The Rolex Datejust is now a ‘poster boy’ for Rolex, globally recognisable and one of the most popular and timeless watches in the world. Prized for its versatility, accuracy and elegant design.


This example is a reference 6605 from 1959, with a tropicalised silver dial with standout ‘arrow’ hour markers and stepped pie-pan dial edge. It has a date window at 3 O’clock, with black Arabic date signing. The hands are of luminous Dauphine style, with ties in neatly with the arrow markers. The dial is protected by the original acrylic crystal with date magnifier.

The bezel has an unusual engine turned finish, which is rare to see on this model. This distinctive bezel is mounted on the 36mm Stainless Steel Oyster case which has clear signs of ageing. To the right is the screw down Oyster crown with Rolex Cornet logo.

The screwback Oyster case is signed with the reference 6605 to the inside, with the date code II.59 which dates the watch to the second quarter of 1959.

The beautiful Rolex 1605 movement is inside, with the aesthetically pleasing butterfly rotor. It has been recently serviced and is keeping time to within COSC standards.


In 1956, Rolex introduced two new Datejust models, the 6604 and 6605. The 6604 had a smooth bezel, with the 6605 having a fluted bezel. The 6605 also came with an engine turned bezel which sets this example of the 6605 apart from the other Datejusts of the same period.


These were the first datejust models to have the now classic tapered profile, with the more conventional flat profile to the rear. This example has a dial which blends the design of the 1945 Rolex 4467 & 5030 from the early 50s, with that of the 1960s 160X examples with the 1560 movement.


The 6605 is a model which is more readily available than its two predecessors, but still isn’t commonly seen due to its 3-year production run between 56 and 59.
