dear all please could you identify the watches below and give me the ref please? thanks for you kind assistance credit (as written on the pic) ...  

here is the pic ...  

can you get the source who took the photo to get you more information? Bill

Interesting pair of watches from about the same year. 1955 or thereabouts, both with the movement 453. The one on the left looks to be a "Jubilee" model which had a reference number of 4600. If so, there would be an inscription on the outside of the back ... 

The one on the left is very original, Dial, hands and crown are as it left the factory. Polished but very nice looking. The one on the right has replacement hands and crown. They would have been the same as the Jubilee.

which inscription please?
