1923 Omega Cockpit or Dashboard Clock?

Hi,

Any help would be appreciated on what I think is a 1923 Omega that I've inherited. It's a big old thing at 71mm wide. It works well. I found a few similar ones on the web earlier in the year but have lost my notes and can't find similar ones again. I'm trying to find out any details about it.

I think it could have a 59-8D calibre movement but they seem to have second dials, so I'm happy to be corrected.

Has anyone any ideas on what it was originally designed for (cockpit, dashboard, other?) There is a loose ring around it (see red arrow). The front and back of case both screw off.

Any clues for its value and/or best place to sell it as I'm unlikely to keep it.

Thanks

Help please.

It's a car clock. Serial number is from the 1920s. The hands could be wrong; not sure.

These are fun collectibles, but not rare, nor particularly valuable. Around $100, I'd say.

You are right about the caliber, if you look under the balance with
a loupe it can be confirmed. Due to the lack of sub second this
is a dashboard clock, and they usually are with sub second too.
I have collected a couple of these, and I have paid in 350-500$
range. 100$ would be a steal IMO
