This is an Unbranded Silver Plated Trench we believe this was produced around 1918, we cannot be certain that this watch saw active service. Its is in pretty good condition. 
 
The case is Silver plated and shows little signs of wear, the enamel dial shows a small crack below the 6 mark other than that it's in excellent overall condition 
Inside the case is a 15 Jewel Swiss Made movement. We have recently serviced this watch and replaced its Balance Staff & Spring. 
 
Cosmetically overall this is in good condition for a watch of this age.
