Rolex very, very rarely introduces all-new models, as a matter of fact, the last Rolex model introduced before the Yacht-Master was the Rolex Daytona which was introduced in 1964. Rolex introduced the Yacht-Master in 1992, so it took them 28 years to come up with an all-new model! Just for frame of reference, it took Rolex another 20 years to come up with another all-new model, which was the Sky-Dweller, which they introduced in 2012.
While BaselWorld 2012 saw the introduction of the beautiful Nautilus with a white dial, perhaps the most interesting sport watch from Patek Philippe in the past two years isn't a Nautilus at all. You see, the Aquanaut has always been the other sports watch from Patek - considered by some "Nautilus light." So it was with great pleasure that in 2011 we saw the launch of arguably the coolest Aquanaut to date, the Aquanaut Travel Time 5164A.
