I have had this movement for some time, and think it is a beautiful piece. As you can see, it is a hunting movement, very thin, about 12s. I don't know what my chances are of ever finding a case that will fit. Can anyone tell me what it is?

Here is the dial:

and the movement:

My guess would be Swiss. The A & R on the balance cock for Advance and Retard and no name or numbers are very common.

Yes, and maybe made for the English or American market, since it also has an F and S on the balance cock. Thanks for the insight!

It seems funny that so many very high grade swiss watches have no markings whatsoever. What do you suppose the logic was behind putting so much into a watch and leaving the name off?

There were so many poor quality swiss fake movements shipped to the US that I think there might have been a guilt by association mentality. Therefore, no name, no association. If you grew up in the 1960's you would look upon anything from Japan as Junk, but we all know how that turned out.

Yes, but they were required to stamp "swiss" on the movement at some point, weren't they? I think it became a law for importers.

Lindell's suggestion of pulling the dial is a good one if you want to go further. I have found Swiss markings under dials, on the back of dials, stamped along the edge of the movement and buried in a number of places. I'm pretty sure at some point the country of origin was required to be displayed, but I don't know when that was. I have seen Swiss fakes that are just awful and are a waste of the material they are made from. I have also seen Swiss fakes that are very well made.

This doesn't seem to be any more or less than what it is, at least. There are no misleading names or expressions on the movement or dial--nothing at all, in fact. It does have a nice compansated balance. I will ask my watchmaker to take the dial off and look it over.
