1918 Buren Sterling Silver Gents Military Trench Watch 
 
The case is Sterling Silver Hallmarked London 1918, and is in very good condition, the dial shows some signs of wear but for a 100 plus year old Trench watch not bad at all, it may very well have seen action ( nobody knows ) .
The movement is a 15 Jewel Swiss Lever Movement signed Buren. 
 
Cosmetically overall this is in very good condition and running well.
