I’m selling a nice vintage 16 size, 21 jewel E. Howard (Keystone) Series 10 pocket watch. The pocket watch has been cleaned and timed. The watch has a nice double sunk dial with some small chips at 2, 3 and 4 o’clock. The watch is housed in an original E. Howard yellow gold-filled case. Based on the serial number, this watch was made circa 1911.
