Removing serial numbers is still being done. For me, the grey market dealer would have to offer a really significant discount for me to even entertain buying from them. Not only do you not get the warranty from the manufacturer, you aren't even sure it's really a brand new watch. Example, you go to an AD, buy a new Omega for instance. You wear it a day, and decide that you really don't like it. You take it back, and trade it for something else. The AD cannot sell this as a new watch, but they can darn sure sell it to a grey market seller who in turn resells it to you as a new watch. Same thing with watches that develop a problem right after purchase. Replaced and resold. I would expect that these occupancies are a tiny part of the total grey market. The vast majority are coming from AD's who sell to grey market dealers that are not in competition with the AD, geographically. AD's use this method to unload unpopular models and slow sellers, but they also use this to increase the volume of watches and possibly qualify for a bigger discount. I don't know that all manufacturers have sliding scale discounts, but lots do. The more the dealer buys, the less the price per unit.
Watch manufacturers really don't like grey market dealers, as they establish the price of a particular watch at a price point well below the manufacturers suggested retail price. Also it creates a PR problem when someone tries to get their watch repaired under warranty and the manufacturer refuses because it is a grey market watch. One year out, the watch owner doesn't remember the fine print that specified the watch was not covered under the manufacturers warranty! The owner is now mad at the company because they won't is his watch
