Watchmakers are excellent people and great caretakers of their time pieces. Here are some specifics about this pocket watch case. Model: 3/0 Open Face 25 year gold filled case. Case Composition: Dueber 25 year gold filled. Case size (measurements not including bow or crown): 32.5mm in diameter. Notes/Condition: As you can tell this is a very clean pocket watch case. 3/0 is the perfect size for a lady to wear on a necklace. The service history of this watch is unknown to me unless I state otherwise. Therefore you should expect to service this watch if you are a responsible collector. Often times these watches have been forgotten in a jewelers desk or in a back room for 30 plus years. I like to save them from that demise and get them back into the hands of collectors. It doesn’t take very long for old gummy oil to stop a movement from running (many times just a week or so) or even worse if the oil is dried out it might not take too long for the watch to grind itself up inside so please understand I can only tell you how the watch is performing here. Please take a look at all the other clocks and watches I have this week and weeks to come as well as my store inventory. Please feel free to ask questions or request additional pictures. Because of this I package items better than necessary to insure a positive experience.
