WOW!! You are asking about a books worth of questions right off the bat.
First off, both of those sites you linked to are scam sites. You will pay those people big dollars and get a 50 USD junk street vendor quality watch, if you get a watch at all. If you want a replica, take mine and most everyone here's advice, buy from a trusted dealer on this or the other reputable Replica sites, RWI, RepGeek, or RWG.bz. If you want to donate your money, I can send you my PayPal address and you can send it to me. I'll put you on my Christmas card list and at least you will get a nice card every Christmas!!
My advice to you sir, is before you buy any replicas, you need to do a lot of reading and research. There are lots of discussions here that will answer your questions. Here is my take on buying replicas and movements. The simpler the watch and movement the better chance it will be reliable. that is not a 100% guarantee, because these are replicas, and most of the movements are replica movements, which means that they are copies of ETA Swiss movements, they are not ETA Swiss movements. So if you buy say a Hublot replica with a copy of the ETA 2824 or 2836 movement it should be OK, As you go further up the line of complications, the more likely they are going to be troublesome. So the next in line would be a chronograph model which uses the A7750 movement. If you buy a chronograph with the seconds dial/hand at the 9 o'clock position, commonly referred to sec@9 , that is the normal position for the 7750 seconds hand, it should be OK as well. You will not get and ETA 7750 movement in any rep watch today. No matter what those scam sites tell you. ETA 7750 movements are hard to get and the price is more that 300 USD for a movement, so the rep manufacturers are not going to put a 300 USD movement in a 500 USD watch! So the next step up the line are chronographs with the seconds hand in a different position. These would be the Rolex Daytonas with the seconds at 6 (Sec@6) and the Audemars Piguet Royal Oak Offshore (AP ROO) models with the seconds at 12 (sec@12) . These are what we commonly refer to as "time bomb" movements because they have a history of problems. Some people say that they have had several watches with these movements with no problems, but personally, I have 5 AP ROO's, and three of them have been trouble free, and the other two have been nightmares. So, personally, until you get a little more experience with replica watches, and get to know people who can repair your watch if it breaks, I would stay away from these movements. Stick to the simple non chronograph movements or the watches that have the A7750 movement but the seconds hand is in the correct position (Sec@9)
AFA tourbillion movements, I have no experience, never owned one, and I don't know of a single rep repair person who will work on these movements. I believe that Seagull makes a pretty reliable Tourbillion movement, but I don't think it is used in rep watches unless it's the really high end ones that are around 1k. Another problem with these, most of these watches sell for a couple of hundred thousand dollars, so are you able to pull one of those off. all it takes is one of your buddies to see your watch, Google Hublot Tourbillion, and partner, your busted!!! So unless you are driving a Ferrari or equivalent, or just flew in on your private jet, I would stay away from watches like the tourbillion.
