Rolex Submariner 116613LB

**Rolex Submariner Date Reference 116613LB** The 116613LB represents Rolex's two-tone interpretation of the Submariner Date, distinguished by its blue dial and blue bezel configuration within the series. This reference combines stainless steel and yellow gold construction in Rolex's Rolesor format, differentiating it from the all-steel variants in the Submariner Date lineup. The 40mm case utilizes stainless steel and yellow gold construction, fitted with a sapphire crystal and unidirectional rotating blue ceramic bezel. The automatic Caliber 3135 movement provides 48 hours of power reserve. Water resistance extends to 300 meters. The blue dial coordinates with the blue ceramic bezel insert, mounted on an Oyster bracelet combining steel and yellow gold elements. Produced approximately from 2009 to 2020, the 116613LB appeals to collectors seeking the Submariner Date platform in precious metal combination. The reference offers the functionality of the Submariner Date series while providing the aesthetic contrast of two-tone construction and the blue colorway treatment across both dial and bezel elements.
