. This post invites collectors to explore the subtle nuances that distinguish these highly coveted timepieces.
Yours truly capturing the two different enamel dials for 5131Gs






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. This movement provides a power reserve of 48 hours and drives the World Time complication, allowing the wearer to simultaneously view the time in 24 different time zones. The case is fitted with a sapphire crystal, ensuring durability and clear visibility of the detailed dial. Water resistance is rated at 30 meters, suitable for everyday wear. 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.
Great post again Gordon! I for one prefer the non-chrome version!
I wasn't aware of this until you pointed it out the other time, and in fact I never even heard the term "chrome" being officially used by Patek for the 5131! So perhaps, creating this effect wasn't even deliberate on the part of the enamelers? Thanks again for a good post! Cheers.
also non-chrome given its more traditional colors. 😇
Rolex root beer 🍺 to the GTG ! Perhaps the post should be moved to the Rolex forum ? 🤣
I’m pretty sure the difference relates to the thickness and opacity of the enamel and show through from the base gold disc. I see the effect on my Tellurium and at certain angles and lighting the texture of the disc and light reflecting is clear to see.
on another note, funny you are sporting a two-tone Rollie in your world time GTG
