How find serial number on ~1910 hamilton pocket watch?

The serial number is usually engraved on the movement. If you open the back of the watch, you should be able to see it.

I looked at the Hamilton pocket watch site (in might be helpful if you visit the site, simply type "hamiltonpocketwatches.com" into your search engine and your will be able to examine photos of a number of movements).

The position and size of the number varies but it shouldn't take to long to find. One of the pictures I found impossible to see the number but the rest I found, although sometimes you had to look quite carefully.

What is the true value of the pocket watch?
