That looks a lot like my grandma’s watch. Don’t take it the wrong way, she was quite a woman! One of the first women in France to have a driving licence («*permis de conduire des voitures à pétrole «*), she married my grandpa just before he went to war (WW1) and became a supervisor in a telephone exchange (at a time when it was unusual for women to have a job). Her watch was one she used professionally (not just to be on time, to check if others were). Not a Roamer but looked almost identical otherwise, to the bracelet.
