Found this the other day.
Have done some research and the WWW on the back predates the internet.
Apparently it is Wrist Watch Waterproof and is an early issue watch?
It has the crows foot with a serial number.
It was probably a German soldiers souvinere.
It works intermitantley so I suppose it needs a service. I don't know if people still do that?
I don't know what sort of strap it would have had, leather I suppose?
Any one any other info?
