Short reveiw of the History of the Rolex Datejust

In 1945, to commemorate the 40th anniversary, Rolex wanted to create a most distinctive cheap watch that is different from all the other timepieces at the time. The result was the first self-winding, water resistant replica watch with a date window on the dial. This groundbreaking model was the renowned Datejust. 
The original model was named Jubilee Datejust, Reference 4467. It is the same name of the brand’s all-new Jubilee bracelet, which has since become a staple for fake Rolex. The initial reference was only available in 18-karat gold and showcased the brand’s iconic water resistant Oyster case with a fluted bezel. To put in the larger Caliber 710 movement that enabled the new date function, the model featured a convex caseback. Soon the Datejust became the flagship model of Rolex replica.
The Datejust embraced its first major update a decade after its first release. In 1954, Rolex debuted their all-new Cyclops lens on the Datejust. This magnifying lens is directly above the date window, which makes the numbres looks two and a half times bigger. Today, the Cyclops lens is standard on Rolex watches and is one of the trademark features of the repica watches.
In 1955, fake Rolex created a special version of the inexpensive replica watch called the Turn-O-Graph, which was later nicknamed the Thunderbird. United States Air Force pilots were rewarded this unique version when return home from combat missions. What distinguished it from the other models was the rotatable Turn-o-Graph bezel for which the watch was named.
Rolex made another major update to the Datejust in 1957. This change was more technical than aesthetic. The movement was chagned to the Caliber 1065 movemen which is smaller, more efficient and thus altered the design of the Datejust. It eliminated the need for the domed caseback and created a more streamlined design for the model.
