Andrew it is down to you where you buy from, but i think you will find that sino has access to the same factorys as our TDs here but you may also find that there are a few restricted productions that only go to the cartel dealers.
Stick around and learn a bit, we can all learn more than we already know.
you may know that many of the new watches use a colurless AR now in particular panerai
This site has over 10 years of experience in the rep world, some of the members here are fully qualified watchsmiths, others are world class modders of watches both rep and gen, we have experts in almost every field of horology, there is alot here to read if you have an open mind. This is the grown up site where we give people the benifit of a fair trial, dont ban them at the first hickup, (But it is always worth reading the rules) and take the time to educate and support, there is a real comunity here both in the cyber space and in real life!
Thank you
