Modern Classic. The Rolex Datejust is one of the oldest models in the Rolex line-up. Since its release in 1945, the Datejust has evolved substantially but still maintaining its look. The Datejust line-up has expanded to include the widest variety of variants, a distinction it shares with the the Rolex Cosmograph Daytona.
The Rolex Datejust, was initially offered only in all gold, back in the day when it was Rolex's flasghip model. Gold and stainless steel versions and all steel versions with bracelets and models with leather straps appeared later. The most audacious variant of the Datejust is the Datejust Royal Black.
Rolex Datejust Royal Black. The Rolex Datejust Royal Black is a standard 36mm diameter datejust which comes in two variants. Once comes with a 18K white gold case, a bezel set with 60 baguette diamonds, black and diamond paved dial, diamond hour markers, and black rubber and galuchat strap set with 10 diamonds. The second model is nearly identical to the first but comes with bezel set with 60 baguette black sapphires instead of diamonds and has bezel edge and endpieces set with diamonds.
How much does all this cost? With the diamond bezel the retail price is US$70,600. With the black sapphires on the bezel, an even more costly, US$75,350. You can expect 20% or higher discounts on this watch.
Movement. Mechanically, it is identical to the typical Datejust. Inside you have the tried and tested COSC certified Rolex 3135 self-winding movement which produces 28,800 vibrations per hour (4Hz) and which has a fifty hour power reserve. The date is displayed in the 3 o'clock position under a magnifying "cyclops" lens. The watch is water resistant to 100 meters.
