GLau, a recognized expert in haute horology, delves into the intricate world of Patek Philippe's World Time Ref. 5131, specifically comparing the white gold (G) and rose gold (R) enamel dials. His detailed analysis focuses on the nuanced differences in enamel artistry, offering a connoisseur's perspective on color gradation versus contrast. This exploration is crucial for collectors seeking to understand the subtle yet significant distinctions in these highly coveted timepieces.
Both the G and R maps contain lovely colors (with G containing more colors), but the G has better color gradations which is important to me because IMO better skills are required. With less gradations, R therefore has more color contrasts.
Overall, whether G or R, it comes down to personal taste of whether color gradations vs contrasts being one’s preference.
By the way, having met Anita Porchet in person in Singapore during the Grand Exhibition, the master told me that she and her team were responsible for the G and P. www.watchprosite.com
What is your preference between G and R and why ?
Yours sincerely,

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.
not only since I own the R but my preference was (right after the enamel dial ) the colour of the case material, i m a sucker for rose gold . The differences you ve mentined are noticable under high magnification and these dials are ALL magnificent as soon are hit by the light especially by the Sun . Worshipper of PP WTs
Not sure I follow the differentiation you are making since there are such drastic differences between the dials R to R and G to G due to the process. I would say the G in your photos seems to have a lot of air bubbles in the enamel which is unusual? Not something I associate with AP dials.
On the other hand, R has more vivid and high contrast colours, especially the initial version like Russell's one. However, the colours transition of R is more abrupt. Personally I like G a bit more than R, as the grass next door is usually greener.
My slight preference is for the R though, mainly because of the case color (as I already have the P in white). Thanks for some great pics! ;-)
Also interesting that there are different teams that work on the G+P than R+J.
So which team is responsible for R and J? I thought all done by Anita P.
