The Rolex Sky-Dweller 326939 was the most hotly anticipated watch at Basel World 2012. This new sports watch is an updated version of the original Sky-Dweller model, which was originally designed for use by aviators who needed to keep track of time in multiple places easily. The dial features a red triangle that always points to the wearer’s local time, while the main hands can be set to a second time zone. Not only can this watch track time in two locations, but it also offers a patented annual calendar which intelligently distinguishes between 28, 30 and 31 day months. This watch, created with 14 patents, offers unparalleled reliability and represents Rolex innovation at its finest.
