can any one help to identify this watch?

There are no markings on the movement. The dust cover is marked 0.585 and also has a circle with a stylizes b and another circle with a fancy crown in it (does not look like uk crown) and a serial number 75451. The dust cover is not marked. There is a small mark on the bow but I can not read it with a loop.

Thank you

The crown might be the German assay mark for gold; I can't make out the B in a circle, but it could be a casemaker's mark and if I could see it clearly I might be able to find it on the Mikrolisk site. I would be satisfied that this is 14K gold based on the .585 marking.

The movement is unusual - I have never seen that sinuous S-shaped centre bar, and the swan's neck regulator is a sign of good quality - the adjusting screw is unusually long! Unfortunately I can't help with an identification.

I found this on Mikrolisk - is it anything like yours?

I will have to recheck but I am pretty positive that is it. Thanks Marty! In the fourth picture the mark is upside down on the right. So that would make the case:
BIFORA Uhren GmbH, JosefBidlingmaier Schwäbisch Gmünd, Deutschland

Would the movement then be German or did in Germany the movements mainly come from Switzerland?
