To add to the good information posted by the others:
Please excuse me if I repeat some of what you already know, it's easier for me this way. Checking the references listed in the Hampden Watch Co.
Encyclopedia article (and looking at your pictures), Hampden movement serial number 3,320,440 can be seen to be
Wm McKinley grade
Adjusted to Temperature and three positions
(to be confirmed),
having 17 jewels
and a Starwheel Patent Regulator
The movement is fitted with a single-sunk, Roman dial
having a R5MT (Red 5 Minute Track).
It was built in about 1915, give or take a year or so.
You can see a brief catalog description of the 17-jewel Wm McKinley grade, along with a picture and where it fits in Hampden's line of model 5 16-size movements, on page 6 of the 1926 Otto Young & Co.
Jewelry Catalog, shown below.
Your Watch Case
and was made by the Illinois Watch Case Co.
Unless you know that it has been properly cleaned and oiled within the last few years, you should have the watch serviced before running it very much. It may be helpful for you to read the Encyclopedia article on Watch Service
and its related links, especially the one to the message board thread on the subject
. The Encyclopedia article on Choosing a Pocket Watch Repair Person
may be useful as well.
Having gathered and printed out information about a family watch, it is a wise idea to write out as much as you know about the family member to whom the watch originally belonged - or as far back as you can go, including (and clearly identifying) what you can guess. Then, add the names and relationships of the family members who passed it down to the current holder. Make up a booklet with this and all of the watch information and try to keep it with the watch. You might even include a CD or, better yet, a USB thumb drive with copies of the pictures or information, in addition to the printouts. Even though they may not be readable 100 years from now, some more recent descendent may transfer the files to the then current format and media. This way, the watch has real family heritage instead of it just being an old family watch, the identity and relationship of the original owner having been lost in the distant past.
