I have been given this 1950's vintage (I think) Bucherer Day Date Automatic. I could only find one picture of a similar watch with the day and date arranged the way this one is in my internet searches. It is missing the crown. I was wondering if anyone could tell me the model number and the value for this particular watch. I have a local watch guy that is pretty good with repairs so I was wondering if it is worth fixing. Thanks for your help!
