Sorry, the answer is probably not. As a rule of thumb most WW1 trench watches were a round case (mainly silver or nickel) with a white or black dial and poire squelette hands or some form of dial and hands that could be lumed with radium etc. During WW2 watches were more robust and more like watches we see today.
A nice watch all the same.
You will find a huge number of people selling watches on the internet that state 'WW1 officers watch' when the assay mark reveals that it is from the 1930's. In all cases when you are looking at trench watches take this to heart 'BUYER BEWARE'
I have made some costly mistakes buying watches and watch parts that are supposed to be one thing and turn out to be another. My view now is that if the watch can put a smile on your face then it is worth every penny.
