UPDATED INFORMATION INCLUDED - For the 3rd time!
This was an eBay rescue that I am trying to learn more about. Since someone has added rubies to the dial, I believe it may have been modified, perhaps extensively.
I am not a watch repair person, so I was very hesitant to dismantle the watch. I gave it a shot, and I have included photos of the movement and case interior. In addition to the "official" stampings on the part that holds the movement, it appears people have engraved other information into the case over the years.
The exterior case dimensions are 38mm (lug to lug), 32mm (w/o lugs) and 25mm wide.
I had previously believed there was no ID number on the back. I am a dolt. It was there all along and is shown above.
Based on the information on this website, it appears to be a 1943 model.
Thank you for your assistance.

Very interesting case. Sterling base? If they are referring to a sterling silver base metal with rolled gold on top, this is a rather kick ass Vermeil. Normally Vermeil is Sterling Silver with gold electroplate.
Lots of service, marks, usually a good sign, but that gouge on the bridge is worrisome. Possibly a re-dial in addition to the 'rubies'. It looks to be in very good condition, with no case wear marks, which always makes me look much closer.
Commodore matches the ad for the 42 in db.
1943 Commodore. Non-conforming or modded dial, as noted.
