List prices in the US are generally higher than in Europe or Asia but the trade discount extended to the dealer is more or less the same. The Omega Seamaster Pro Automatic Ref. 2531.80 (James Bond) retails for 20% more in the US than in these parts.

There are plenty of watch dealers in the US who either (parallel) import their watches or buy from an importer, as opposed to buying from the local distributor. In most cases, you'll find these dealers can offer you a better deal than an authorized dealer. What you need to look out for is the validity of the warranty. As long as the warranty card has been stamped by an authorized dealer, it doesn't matter who you have bought the watch from. If you ever call upon an authorized service centre, simply maintain that you bought the watch from the company that stamped your warranty card while overseas on business.
