1975 Rolex Datejust (Ref. 1600) Silver "Sigma" Dial

The Rolex Datejust is one of the most iconic and most beloved Rolex watches ever made. Launched in 1945, it has remained a timeless classic, instantly recognizable as an item of advanced quality and functional design. The Datejust’s exemplary style makes it an extremely versatile choice, worn just as easily with a suit as with jeans and a t-shirt. The Datejust would make a wonderful starting point for a new vintage collector and is always a great addition to an expanding collection.  

Vintage Rolex DateJust Ad

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. 

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 Datejust 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.

The inside of the case back is marked 1603 and is original, this is common for Datejust in this era as these parts were interchangeable between references. The Rolex 78350 Oyster bracelet with 558 end pieces is era-correct and possibly original to the watch, the bracelet retains 13 links that show almost no stretch and will fit up to a 7 1/2-inch wrist.
