I’ve looked for identifying marks but can’t find any. I didn’t remove the dial to look as I would prefer to not take it apart. The case measures 32mm and is sterling silver. I’ve done a google search and couldn’t find any Other examples this early other than a Patek Philippe, Breguet and Audemars Piguet.

Any help would be greatly appreciated.

Without being able to contribute to the actual question, I really love the design of this watch, case and dial.

Cheers, Bernhard

The FG in that shape, could be Picard? Picard & Cie. / Fabrique Germinal
It could also be Lorenz Gebr. Furtwängler / Uhrenfabrik vormals Lorenz Furtwängler & Söhne
It looks to be similar to an early AM movement? From A Michel. AM, A. Michel SA, Grenchen.
From David Boettcher's site
If the dial ever comes off, the symbol shown below may be stamped on the dial side of the movement.

The Lorenz Furtwangler & Sonne monogram looks similar. I’m not sure. Or perhaps his son Georges Furtwangler?

The GF monogram looks very similar to georges furtwangler ( which I guess is the son of lorenz furtwangler ) but a google search doesn’t show very much at all about him, let alone wristwatches by him.

I should mention as well the calendar does fully function, it’s not just for “show”.

I did find this movement which is very close by General Watch Co. or “Société d'Horlogerie La Générale”, which I guess the Brandt brothers comptoir business ‘Brandt fils’ was changed to, which eventually became the Omega Watch Company.
