NW RAilaoad watch

I have a watch that was my grandfathers from the NW railroad back in the 70s
And i cannot find any information on it. It looks like: there are no numbers, there is railroad tracks around the watch where the numbers should be and a train goes around the watch when you wind it up, it is sterlan silver. it does not have a name on who made the watch, and on the back it just says strelan silver .
I was wondering if any body new anything about the watch.[^]

[#welcome] Don’t know, but you should post that over in the prototype area as well.

And if you do, it should be “stirling” silver.
