she isn't pretty but I am 99% sure this is a real rolex Oyster Speedking, I will know more tommarow when I take it to a watch shop. I hope I am not speaking to soon because I cant get the back off. But thru all the research and running the serial # through the web site which said it was made in 1945 and all the signs and markings I can see I think it is real. The numbers on the dail are painted with iradium which has bubbled and turn black. I was hunting a house from 1939 found it around 5 inches or so the time frame is right and I dont think they made to many stainless steel knock offs back then. keeping my fingers crossed. HH to all I will update when I find out.
