Emmanuel, known as quattro on WatchProSite, offers an intriguing look into the Patek Philippe 'Cabriolet' and its modern descendant, the Ref. 5099RG. His detailed comparison highlights the subtle yet significant design evolutions between the 1920s original and its 1999 reinterpretation. This exploration provides valuable context for understanding Patek Philippe's design philosophy and how historical pieces continue to inspire contemporary creations.

One of the timepieces on display in the Patek Philippe Museum which I find intriguing and exquisite is the “Cabriolet” which served as a source of inspiration for the modern ref. 5099RG.



The movement (based on a 9’’’ ébauche by LeCoultre & Cie) was manufactured in 1927 and the case in 1928

And the watch, which was made for Eberhard Milan, as evidenced by the signature at 6 o'clock on the dial, was sold on June 13, 1929.



The rectangular cabriolet case is made of yellow and white gold



And the side of the case is subtly engraved (sorry for the low quality photos of the case side).









The watch, with inventory no. P-1329, is on display with three other watches in the window no. 55 dedicated to the “Style années 20” (1920s style).





As stated in the catalog of the Museum, it was part of a series of three: its case number is 606 797, whereas the other two, the whereabouts of which are unknown, have case nos. 606 795 and 606 796.



It was probably acquired by the Patek Philippe Museum at the auction organised by Antiquorum in Geneva on April 10, 1994: lot 429.

Launched at the Basel Watch Fair in 1999, the ref. 5099RG-001 is directly inspired by the “Cabriolet” of the 1920s.

However, instead of being made of yellow and white gold, its case is made of rose and white gold.



The railroad track and numerals are identical to the original.

But the original pear-shaped hands have been replaced by sword-shaped hands, the numerals of the small seconds register have been removed and the brand signature has been modernised.

The hinges and the crown are also different. And, most importantly, the case flank isn't engraved.

I find the design and look of the watch quite stunning.

Even the pin buckle has a unique faceted design.

And one can only regret that this watch is so rarely seen, because the fit/look on the wrist is wonderful.

Our dear sham1 acquired his eight years ago.





I mean, how classy is this!

In 2005, Patek Philippe made a unique gem-set variant piece, ref. 5099/101-RG-001 for the Only Watch auction.

But I'm not going to lie: even though I love the original “Cabriolet” and the ref. 5099RG, I don't like this unique piece at all, as I don't like either the case or the dial.



The watch was sold by Antiquorum on September 22, 2005: lot 27.

In 2008, Patek Philippe created an additional two series of four Rare Handcraft pieces:

  • One series consisted of four pieces decorated with Art Deco designs as a nod to the era of the launch of the first “Cabriolet” in the lates 1920s: I have not been able to find images of these pieces.
  • The second series, also consisting of four pieces, featured delicate butterfly designs: they are shown below and were sold by Antiquorum on March 17, 2013: lot 121.

But let's not conclude this post with these not very appealing (to me) pieces: let's rather add a few more photos of the ref. 5099RG.

About the Patek Philippe Gondolo Ref. 5099

The Patek Philippe Reference 5099 is a limited-edition cabriolet-style wristwatch, drawing inspiration from a historical Patek Philippe timepiece from the late 1920s. This reference is notable for its unique reversible case design, allowing the watch to be worn with either the dial facing outwards or the solid case back presented, protecting the crystal. It represents a modern interpretation of a classic Patek Philippe design, appealing to collectors interested in historically inspired pieces with a distinctive mechanical feature.

The case of the 5099RG is crafted from 18k rose gold, featuring a rectangular shape that articulates the cabriolet mechanism. The watch is powered by a manual-winding mechanical movement, consistent with the traditional watchmaking ethos often found in Patek Philippe's more specialized or limited productions. The crystal protecting the dial is sapphire, ensuring durability and clarity.

This reference appeals to collectors who appreciate Patek Philippe's heritage and its ability to reinterpret historical designs with contemporary craftsmanship. The cabriolet function offers a unique wearing experience and a conversation piece, distinguishing it from more conventional timepieces in the brand's catalog. Its limited production further enhances its desirability among discerning collectors.

Hi Emmanuel, the cabriolet (convertible) design is a new lesson for me ! Thanks for the post !

It certainly has a vintage vibe to me and is unusually lovely 👍 Although different, the cover of the cabriolet reminds me of the “reverso” from JLC. Wonder 🤔 if Patek was also designing for polo players ?

My pleasure, Gordon.

I have seen no mention of a link with the Polo. Tania Edwards mentions “the charm of a time long gone, when etiquette demanded that a gentleman gave his companion his full attention”. I really can’t tell if this is the correct explanation. In any case, I find the design very special and appealing even if very sophisticated. Best, Emmanuel

An interesting model

I would personally have preferred a non polished top using technique such as perlage, for example, to avoid glare and complement the automotive theme.

You have a point:

I’ve never seen one in real life and in the wrist, and I think I wouldn’t like it if it acts as a mirror. Just another piece I have to look for, for a try on experience… Best, Emmanuel

I could totally see one on your wrist someday

I think I could too,

but I still have to see one in person: I would like to be sure that the watch doesn’t feel more sophisticated than classy. Have you seen one? If yes, how did you feel about it? Best, Emmanuel
