Please help with this art deco ladies Bulova watch!

My 93 yo neighbor gave it to me, can't remember too much about it. Bulova support has no vintage records from the era. MyBulova doesn't have it in their catalog. Reverse image search found nothing. Reddit threads have come up empty. Watchophilia either. But the design is very similar to others from the period.

I'm starting to believe I can't find any info because it's not legitimate, based on some info from watchophilia.
1- no marking on the case. The only marking is Kreisler USA on the band. From research I do believe the two companies did have a supply relationship, though.
2- the shape of the border around the numbers does not match the shape of the case. Square border on case with rounded sides.
3- we're in NYC, Bulova homeland, so perhaps there was a market saturated with counterfiets at the time.

Do you think the lack of marking is just due to practices at the time?
If you believe it's not legitimate, do you still think it's worth cleaning and repairing? I think she's so pretty.
Any idea what you think the metal used is? I can't tell if the green are true stones or glass.

Thanks either way, it's cool to see everyone's watches here! If you happen to know any vintage Bulova enthusiasts who wouldn't mind their contact info shared, I will gladly reach out to them! Thanks and be well 😁

I think this may be the 'RITA' model, shown here in 1928 adverts.
Edit- although as Gator says, the movement and dial have probably been replaced. Very nice.
