This is because this watch has been RE CASED and is not the original. Other than that the watch is completely original. The dial and hands are original as well as every aspect of the movement. I've gone to several jewelers and have done my research and discovered this watch is one of the rarest watches the world has to offer.
It uses the correct Valjoux 55 movement and is properly signed Rolex on the movement as seen in the pictures. Additionally I had a watchmaker remove the movement to find it is also signed Rolex on the base plate. The chronograph feature works perfectly. There is a lot more to be said about this piece of art. What you see is what you get, message me with question!45mm across not including crown. One other note, the watch is old, a small hand full of times when setting the time the stem and crown has pulled out completely.
I was able to fix this myself by just tightening the adjustment release screw for the crown and being carful.
