Lovely WW1 Watch, 1917 Officers Sterling Silver Trench Watch. 
 
The case is in very good condition for its age Sterling Silver and Has a Glasgow Hallmark for 1917. The dial shows amazingly little signs of wear for a watch thats over a 100 years old. 
Inside the case is a AS 137 Calibre Jewel Swiss Movement 
 
Cosmetically Overall this is in very good condition for its age and is running well
