I think Trevor has the same watches as anyone else. I asked him to get me a vintage Daytona I found on another site and he got it to me for $75 less.
yeah most dealers have the ability to cross sell the same product, from the same factory, even though it may not be listed on their own site.
but as you have discovered that some dealer(s) sell less for similar item on another dealer(s)' catalogue, i've found that the reverse is also true.
i have a dealer who is hesistant (read: not willing) to sell a watch which is priced very competitively by another. Usually i would order a bunch with the same dealer as prices are generally aligned with minimal difference. But as some have discovered, there are items where one dealer can offer significantly less.
