Asking $2450 shipped US Up for sale is a 6284 Semi-Bubbleback. The dial and hands have aged nicely and the dial has a yellow/orange patina. The case is in good shape and still shows some original finish on the lugs. The head measures about 34mm in diameter without crown. Under the 5' o clock lugs, it appears that someone's initials are engraved. The bracelet with the head should fit a 7 inch wrist. The watch runs ok but has not been serviced in my possession - I recommend a service. If you have any questions, feel free to send a pm!
