I'm going to be supportive as you are a VIP member and have contributed to this forum.
Right now, there is one maker that stands out from the rest. That is TC Submariner. There is a section in the reputable dealer area that has this contact details.
TC Sub:
The pros:
It is genuine specification so genuine rolex submariner parts will fit (i.e., the external parts like insert, crown, crystal)
It is pretty much plug and play and it is the best submariner out of the box at the moment
TC puts the watch together for you personally so QC is there also
The cons:
Expensive - at around $550 plus shipping, it isn't a cheap replica but the quality and the fact that is so close to the genuine piece makes it special
TC can be slow at responding. He is inundated with orders so can be slower in turnaround replies and the purchase to receiving can take up to 5-6 weeks as he needs to put it together for you
The MBW (or variants of it):
More or less a prequel to the TC. It also accept genuine parts (the original man behind this was BK - believe he still has a section in the sellers area) but believe he doesn't sell anymore. However, you can find these from members selling them from time to time. Generally cheaper than the TC but may be around the same price given most members have upgraded it with gen parts at some stage.
The noobmariner:
One of the old school versions that can still be found from time to time from member selling them. They were cheap (around $120 a pop), doesn't accept genuine parts but for what it was worth, still great quality and a great daily beater. The serial starts with a "F"
The TW version:
Recently got my hands on one of these. Similar to noobmariner but from different maker. Doesn't really accept genuine parts but a decent daily beater too. Serial starts with "D"
After these above 4, there are still dealers selling the 16610 classic but many have flaws. Personally, I have seen the Trusty Watch version in the flesh and its not great. Aside from the decent pearl, the wok effect is strong and the doesn't accept genuine parts. I havent bought others but would avoid the cheaper dealers as their stocks are not great either.
Hope this helps.
