The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement is fully signed and the serial number 26,399,583 dates it back to 1927.

The grade was named after Patten Sargeant Bartlett who was one of the early employees of the Boston Watch Company which went on to become the Waltham Watch Company. He subsequently left Waltham to work for the National Watch Company at Elgin Illinois but eventually returned to Waltham to work as a salesman before opening his own wholesale business.

The watch measures 50mm diameter excluding the winding crown and the loop. The case is silver and there are hallmarks inside the two case backs for Birmingham 1918. The difference in dates suggests that the original movement was replaced as a more economical alternative to a repair.

The case is in good condition and has engine turned detail to the back along with a central cartouch which contains the initials GEP.
The watch glass is in good condition, as is the signed dial with blued steel hands, a subsidiary seconds dial and an outer minute track.

The watch comes with a single silver chain, 41cm long including the T-bar and the clasp. The chain is hallmarked for 1916. Each of the links on the chain has the lion passant silver mark. The chain weighs 31g.
The watch and chain will be sent in a new presentation box.
