Emmanuel, known as quattro on WatchProSite, delves into the fascinating and often overlooked history of double-signed Patek Philippe dials. His meticulous research uncovers the little-known collaboration with Belgian retailer Louis Lörtscher, providing valuable context for collectors interested in rare and historically significant timepieces beyond the more commonly recognized partnerships. This exploration highlights how unique retailer signatures can reveal hidden chapters in horological history.

Yesterday, after finishing my post about the partnership between Patek Philippe and the Grogan Company of Pittsburgh, Pennsylvania, I looked for other examples of the ref. 1401 on display at the Patek Philippe Museum, whose double-signed dial had piqued my interest.

It led me to come across this watch sold by Christie's in 2017, whose dial is signed "LörTscher" at 6 o'clock, with an unusual script:

  • The L extends under the other letters.
  • And the horizontal bar of the T extends above the R and the S.

Ref. 1401 manufactured in 1939 (movement no. 833'109, case no. 618'601) and signed Patek, Philippe & Co, Genève, retailed by Lörtscher

Intrigued by this name unknown to me, I began digging and discovered another  very little-known and documented collaboration


the one Patek Philippe had with Belgian watch retailer Louis Lörtscher.


As the following photos of a ref. 130 show, the Lörtscher boutique (“Horlogerie LörTscher”) was located in Brussels, Rue Montagne de la Cour, 81.

Here's a view of the rue Montagne de la Cour as seen from the Place Royale. Number 81 corresponds to the building on the left which forms the corner with the Place Royale.

Now, here are the other Patek Philippe timepieces  I could find featuring such a double signed dial with “LörTscher ”.



REF. 96 (?) FROM 1939

The photo shows that the “Horlogerie LörTscher” was at some point taken over by the Ditesheim brothers (“DITESHEIM Frères, Succ.”), who, as far as I know, founded the Movado watch brand in 1881.

REF. 491 IN 18KYG WITH Cal. 9-90 FROM THE 1930s

I know that this is a verynichepost, but I personally love to learn as much as I can about this beloved brand (I mean Patek Philippe).

And, hopefully, some of you will share my interest.

Thanks for reading.

About the Patek Philippe Complications Ref. 130

The Patek Philippe Reference 130 is a significant chronograph model, notable for its classic design and the various configurations in which it was produced. While many examples feature a standard chronograph layout, specific iterations, such as those with split-seconds functionality, represent a higher echelon of horological complexity within the reference. The model is recognized for its balanced proportions and the legibility of its dial, making it a favored choice among collectors seeking vintage Patek Philippe chronographs.

This particular example of the Reference 130 is distinguished by its yellow gold case, measuring 33mm in diameter. It houses a manual-winding movement, typical for chronographs of its era, and is fitted with a crystal, likely acrylic or sapphire depending on the specific production period and any subsequent servicing. The case construction and movement finishing adhere to Patek Philippe's high standards for precision and durability.

Collector interest in the Reference 130 is driven by its historical importance as an early chronograph from the brand and the rarity of certain dial and complication variations. The presence of unique characteristics, such as Breguet numerals, specific dial signatures, or the absence of a tachymeter scale, can significantly influence its appeal. The reference appeals to those who appreciate the foundational designs of Patek Philippe's chronograph lineage.

Predictably, 491 for me. Were you aware of this Belgian watch dealer and of this collaboration? Best, Emmanuel

Always learning here. They've got a very distinctive signature. I quite like the co-signed pieces. They're not to everyones tastes, I know...

For whatever reasons, I like “Walser Wald”, “Serpico y Laino”, “Gobbi Milano” or even “Grogan Co.”, but am not enthralled by “Tiffany & Co.” or, I have to be honest, “LörTscher”... Best, Emmanuel
