How do I identify a Waltham watch?
Open the back cover of the watch with your fingernail and look for identifying names -- a magnifying glass or loupe may be necessary. A Waltham pocket watch will have A.W.W. Co. and Waltham, Mass. on the movement, which is the inner workings of the pocket watch. This will also include the grade of the watch.
Where do you find the serial number on a Waltham pocket watch?
All Waltham pocket watches have a serial number stamped on the movement (the works) inside the watch. The serial number can be checked against an online Waltham pocket watch list, which will give the approximate year of manufacture. Waltham pocket watch serial numbers can be accessed by opening the case back.
