Nautilus and Aquanaut are two most popular series of Patek Philippe, some people like full stainless steel watches will choose Nautilus, while people who like their watches to be more sporty will choose Aquanaut, overall, the need for those two watches is big. So, here in China, a lot of factories make the replicas of Patek Nautilus and Aquanaut, like ZF, PF, PPF, GR, etc., their quality is really good, sometimes my clients are confused and do not know which one is the best, actually whatever version they choose, the quality will not be bad. Maybe the difference between these factories is very subtle, you do not need to care too much.
However, about Aquanaut chrono, only a few factories make the replicas, among them, I think OM makes the best one. There are three models OM has made, black, blue and orange. Because the movement installed in these watches is Asia Valjoux 7750, so their case is a bit thicker than that of real watch.
The Aquanaut chrono looks good, compared with basic Aquanaut 5167, it is added with extra chronograph function. On this replica, OM equipped an Asia valjoux 7750 movement, actually it is based on a Chinese chronograph movement, OM factory added some plates on the top and made decoration on them, like the golden engravings and SEALs you see, so the entire movement will look closer to real Patek Calibre in outlook. Because of these added movement plates, the whole watch looks thicker.
The finish on the case is good, you can clearly see the polished round bezel, the edges and corners of the case are also well polished, smooth and round corners guarantee good wearing comfort. Plus the black rubber band, you will feel comfortable when wearing it on your hand. On the black dial, you will notice the small subdial and two orange hands at the first time, both hands and hour markers are applied with lume material. This Aquanaut chrono replica is good enough, it is 14mm, maybe a bit thick for some people who have seen the real watch, but in a short period, no other replicas can be better than this one.
