1973 Rolex Datejust (Ref. 1603) Grey Sigma Dial

The Rolex Datejust is one of the most iconic and most beloved Rolex watches ever made, even though the Datejust was launched in 1945 it has remained a timeless classic and is instantly recognizable as an item of refined quality and functional design. The Datejust can be worn just as easily with a suit as it can be with jeans and a tee-shirt. The DateJust would make a great start for a new vintage collector, or be a great addition to an expanding collection.

This specific 1973 Datejust Ref. 1603 retains its original grey "Pie Pan" Sigma dial which is sought after among collectors. A Sigma dial is a Rolex dial named for the letters printed at the bottom of the dial at the 6 o'clock position. Most Rolex dials are commonly marked with “T Swiss T,” under the 6 o'clock marker, however, a Sigma dial is marked “σ T SWISS T σ.” This signifies the use of gold components within the dial.

This piece would make a great start for a new vintage collector, or be a great addition to an expanding collection. We love the early Rolex Datejust for its simplicity and its classic sophistication.
