Usually, people who collect watches do it for the love of the watch and not for the investment. If you are looking to get a return on your investment, then you might want to consider the Rolex Sea-Dweller Deep Sea.  The Sea-Dweller is a huge 43mm stainless-steel wristwatch with a titanium back, waterproof to an amazing 12,800 feet, and equipped with a gas-escape valve (the modern reinterpretation of Rolex’s first Sea-Dweller). Rolex does not disclose how many units they will produce, but we can assure you, it will not be many. So if you are looking for an attractively priced watch from a brand that always puts out amazing timepieces then the Sea-Dweller is a watch you might want to have on your wrist as you Dwell the depths of the ocean.  [$8,975 at rolex]
