Between December 1931 and April 1932, eight Reverso cases, manufactured by Wenger, were sold to Patek Philippe with the authorisation of César de Trey, who had registered the brand name Reverso, and Jacques-David LeCoultre, who was one of the administrators of Patek Philippe at the time.

According to the registers, four of the cases were made in white gold, and the remaining four in a mix of white and yellow gold.

The watches were given the ref. number 106 and all eight watches were powered by movements based on LeCoultre ébauches and had different dial colors and layouts.

Only five of the eight watches are known, among which three belong to the Patek Philippe Museum.

Key Points from the Discussion

The Patek Philippe Reverso ref. 106 watches were produced with the authorization of Jacques-David LeCoultre, who was a board member of Patek Philippe at the time, underscoring the intertwined history of the two manufactures.
Despite Patek Philippe's historical production of Reverso-cased watches, current Patek Philippe President Thierry Stern has indicated that the brand would not produce modern Reverso-style watches, out of respect for Jaeger-LeCoultre's identity with the design.
While Patek Philippe did utilize Reverso cases, the patent for the Reverso mechanism has always belonged to Jaeger-LeCoultre, which also punctually sold cases to other brands like Cartier.
One collector recalls a Patek Philippe Reverso ref. 106 appearing at auction 15-20 years ago, noting that its value at the time was significantly less than many modern Patek Philippe references today.
The Patek Philippe Museum houses three of the five known Reverso ref. 106 examples, making it a crucial destination for enthusiasts interested in viewing these rare pieces.

I knew that there were some Patek Reversos but I don’t think I’ve ever seen pictures before. I’m sure I read an article in which Thierry Stern said that Patek could make modern reverso cased watches but it wouldn’t be appropriate. I guess they don’t need to tread on JLC’s toes and many people would think they were copying JLC, without knowledge of the history you have highlighted. All the best, Jon

It would be amazing to read a full history of the reverso watch. I am sure we are all aware of the 1933 Huber reverso, and I wonder how many other brands had utilised the reverso before JLC took command.
