1940s Ladies Rolex 4323

[RagsRiches]

Hi... I am new to this forum and I am looking to buy my first Rolex which is a vintage ladies 4323 model.

I am told by the seller that he cannot find any serial numbers on the watch and it is possible that for this series of watches they were no serial numbers. The watch is from the 1940s. The watch looks legit to me. I would be grateful for any advice to guide me on this. I was able to upload only one photo unfortunately.

Thanks in advance.
