The brands set prices for each market separately from what I understand. The prices will be relatively close, but will be fixed for a year (catalog year) in each country or market. Prices at the boutiques owned by the companies themselves usually have the least ability to discount but they will have more access to models and more variety in stock. Authorized dealers in certain markets have more flexibility for discounting depending on the distributor. Sometimes the distributors are local companies, sometimes they are a subsidiary of the watch label specific to that country or region. Some brands disocunt more than others. Patek is going to discount the least across all countries. As is Rolex, but...(comment withheld in order to avoid any wars) Sellers like Wempe, which operates in a lot of countries, has tremendous access to different special edition models, so they probably can get you nearly every watch, although they won't discount special orders like they will with items in stock. If you find something at a boutique that isn't a special edition I'm sure the biggest retailers can get it for you with a bit of a discount. There are also going to be some special brands with much more availability like Roger DuBuis than there would be anywhere else. Good luck.
