Very close to purchasing a Patek Gondolo from an established dealer out of town. Since they do have a liberal return policy I want to verify it's completely legit. Are there places to take it to have it inspected and verified? I know ebay offers that service for watches over $2000 now (probably since there was so much fraud). I want to verify that everything is legit since I've heard of dealers that will replace the gold buckle sometimes hoping nobody notices. Also, what about the components inside the watch? Can those be inspected also?
