This Rolex Datejust Ref. 1603 dates to 1973 and features one of the most attractive dial configurations found on a vintage Datejust: a rare blue Sigma dial.
The 1603 is a brilliant reference for anyone who wants a classic vintage Rolex Datejust with a slightly more understated feel. The engine turned bezel gives the watch a cleaner and more tool-like look than the white gold fluted bezel, while still keeping the instantly recognisable 36mm Oyster case profile.
The standout feature here is the dial. The blue tone gives the watch real presence on the wrist, while the Sigma signature at 6 o’clock adds an extra collector detail. The warm aged plots, original hands and folded Jubilee bracelet all give the watch the character you want from a proper vintage Rolex.

Accessories / The Set
This watch is sold as watch only, which is typical for vintage timepieces.
We place greater value on condition, originality and overall integrity than on whether a box or papers happen to be present. Many vintage watches have lost their packaging over time, and we do not believe in inflating prices with non-original extras.
If a watch does include genuine box and papers, this will always be clearly noted in the description. All purchases come with bespoke Watts On Watches packaging and full purchase documentation.
Why Buy This Watch
The Datejust 1603 is one of the best entry points into vintage Rolex collecting. It has the classic 36mm case size, the reliability of the calibre 1575 movement and enough versatility to be worn daily.
What makes this example special is the rare blue Sigma dial. Blue vintage Rolex dials are always desirable, but paired with the Sigma signature, warm tritium tone, engine turned bezel and folded Jubilee bracelet, this has exactly the sort of character collectors look for.
Every watch we sell is fully inspected to meet our exacting standards. We stand by the quality of our stock, which is why every purchase comes with a 12-month warranty as standard.
