Unless its a steel Rolex, ask for a 'best cash price' if you are going to buy new. You will probably get 20-30% off of retail for a Baume & Mercier.

There is nothing wrong with buying preowned at all. Here's the plan for never getting hosed on a pre-owned watch deal:

Forget the watch, always buy the seller.

Ask for references and check them on timezone and watchnet. A 3 day inspection should be a condition of ANY high dollar watch deal. Its standard protocol when dealing with expensive watches so don't consider buying a watch without it. When you get the watch, get it inspected by a watchmaker or the local authorized dealer.
