This is the replica watches new, in-house caliber 2232 (although it's not totally brand new; more on that in a minute). No, it does not feature the Chronergy escapement, but instead is fitted with a Syloxi (Rolex for silicon) balance spring. This is not the first time a silicon balance spring has been featured in a Rolex watch, but it is its first appearance inside a conventional stainless steel sports model, which is both noteworthy and possibly indicative of things to come. For a bit of context, Rolex divides its watches into two categories – no, not sport and dress, but rather, professional and classic. The former encompasses what we would associate with the Submariner, Explorer, GMT-Master II, and so on. The latter is where you will find models like the Oyster Perpetual and Datejust. Nonetheless, the OP is still very much in replica watches uk the sports watch vein, albeit in a more versatile manner.
Rolex unveiled the first movement utilizing a Syloxi silicon hairspring in 2014 with the caliber 2236. This movement was released inside a diamond-encrusted Pearlmaster – also a 34mm watch. At the time, Rolex called it "the movement for the next generation of women's models." It would go on to be featured in a host of such watches from 28-31mm. Later, we would see this movement introduced in the 37mm Everose Yachtmaster, the first watch that didn't quite fit that mold. This new OP 34 continues in that direction. Now, we just called the 2232 a new movement and, technically, that's true. But if you look at the 2236 and rolex replica 2232 side by side, you could definitely think they're the same movement.
