To mark the 40th anniversary of Rolex, the Datejust is one of the best-selling timepieces of Rolex. The model was released in 1945, to initially honor the victory of the Allied group in World War II and Wilsdorf thought of giving it a name of “The Victory,” but it was changed to “Jubilee” and soon to “Datejust.” Many people most especially the Rolex lovers thought about the Datejust as a variation of the Bubbleback which was released in the 1940’s, where both were known to be the Overtone of its domed back.
Rolex originally offered the Datejust in 18kt yellow gold and was offered in white gold, platinum or stainless steel after seeing a high success. The circulation of the two-tone Datejust models occurs in 1962 and has an option of an Oyster and Jubilee bracelet or a leather strap. The replacement of the coin edge bezel with the latest fluted bezel that has a larger size crown was introduced first in the Datejust models. The Datejust 6605 was first released in 1950’s, and there is a magnifying bubble that lies over the date on the watch’s crystal. Moreover, the Datejust model 1625 or more commonly known as “Thunderbird” was released in 1956 which has a feature of a golden bezel Turn-O-Graph.
During the 1970’s, some improvements led to a change in the Datejust’s original shape. One of the changes is the ability of the Datejust wearer to have a quick adjustment on the date function without turning the crown over and over again. This impressive feature is called the “Quick-set” which is a solution in one of the biggest problems of Rolex and all of the Rolex models have this feature by the year 1983. Also, the new Datejust has a sapphire crystal as a replacement of the old plastic crystal. The improvements of this new features include the longevity and aesthetics of this timepiece. Also, it has an improved water resistance and is a scratch resistant.
Furthermore, the modification of the four case reference number to a five digit number was done during this time. The Oyster date was another feature that was introduced as well. The only distinctive feature was its 2mm size since the Datejust’s midsize version was around 80% of its original size.
