Hi Brian,
nice watch! I can only provide you with the catalog ID, I have never seen this watch been advertised. So all I can tell you is "Strap 393", date of manufacture approximately 1940 (plus minus one year) and that the movement is a Swiss Gruen made caliber 401C.

Barney, do you know, are these style of hands luminous? If so, would that mean radium?

The hands originally would have had radium containing luminescent material.
Thanks, Jack. Was radium used in the paint for the indexes? My tuxedo dial has something akin to a champleve design, though I don't know it to be enamel, so that may not be an appropriate term.

I disagree with Jack, in my opinion most likely the hands were not Radium filled. Here a closeup of another watch with these hands, looks like the slotted hands were not filled at all:

There is one easy way to find out. Shine a UV light on it. Florescence without retaining glow is a good sign of Radium. If no florescence than likely no lumed material.

Yes, I think you are correct. For contrast.
Someone posted another Gruen model with this style hand on one of the FaceBook groups in the last week or so. I asked for their assessment, but did not get a response.
