When it premiered replica watches in 1945
When it premiered replica watches in 1945, the Rolex Datejust was the first automatic, watertight wristwatch with chronometer-worthy rate quality. It embodied all of the innovations Rolex had developed for wristwatches up to that time, including a date display in a window at 3 o’clock, where the date switched automatically at midnight. To achieve this feat, intermediate wheels in the movement tightened a spring mechanism that advanced the date disk. The Datejust is named for this instantaneous “just-in-time” date switching.
Thanks to a movable finger in Rolex’s new automatic Caliber 3235, which powers the Oyster Perpetual Datejust 41 we’re reviewing here, the date can be reset manually, quickly, and whenever desired. Simply pull the crown out to its middle position, turn it counterclockwise, and the date advances smoothly and accurately. The ergonomic improvements that Rolex made to this caliber, in the interface for making manual adjustments, are very noticeable in practice. The winding stem engages securely in each position so the time can be reset precisely. The crown turns with replica watches uk buttery smoothness. The hands move with no play whatsoever, so the minutes hand can be positioned with its tip perfectly tangent to the desired index. The seconds hand can be stopped at the full minute easily because the screw-down crown’s stem is inserted into a long tube and the unscrewed crown is easy to grasp. Screwing the crown shut again is very secure, with a noticeable spring resistance. This is characteristic of the Twinlock system, which Rolex invented in 1953.
The Twinlock system’s interplay with the Oyster case guarantees that the Datejust can resist pressure up to 10 bar, which corresponds to the conditions at a depth of 100 meters below the water’s surface. Two insulators help ensure watertightness: one is located in the winding crown while the other is situated inside the tube. A line under the Rolex logo on the winding crown of our steel Datejust shows that our test watch has the Twinlock system. Gold Oyster cases have two dots on the crown to indicate the presence of the Twinlock system, while platinum cases have one dot.
Our Datejust’s newly designed Oyster case has a middle rolex replica piece milled from a single block of 904L stainless steel. A smooth, polished stainless-steel bezel surrounding a flat pane of sapphire seals the case from above. The Cyclops magnifying lens above the date window wasn’t added to the Datejust until 1954. It performs its practical purpose thanks to its magnifying effect and the anti-reflective treatment on both its surfaces.
