WW1 1916 Sterling Silver Mid Size Unusual Trench Watch 
 
This watch has a very unusual dial, the case is Sterling Silver was assayed by the importer George Stockwell and has a London hallmark for 1916. It's the dial that stands out from most of the other watches of the time and frankly we've never seen a guilloche dial in this time period before, so it's different. It's a blue/silver guilloche dial it looks period as well, so it's pretty different, there is a small hairline crack on the dial between the 10 and 12. 
Inside the case is an unbranded Swiss Movement
 
Cosmetically overall this is in very good condition and running well.
