Does anyone recongize this Rolex model?

[scobiie]

The watch did not come with original case, when I bought it was in a case provided by the seller. I've took this watch to a professional, for more details about this watch. With great interest, he examined the watch. The watch uses a mainspring. The case of the watch and the dials are all in gold, 18K. Below the 6'o clock dial there are the letters "SWISS" On top are the words "Orchid" and the 12'o clock dial is the Rolex crown symbol. Under that writes "ROLEX"
and on the back under through reflection the crown symbol could be seen, at the very bottom, there are the 6 digit serial number starting with 321XXX.
He told me the parts in this watch dates back to around the 1930s. And the watchband is presumably replaced at the later date, which the original uses leather.

However he still can't determine which model it is =(

Thanks to all =D

Serial # dates to mid '40s. Currently Orchid is part of Cellini collection. You can have it assessed at an RSC for about $150.
