Something like Junghans should work.

It looks like maybe a French made case from the 1950s?

For a collector the dial refinish hurts the value, but maybe not so much for a more casual person that just wants a nice watch. I'd say in my circles it's worth around $1000 - $1400.

Movement made around 1971 though it may have been cased a little later. It has an adjusted to 5 positions movement indicative of chronometer grade, which is nice.

It can't possibly start with a "4", so assuming it is a "1", the watch dates to 1961-62.

Try again please, that is much too high.

Original dials on these watches are never that good and most of these cal 4xx snap backs have had their dials redone. The small details that are 'off' are a good indicator of the dil being refinished. I'm certain it's been refinished. I also see the print of the sub second area being slightly too hi...

They seem OK, but the pics are low resolution.

Maybe $450-600. It's not all that collectible and the Valjoux 7733 isn't one of my favorites.

I think Wakmann was the US distributor, and Gigandet was the Swiss brand.
