The purpose of this forum and the others like it is to protect watch hobbyists from scam sites.
If I gave you a short list of bad dealers, 10 people would be be all over me.
The dealers listed on this site have been with us for at least two years and some close to ten. They have a proven record of service and a reasonable level of accuracy in their web pages. Photos of the actual watches, not pictures of the genuine pieces; honest about the origin of the movement .. Swiss, Asian, etc .. Honesty about sapphire crystals or normal glass (synthetic sapphire)
Basically you get what you order in a timely fashion and if it's broken when you get it, they accept returns for repair.
Enjoy your new hobby.
