... little watch.
Yes, it is from the 1960´s, circa 1964 to be more precise.
It is a reference 9659 which was referred on the Rolex catalogs of as the "Elegant Watch" model.
It has a manual wind movement caliber 1210 with 17 jewels. Case is 18K gold with pressed back (not water proof).
Yes, Rolex made manual wind movement watches, as well as watches which were not "Oyster" cased, so not waterproof. Even in later years Rolex kept offering these manual movements.
I have in my collection other examples, with an Oyster case, threaded winding crown, but with original manual movement. They are very nice watches, case with the classic Oyster shape, but a bit thinner than the automatic counterparts.
Thank you again and have a nice week end! Best cordial regards, Abel
