Rolex Model Categories
Oyster, Professional and Cellini
Categorizing the Rolex line of watches into three categories was the best I could do, based on what information I found on the website. Though all the models seem to be an oyster perpetual of some sort, I've separated them into Oyster Perpetual, Professional and Cellini series.
Some of the most popular watches from Rolex such as the Submariner, Yachtmaster and Daytona reside in the Professional series, while the classic gent's Rolexes are part of the Oyster Perpetual series, with the non-standard and more uniquely designed models belonging to the Cellini series.
