Had this on a couple of watches. Both from amazon, was worried like yourself. But it's basically something to do with you go through amazon for the warranty as opposed to the manufacturer. Also regards the price, you can get lucky with amazon or ebay if you are there at the right place at the right time. They more than likely have a price alert setup from a site like price spy or camelcamelcamel. Two of my watches I got this way with over £100 saving or so. This must be their full time job because it's basically a constant tracking of prices, and it is really frustrating and time consuming. They at most will be making max £100 on larger items.
