Rolex 6605 (from 1957,Q2)

My quest to complete my collection of the Pre Datejust continue with this Rolex ref 6605 from the year 1957, Q2. Basing on the model number, the Rolex 6605 was only produced from 1956-1959 before it was being replaced by the  ref 1600,1601,1603. This is one of the classic Pre Modern Datejust, which has the overall look and feel of the Datejust . The Rolex 6605 has a few variations namely with White gold or yellow gold bezel, in Engine Turned bezel or flute bezel, and using either the A.296 or Cal 1065 or 1066 movement, sword shaped hands or rectangular hands etc.

Lately, I am slowly letting go some watches as the quantities have become unmanageable. I have started to clear away those whom I think JJ would not like..
