I've never seen that dial or that blue color. If you look at the markers some touch the minute tick mark, some don't...so yeah, mot sure what this is!

A Reverso of which era?

I think the disk is ok, but these are readily available, so it's impossible to tell if it actually came with the watch.

The case reference number might be stamped on the insides. It most likely does not have a model name. Value is probably around $900.

The /1 /2 and so on indicates the first evolution second evolution, etc. of the movement. These differences can be very subtle.

It looks like one of the many generic Swiss nameplates that existed during that era. It's not an issue military piece, but a civilian watch of pretty low value.

Is this a watch bought in the U.K. maybe?

Gold filled watches back then sold around $60-75.

It it's running it's worth around $400...

I can only date via the movement serial number but it will be around 1968.
