Rolex Submariner 16613

Collectors call the 16613 the Bluesy, the two-tone Submariner that trades tool-watch restraint for steel and gold and a blue that shifts with the light. The sunburst blue dial sits under gold hands and markers, matched to a blue aluminum bezel insert on an 18k gold ring. The 40mm steel case runs on a two-tone Oyster bracelet, gold center links between steel. Inside is the automatic caliber 3135, a chronometer good for about 48 hours. This is the five-digit generation, slimmer than the ceramic Subs that followed, offered as the watch only. Among Rolex watches, the Bluesy is the warm one.
