Looks like a Longines Conquest. In superb NOS condition it seems…

… considering the so clear markings you show in your picture.
Small as per present modern trend to big watches it is a beautiful watch and a pleasure on the wrist.
Mine is far to be in the superb condition of this example here but I enjoy wearing it from time to time.
If you like classic vintage watches go for it!
