I would like to get some information about the pocket watch that used to belong to my grandfather. It's an AeroWatch with the text AeroWatch, Neuchâtel and Swiss Made on the dial. On the back of the watch there is text AeroWatch Neuchâtel, Base Metal, Swiss Made, 1003.
What I would like to know is that what is the model, age, movement of this pocket watch plus any other information you would have about this watch or AeroWatch in general.
Here are some pictures of the watch. Incase the serial number(?) is not visible in the last picture, the numbers are 6431 6445
edit - numbers on the movement corrected -
