Bulova 1958 International

Hello, this is my little Bulova square watch. Would you be able to identify the type of this watch, please? Moreover I am in search for a new crystal because mine is broken and perhaps your information can help me. I would be very happy to find a new glass or at least a G-S number to order a new one. I don't want to give up the hope to manage to get hold of a new glass. It is 25.0x25.0mm sqare, flat top, round corners, high edges.

Many thanks and best regards, Tom
