This is a Gents Vulcain Watch from around we think 1938/9. 
The case is Nickel Silver Plate, the dial shows plenty of wear, however the numerals are still readable and clear, the Vulcain logo has faded. On the back is a military presentation engraving to L/Sgt A.Wadsworth from the 1st Middlesex Regiment. 
Inside the case is a 15 Jewel lever movement signed Vulcain


Cosmetically this has seen wear and tear, however it has plenty of vibe, looks great on the wrist and works well.
