Some watches open with a hinge near the six o’clock position.
Often there is a raised lip opposite the hinge that you can pry open with a finger nail or pocket knife. Here you have two hinged covers: one for the front and one for the back of the watch.
These are generally the easiest as for many makes, such as Waltham and Hamilton, production records are still extant and enthusiasts in the US have put a huge amount of effort into putting them into online databases so by taking the serial number of the movement (not the case number!
) and entering it you can get the production date usually to within a year or possibly two but sometimes to within a month.
The depressed crown will release a latch that opens the front cover over the crystal.

This information can be used to find the year that the watch was made.The manufacturer’s name may be very simple to find, or it may require some deeper investigation.If the major components of the watch (the dial, the case, and the inner workings) were all made by one company, you should find the same name marked in all three places. However, in many instances these three locations may each be marked with a different name.Today, Waltham watches remain highly desirable collectible timepieces.
