Hi all,

I'm new on this Rolex forum. My wife has an OP ref. 1002 and I don"t know what is the production year . The serial nr. is 1187xxx. Looking at " Bobswatches" site the production year is 1964, at "Bernard watch" site is 1959. The movement is a 1570 caliber, which was introduced in 1965 as I know. What is the truth ?
Thank you for your help.
