Rare Rolex Datejust ref 6605 Black Gilt Dial with 'OFFICIAL TEST' Text

SCBOT text for rare testing lines…

We are delighted to be offering a rare and stunning yellow gold Datejust. The watch has a dial version that we have never seen before on a Datejust (possible unique) and features the chronometer text: “SUPERLATIVE CHRONOMETER BY OFFICIAL TEST”. The Reference 6605 saw to introduction of the new 1065 movement, which suggests this exact watch is a prototype model to test the new movement. 

The dial is gilt, in great condition and featuring unusual heart-shaped hour markers and a gold frame around the date window.
The watch has the additional nice touch of still having the original yellow gold BREVET winding crown that features the prominent ‘+’. This is arguably one of the most collectible and rare Datejusts that we have offered and would be a super addition to any watch collection! The watch has been fully serviced by our watchmaker and will come on a Bulang and Sons leather strap.
