waltham watch serial number lookup pocket

I decided that since both are similar movements and the same size I would weigh them. I have had two different jewlers look at the case and neither can determine exactly what it is made from without an acid test, which I will not let them do. It too has a Waltham movement, serial 3439715. One of them is the one with just Waltham on the case with a serial and no other markings. Recently my wife's mom passed and we inherited the watches that she had. When I was 12 my mother passed the watch to me so I have had it for 50 years. My mother asked her grandmother if she could have it because it was so pretty. He offered to buy the watch as it was not working.

She raised my mother and one day a scrap gold dealer came to the door. My Waltham 14K case with with a Waltham movement serial 4154394 belonged to my great grandmother. I have poked around the site and all I can say is wow, what a goldmine of information. I would not be here except for finding this site based on this thread. If the case doesn't contain the words 'Warranted US Assay 14K (or 18K)' I assume it's not gold until an expert tells me otherwise, or until I've had it tested. There is another book referred to as 'Ehrhardt's Trade Marks' which I believe is rather better, but I have been looking for a copy for two years without success. I have a book called 'History of the American Watch Case' by Warren Niebling which contains some trademarks, but the book is far from a complete reference (it doesn't even mention Waltham Watch Case Co !!!) and it says nothing about karatage marks, and it's pretty difficult to use for reference. My practice has been to check specific marks here, and then slowly to learn which marks mean what!

So presumably that applies to yours tooĪmerican 'hallmarks' are problematic because there was no legally enforced marking system. My second photo shows the 'Waltham' mark only, and I have been assured by knowledgeable people here that this is a 10K solid gold case. If there is an accompanying mark (as shown on my first photo below) this would show that the case is 14K solid gold. The trademark in your photo is one of the correct marks for the Waltham Watch Case Co.
