Hi.
Don't have any experience with the seller, but if you're at all concerned about the watch, have you tried going to an authorised distributor and leaning on them? In the current economic climate, no-one wants to pay retail and, most importantly, I think the dealers are well aware of this and expect people to push them more over discounts. If you can find a dealer who have had one in stock a while and go in prepared to walk away if the price isn't right, you could well see a big chunk knocked off the price - not the 50% of a second hand watch admittedly but I'd expect it to be over half the way towards it. Even better, find two dealers and play them off against each other.
