Greetings. I picked this up at a street stall in Saigon a few days ago. A quick look at the face and movement led me to believe that it was a reasonably authentic hand-wind, maybe from the 70s. After some haggling, I got it for US$35.00. I like the feel and look of it, especially the red second hand and it keeps great time. Upon opening it, I saw that the case is marked Waltham Watch Co. Hong Kong Case. Have the more experienced among you out there seen this before? Thanks!
