Two dials, one after the other. The -0001 runs 2014 to 2018 with black lacquer, white gold applied Maxi markers, and Chromalight lume. The -0002 takes over in 2018 with a matte blue dial in the same furniture layout. Both carry the green GMT-Master II text that marks post-2007 GMT-Master II dials.

The bezel is the story. The 116719BLRO was Rolex's first ceramic Pepsi GMT and the first red-and-blue Cerachrom insert the brand brought to market. Rolex had already proved two-colour ceramic with the black-and-blue 116710BLNR in 2013, but red was the harder problem. Firing red Cerachrom takes different kiln chemistry from blue, and getting both colours into one insert without a muddy join at the boundary is the patented part of the process. Solving it here is what made later ceramic Pepsi production possible.

The crystal is sapphire with a Cyclops over the date window at 3 o'clock. The crown is a standard Triplock screw-down with crown guards. Water resistance is 100m, unchanged from the five-digit GMT-Master II and consistent across the whole modern ceramic GMT family.
