Replica Rolex Datejust II

Rolex expanded the Datejust line back in 2009 with a 41-mm version dubbed the Datejust II. Other than its larger case, the Datejust II shares all the details that made the 36-mm original so successful. The caliber 3136 has a larger base plate, a 48-hour power reserve, and chronometer certification from the Official Swiss Chronometer Testing Institute (COSC).
