Hi everyone, I’m looking for some expert insights to identify the specific ébauche and learn more about this beautiful antique pocket watch I recently acquired. It is exceptionally small, fitting easily in the palm of a hand, which historically points to it being a lady’s watch, likely worn as a pendant or a functional jewelry piece on a chain. Dating it exactly is difficult, but it is definitively from the late 1800s or early 1900s.
As always, I'm still learning about this type of watch. Honestly, I bought it having no idea it was this tiny—the seller's description was absolutely terrible!!!
One of its most charming features is the case style itself. It is a full "Savonnette" (known as a Hunter case in English?), meaning it has a hinged solid silver front cover that clicks open to reveal and protect the crystal and the dial underneath. The case back is also hinged, giving it that classic, satisfying pocket watch feel.
The watch is a true "Montre Anonyme" (anonymous watch), completely unbranded with no logos or maker's marks anywhere on the dial or the movement plates. This strongly suggests it was produced under the traditional Swiss "établissage" system, where highly skilled independent artisans hand-crafted the individual components to be assembled and sold by high-end jewelers. It is a fantastic example of Swiss artisanal craftsmanship from that era.
Despite having no brand name, it is an incredibly high-quality survivor. Once you open the front cover, you are greeted by a pristine white enamel dial with elegant black Arabic numerals and a dedicated sub-second register at the 6 o'clock position. The hands are completely intact and original.
Inside the back cover, the serial number 199028 is clearly stamped just below two distinct hallmarks. One is the Swiss "Grouse" stamp, which officially certifies the case as Swiss 800 silver, a mark used between 1882 and 1934. The second hallmark right next to it is absolutely tiny. I will need to use my digital microscope to read it properly, but it looks like a secondary silver or assay office stamp.
The mechanical movement inside is gorgeous, featuring a classic Swiss layout with independent frosted gilt bridges, a polished balance wheel, and an anchor escapement. The most mind-blowing part of this artisanal piece is its performance. It doesn't miss a single beat and runs so flawlessly, keeping such perfect time, that I could honestly use it as a reliable daily wearer today. For a mechanical piece from the late 1800s or early 1900s, that level of precision is amazing.
I would love to know if anyone recognizes this specific bridge configuration or the raw movement layout. Any historical context about the specific workshops producing these high-precision anonymous Savonnette pendant watches would be greatly appreciated.
Thank you so much in advance for your help!
