Today, however, we’re going to review one of the models in the Rolex Datejust 41mm collection and compare it to the Oyster Perpetual 39mm to provide you with the key information you need to see which one is best for you.
First of all, these are what most people would call excellent entry-level Rolex replica watches, and they make up two of Rolex’s ten most affordable stainless steel models for men. They both have a black sunburst dial, and by design, they are conservative models that can be worn both when dressed up and for casual use. 
Why is it named the Oyster Perpetual Motion? The patented Oyster case has been part of Rolex’s history since 1926 when a new seal was provided by screwing the bezel, caseback, and winding crown to the middle case of the watch. The name Perpetual is due to the automatic winding that occurs with the movement of the wearer’s wrist. The kinetic energy of the wrist movement winds the rotor in the watch movement, thus refilling the power reserve. This in turn makes the watch run in a permanent way.
Is the Oyster Perpetual worth buying? Yes, it is a great watch with an internal self-winding movement that outperforms most mechanical movements in terms of precision and accuracy. In fact, most fake Rolex movements have a Super Chronometer designation, which means that it is twice as accurate as the minimum COSC specifications, which is already considered excellent. So, for the purposes of this comparison, it’s not as if either one is necessarily more accurate than the other.
Generally speaking, new entry-level replica Rolex watches for men are limited. The slightly smaller Rolex Oyster Perpetual 39mm collection has similar aesthetic features such as the Oyster strap and dial color, and the case size weighs in at a smaller but classic 39mm.
The hands of the Oyster Perpetual 39 mm collection are made of luminous material and the luminous hour markers are a little different from the square printed 5-minute markers. On the other hand, the Datejust 41 mm uses printed numerals for the 5-minute intervals and combines them with the same type of luminous applied index hour markers. While the case of this watch is only a few millimeters smaller than the Datejust 41mm model we reviewed here, and while the 39mm Oyster Perpetual is less expensive, there is a big difference inside the watch, and if you’re still in your price range, there are great reasons to choose the 41mm Datejust model over the 39mm Oyster Perpetual. Whatever the one you like is just the best.
