Hi there, Yesterday my mother called me saying she found an old watch and asked me if I wanted it. When she sent me some photos, I was quite surprised to see a Paul Ditisheim. I know his legacy, but I don’t know much about his watches. Could you please help me identify the model and maybe some history behind it? The photos are not the best and I won’t ask my mother to open it to show me the movement, so here’s a transcription of all information engraved on its case you can't read it from the pictures: Face Paul Ditisheim Fabricant La Chaux de Fonds Front Grand Prix Paris 1900 Paul Ditisheim Maker to the U.S. Navy 74 Prix de L’Etat Premier Aux Concours Chronomètriques Des Observatoires de Kew Washington & Neuchatel Back (A crown icon) 3-17750y MF 0 (upside down) Grand Prix DITIS Paris 1900 18K 0,750 27744 You can see the watch is not on its best condition. Do you think I should send it to repair? Thank you!
