I believe that you are completely correct. it's going to get harder and harder to get quality watches with any degree of safety. I really, really don't like WU, although I will reluctantly use it if I have to, but it's only going to be with someone I have done business with and I have a certain degree of trust. Idiots who open PayPal disputes are at the bottom of this, as it basically paralyses the dealer when their account gets frozen. Having said that, some blame needs to be shared by the dealers as well. If they were a little more accommodating, and did a better job of responding to complaints, possibly some of these disputes could be averted. I realize that there are some people out there who are just idiots. they order a watch, and expect that it will arrive on their doorstep within a couple of days, totally unrealistic. they start bombarding the dealer with emails every half hour demanding to know why they haven't gotten their watch? Then when it arrives, they nit pick it to death, even though had they read the reviews, they would have known about that particular model's flaws. Or some like the poster above who probably has never a mechanical watch in his life, who can't understand why it stops after a few hours of inactivity. Never had a clue that you needed to wind it first and then wear it!! I would bet that a very high percentage of problems that are encountered are things that are owner created either out of carelessness or ignorance. But unfortunately, the dealer/factory gets blamed for a lot of this.
AFA the movement substitutions, that is unconscionable. Buyers have a right to be angry when they pay for a certain model or grade movement, and open their watches and find out that they actually got a low grade, unreliable, probably un-repairable movement. If the dealers claim that they didn't know, then they need to know. Ignorance is no excuse for breaking the law. I know they probably deal with large numbers of watches every day, but somewhere there has to be accountability. If all the dealers told the factories, I can't sell these watches with these POS movements, I would bet that something would be done. Just saying, "I had no idea that they were substituting these movements for the higher grade movements", is no excuse. That's like me buying a new car from a dealer and while driving it home, the transmission seizes up. turns out the factory forgot to put transmission fluid in the transmission. That's why dealers do a pre delivery service and check, to prevent those types of problems. the watch dealers should do the same thing as well.
If we were paying 50 bucks for reps, I would say, what you see is what you get, but we are paying 700-800 USD for bone stock reps. At that price, there should be some quality control. If shenanigans continue, I can see a lot of folks getting disgusted and leaving the rep game, or doing like I do about 95% of the time, buy M2M. At least when you buy from another member, you can ask questions, ask for good clear photos and have a good idea of what you are getting.
