Anyone know much about vintage Rolex pre 1930

[Nazar]

Hi guys
I hv just inherited what I think is a pre 1930s Rolex. There are no distinct markings in the movement to determine a model number...neither can I see and markings elsewhere.
I hv tried to upload pics but it isn’t allowing me to do so..

I will keep trying but just thought someone might know what exactly I should b looking for... it has a round dial with a golden colour and the second hand has a seperate dial at 6 o’clock, which was common in Rolex watches pre 1930..the difference with this is that it has a two tone dial..

Please could you advise what would help me identify this Rolex and what it’s value might be.

Thanks
