1975 Rolex Datejust (Ref. 1603) "Silver 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.

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.

Worn with ease in any setting, the Datejust is a classic for a reason. We love the early Rolex Datejust for its simplicity and its understated sophistication and this example is no exception, featuring a bright and beautiful silver sigma dial.
