? Noob Maker, Mr crème De La Crème, Featured Products:
Rolex: Submariner Steel one, Submariner SS/YG wrapped, Explorer, Seadweller, Milgauss, GMT Master, A Few Daytona, Day Date 41mm, Date Just 41mm. They bought real one to make replicas, and update new version every year. In European Market, the customer like them very much. Their quality control is very nice, the watches are not easy to have problems. Audermars Piguet: Royal Oak Diver Series, Royal Oak Offshore Chronograph, but after J12 factory making the AP, their AP can not sell easily, that is the reason they sold many AP Special price in 2015. Breitling: Many Navitimer, Super Avenger, Super Oceans, Bentley, Chronomat. And many are out of stock , before customer orders them, you must let the dealer check if they have in stock. Omega: A few Planet Oceans, but sell not good, after they sold, they should not make any more. Panerai: Their PAM111 is best. Many other Panerai they made also very nice, but many watches, after sold out, they didn’t make any more. We think the main reason is Z Factory, KW factory, H Factory make the same designs and price lower. Jaeger LeCoultre: Master Compressor Diving Navy Seals BlancPain: Fifty Fathoms
? ZF Maker, Featured Products included,
Tudor : Black Bay , Titanium Pelagos , Fastrider, Black Shield. Panerai : Bronze PAM382, Ceramic PAM508, PAM438, PAM 127, PAM217, PAM389, PAM359, PAM604, PAM616 etc. The Panerai, many movements they modified to Panerai movement looks, like P9000, P3000. Some hand-wind watches.

Their Seamaster Spectre 007 is very hot. Seven Friday: Many Seven Friday Watches
? J Maker, also named J12 factory, Featured Products:
The Boss of J Factory made a lot money on replica Chanel J12 watch, That is the reason we named it J Factory. Now, they didn’t make Ceramic Chanel any more. Audemars Piguet: Royal Oak 15400, 15450, Royal Oak Offshore Diver, Steel one, Ceramic one, Forged Carbon one, Many Royal Oak offshore Chrono seconds @12. After JF make the Audemars Piguet, Noob can not sell the Audemars Piguet easily. All seconds at 12 Asian 7750 movements were monopolized by one boss, that is the main reason the AP replicas are more expensive than other brand. Of course, their details are made perfectly. Rolex: Submariner 116610 LN, Submariner 116610 LV, Daytona, Yacht Master I 40mm, Daytona, Milgauss. Their Rolex almost have the same quality as Noob factory ones. We guess Noob’s boss should be afraid of their Rolex Watches. Cartier: Tank Series, Calibre De Cartier, Ballon Bleu De Cartier. Hublot: They also make Hublot Big Bang before, but they didn’t update to newest version.
? BP maker, Featured Products:
Rolex: They made most designs Rolex watches, Submariner, GMT, Daytona, Explorer, Milgauss, Data Just, Day Date, Cellini ,Yacht Master, and so on. Their main products are Rolex. Their watch looks nice, but their quality control is not perfect, their watches always have many small problems. If you want their watches, please wait patiently, dealers need more time to quality control them. If you want to lower price of their Rolex, many their Rolex watches can put A21J in the same quality case as A25J. Their parts like hands, bracelet, crown, dial are easy to get. IWC: They made the Big pilot earlier than other factory, So we named them BP factory, but their big pilot didn’t update to 1:1 version like ZF. So they do not sell well. Breitling: In 2015, they began to make many Navitimer, Bentley, Chronomat. Audermars Piguet: Royal Oak 15400 41mm. Omega: Seamaster Professional Diver, Planet Ocean, Seamaster 300m, Seamaster Chrono one. Patek Philippe: A few Nautilus, Nautilus Chrono, etc.

Tag Heuer: Grand Carrera, Carrera 1887, Aquaracer. Cartier: A few Santos, Ballon Bleu De Cartier. Patek Philippe: A few Nautilus 1:1 case. The V6 factory quality are very nice, only their parts like hands, dials are not easy to get. Zenith: Pilot Pilot Type 20 Steel, Bronze. IWC.
? T Maker (TF):
Specialized in many tourbillon watches of Audermars Piguet, Hublot, Jaeger LeCoultre, Breguet, Franck Muller, Patek Philippe, Vacheron Constantin, IWC, Cartier etc. Almost all real Tourbillon movement watches are from them.
