There are four English language fora, buy from the TDs on any site you are a member.
Also none of our TDs are supporters of the forum, we prefer to keep our independence.
If you want to go it alone, do so.
What we do here is share information, if you read some previous posts you would see members talking about where they buy there watches and parts.
I mostly buy from Phong and his son Jensen, they are not TDs here or anywhere else, though I would welcome them with open arms, but are openly discussed. These are very high end reps, but not 1:1, nor Swiss made, you didn't ask about reputable sellers, you specifically asked about known scam sites
