In 5 years time we'll all look back at the 116600 Sea-Dweller as one of the most important of Rolex's modern production pieces. Featuring a unique case, bezel, bracelet and dial, Rolex have never invested so much R&D in such a short production run. This example, complete with its original Rolex box and warranty card, is in superb condition and perfect proof that there are still solid investments to be found a little under the radar.
