Elgin Grade 466

The grade 466 is a 16 size movement, with 17 jewels.  There's nice gold jewel bezels and a micro-regulator.   It is a lever-set movement.

This example in an engraved, base metal, open-face case, was made about 1921.  The heavy hands and larger Arabic numerals were popular at that time for giving a watch a "professional" look.
