Rolex Submariner Date Sultan Dial Two-Tone 16613 with papersThe subtle bling Sub This is something off the beaten path and something of an undiscovered gem, in our opinion. This two tone Sub is fitted with a factory original so called Sultan dial, where the hours are set with diamonds and sapphires at the quarters. This gives the watch an entirely different look and is very on trend with the current interest in gem set Rolex sports watches. The no lug holes case remains strong, with nice lines and fat lugs.
