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!
