The silver hallmark is for the Russian market. The retailer was already mentioned by Jim. As for the movement, maybe this could help, considering the period: http://omegaforums.net/threads/ww1-omega-trench-watch-help.16383/#post-179046 What strikes me though, is the beautiful and excellent preserved Roman numeraled dial w/ no seconds and of course the 9 o'clock crown. Maybe specially made for a right hand wearer ?
