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
a 16-
size,
model 5,
Wm McKinley
grade,
Adjusted to Temperature and three positions,
pendant-set (to be confirmed),
open-face movement,
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 is
gold-filled 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.
Unfortunately, many of the links in our Encyclopedia articles were disrupted when we changed to the current version of our Message Board and its been a long process getting them all reinstated. So, if you come across a broken link, please report it

Please feel free to ask about anything that isn't clear to you.
Good luck,
