The Datejust 16233 measures a 36mm gold and stainless steel case, two-tone Jubilee bracelet and fluted 18k gold bezel.

In the year 1945 the first Datejust was introduced in honour of the 40-year existence of Rolex, under the reference 4467. This was the first self-winding watch with a watertight case that also indicated the date. It even automatically transitioned the date after midnight. The Datejust was equipped with a serrated bezel and the famous Jubilee bracelet, especially designed for the Datejust. The date was placed on the 3-hour mark. Ten years later, in 1955, the date-window was given a "cyclops lens", which magnifies the date up to two and a half times.

Rolex's most iconic models were produced to function as "tool watches". The Datejust, however, did not have a specific purpose. This model was supposed to be a classic, reliable, everyday watch, suitable for any occasion in day-to-day life.
