By Peking.. do you mean.. BEIJING?????
not sure about reps in Beijing.. but maybe someone will be able to help you out! The general consensus about reps in china seems to be that it generally is not a better deal to buy them there. especially being a westerner. The price for your (let's say) UPO will end up being more or less the same as if you bought it through one of our trusted dealers here. Haggling won't work, since by the time you get to the little watch stand and wait for them to get the "good merchandise" from the back, they know they can sell the "good merchandise" for a certain price online.... Which is what they tend to prefer.
You have to remember, the watches we buy are coming from the places you're going to in china. They know exactly how much a new PAM 111j is worth, since they're often the ones with websites up!
In any case, good luck, there's always the possibility that you'll find a steal!
