Date Sizes While the first sizes of the Datejust and the Date were 36mm and 34mm (respectively), Rolex did add more size options to both collections over the years. For instance, somewhat puzzlingly, Rolex has in the past produced the Lady-Datejust and the ladies’ Date with 26mm cases, and the mid-size Datejust and mid-size Date with 31mm case sizes. However, perhaps for greater clarity between the two models, Rolex has since discontinued all of the smaller Date versions and currently only makes the Date 34. Additionally, Rolex has also ceased making the Lady-Datejust 26, replacing it with the Lady-Datejust 28. Furthermore, over the course of the last decade, Rolex has also added larger options for the Datejust.Rolex Datejust SizesThe Rolex Datejust has always offered far more metal choices and different style options compared to the Rolex Date. Although there are some vintage and discontinued Date 34 models in solid gold and two-tone steel and gold, Rolex has now simplified the choices to just two: full stainless steel or stainless steel with a white gold fluted bezel, both of which have 34mm cases and are fitted with Oyster bracelets.
