This is a lovely Vintage Bucherer  Watch. It has 10 microns of gold on it, which means it has a decent amount of gold, and it shows no wear on the metal. It is in nice pre-owned condition, very light wear consistent with normal use.  It is 6-1/4" closed, but it will open up to approx. 7"..  What a great addition to any collection!  Dial is very nice, tiny amount of dust. I cannot guarantee the accuracy of vintage watches, but this one appear to just need servicing.
