I wonder whether anyone can help me with identification of this movement? The watch and movement appears to be unsigned. Swiss case marks for 0,800 silver (Grouse). It is shortly going off for some attention from a watchmaker as it has a problem with the flyback chronograph not resetting. I have had the watch for a long time. I have a dim recollection it might be by Doxa? The numbers near the balance are 322 598.
