Friend of the show Boris Pjanic who deals in watches and occasionally writes about them too, found this bi-color Rolex Datejust reference 6605 with German writing on the dial for the indication of the chronometer movement.

Boris writes us the following:

Collecting and trading watches for over 16 years has enabled me to pursue my love and passion for vintage watches which was instilled deep inside of me as a child.  What I recall is that as a child I used to look at the windows of jewelers in town when my parents too me for a stroll.  While I am not coming from a family of jewelers, nor do I possess any other relation to the business, I have always been wanting nice watches.  Not necessarily from a specific brand, although Rolex was always on my mind.

Combining passion for a hobby with the pursuit of creating a business from this passion has widened my reach, and I have met many interesting people and even more interesting watches.

Watches-and-art-002 sNow I have found a quite rare piece, a Rolex Datejust from the late 1950s, reference 6605, in steel and gold, which has one very fine distinction from all the other Datejusts 6605s.

Watches-and-art-007  6605The writing on the dial for the COSC is in German and says: “Superlativer Chronometer nach amtlicher Prüfung” instead of the regular English writing: ” Superlative Chronometer Officially Certified”.

So far, I have found one watch with the German writing which was auctioned at Antiquorum, and another which is currently being serviced at a watchmaker who I know.  I heard of another one and that is it.  So at this point, I know of 4 pieces.  Not sure how many were made, the existing pieces are either in 18k Gold or in Steel/Gold.

Watches-and-art-005 sWhile this is a great and rare collectible Piece, I don’t really know much about the reason of the German writing.  I wonder if any collector out there can shed a light on it?  Maybe there is not really a specific reason and it is just another part of the Rolex myth?

Watches-and-art-006 sI like to find such rare pieces, watches that hide a secret history and I enjoy researching until I find out the truth, if there is a truth behind it that is…

This 1950s Rolex Datejust 6605 is for sale and can be acquired (it can be viewed in Germany) for 3000 Euros.  For more Information, feel free to contact Boris at
