BOSTON WATCH CO. 11 Jewel, Hunter, made by Hampden in 1882. 

Dial & Movement both marked Boston, Watch Co. 

Movement is a Model 2, 11 Jewel, Nickel Finish, w/ Plain Regulator, made by Hampden in 1882. [ The original Boston Watch Co. only made 5000 watches & went belly-up in 1857. The first Hampden Serial No. marked Boston Watch Co. that I could find, was a Key Wind, Gilt Finish, 18s, 15J, Adjusted Model, made in 1878 ].

The Case is a 18 Size, Gold Filled Crescent Watch Case Co., Case w/ a Stag's Head Engraved on the Front Cover. 

Rear Cover is an engraved Village Scene. This case seems to be original to this movement [ no extra screw marks ] of course without the original Jewelers Invoice no one can be 100% certain.

Crescent didn't mark most of it's cases with Karat numbers or Wear Guarantees but this Trade Mark was used to indicate a Gold Filled, 14K, 20 yr., Case.
