Yes, in 30 years !Vintage?
Yes, you told me that before! As they say, "Cool story bro! Tell it again!"Very nice!
Did you know that you are wearing a Waltham watch?
Waltham had declared bankruptcy in 1949 and continued to sell existing stock until 1958 when all remaining inventory went to a company called Hallmark. In line with restructuring efforts, they had opened offices in New York and imported watch movements from Switzerland. The main creditor of Waltham did not allow the use of the Waltham name on the watches, so they sold them under the name Hallmark. Waltham is still around through Waltham Switzerland, founded already in 1954.
It would be nice to see the movement and the US import code. But if you open the watch, which is very easy to do with a two-shell case (just watch out, sometimes there are hinges on one side), there is the danger that the movement falls out immediately. Also when looking at it or taking images, you have to be careful, make sure it is supported well on the dial side in order not to bend the hands.
Whatever, perhaps you are tempted to say that you have already serviced watches before my parents were born ...
