An attractive example of a Rolex Datejust 1603 from circa 1973 featuring a rare "sigma dial". This reference 1603 sports a beautiful black sigma dial, fully serviced 1570 movement and comes with a Rolex service pouch.
This Datejust reference 1603 features the collectable "sigma" dial. A sigma dial is identified by the "σ T SWISS T σ" text at the base of the dial with "σ" being the lower case Greek letter sigma. At a time when gold prices quintupled between 1970 and 1974, the sigma marks were intended to show the use of gold on the dial and increase its perceived value. For a fascinating read on Sigma, dials head over to Hodinkee and their article here.
Overall this watch is in excellent condition, with a clean dial, good thickness to the case and a fully serviced movement. The watch comes fitted with a jubilee bracelet, visually it's in decent condition but does have significant stretch to it.
All in all, this is a fantastic example of the highly collectable sigma variant of the Rolex Datejust 1603. Be quick as we don't suppose this will hang around!

Do watches come with original box and papers?
It depends on the individual watch. You can see details under "The Basics" heading on this page. For the majority of vintage watches their original box and papers have been lost to time. Whilst they are nice to have, it’s important to note that “box and papers” DO NOT authenticate a watch despite what many in our trade say. It’s also important to realise alot of sellers (including some of the most well known in the UK) put together full sets of box, papers, hang tags etc by buying blank paperwork and boxes in the secondary market. This is a very regrettable, but unfortunately common occurrence in the trade but something we will never do!
How do I know it will fit?
For metal bracelets we provide the size it will currently fit in the description section of this page. If this measurement is too large or too small we are able to assist in either adding or removing links. We also offer this service, post service on a at-cost basis (i.e. we don't add a margin).
