I'm afraid Watch Snob's opinions and sense of judgement is best served in a fashion police magazine (oh wait, he already is).
Oh dear. Thseira, you actually tried to use a Watch Snob diatribe as justification for your argument?
Sidestreaker is 100% correct (except, perhaps, the bit about Watch Snob being entertaining - that is debatable!).
OP, if anything, the fact that Watch Snob doesn't like ML should be all the more reason to keep yours. And perhaps buy another!
Personally, I don't have a lot of interest in ML, but yours is a bit special. Rolexes, on the other hand, are everwhere - you can pick one up any time in the future. That ML would be much more difficult to reacquire.
So the resale isn't great? Then don't sell it - problem solved! Anyway, watches are about looking at what's on your wrist and smiling, not money or investment. That's what work and banks are for.
