Notes: 41mm Rolesor case in stainless steel with 18K white gold fluted bezel, rhodium dial, diamond hour markers, and stainless steel Oyster bracelet with Oysterclasp and Easylink extension link. Water resistant to 100 meters.

Mechanism: The 3136 movement was designed to have the feature set of the 3135 but is able to take advantage of the larger space allowed by the new Datejust II 41mm case. The calibre 3136 is two and a half millimetres larger than the 3135 and it has been consolidated into the e.g. 41 mm sized Rolex Datejust. While other manufacturers just call it a day by repackaging the same calibre into a larger watch case, the brand has opted instead to launch an entirely new movement. Its dimensions have been fine tuned to meet the current demands of everyday wear that’s placed on Rolex watches that have surpassed the 40 millimetre mark.

Calibre 3136 is a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 3136 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The 3136 features a Parachrom hairspring and high performance Paraflex shock absorbers developed by Rolex, offering greater resistance to shocks and to extreme conditions. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.

Family Notes: No other watch in the Rolex catalog is as timeless or iconic as the Datejust. In the over 7 decades that the Datejust has been in production, the model has seen numerous upgrades, including the use of a larger 41mm Oyster case via the Datejust II. Similar to the 36mm variation of the brand's iconic dress reference, the Datejust II is available in a variety of feature sets.
