Hello everyone. Are you looking for a DateJust but looking for something a bit more unique than the ever-present 1601? Then, this might be the watch for you. Up for sale or trade is a very rare Circa 1958 Rolex DateJust 6604.The DateJust began its life in 1945 with the introduction of ref. 6305. This watch featured Rolexs cal. A.295 (and later the upgraded A.296) was manufactured between 1945 and 1956. Next in line came the improved cal. 1065 and with it the DateJust 6604 and 6605. This reference number was manufactured for only three years between 1956 and 1956, at which point it was replaced by the considerably more common 160x series with the 1565/1575 movement.Given the short time frame that the 6604 was made, it is hard to argue that this reference number is among he most rare DateJust models. This particular one features a smooth gold bezel outlining the traditional 36mm case together with an original dial, hands, and date disk. It is currently paired with an aftermarket oyster bracelet. Inside, as expected, the watch has a clean cal. 1065 movement that is beating well and keeping accurate time. Overall, the watch is in great vintage condition and is ready to be enjoyed by the new owner.
