The grade 13 is an older 18 size, 11 jewel Elgin movement.
It is key-wind and key-set movement, note the square hub in the center of the hands. The same size key sets the time, directly at the hands, as winds the watch.
This one, in a nice silver, triple-hinged, case, was made about 1882.

I own and enjoy a grade 13 in a keystone nickel trip hinge case. Love this watch:-)
Nice watch!
