Rolex Submariner Date 116613LB 40mm (2018)

The Rolex Submariner Date 116613LB — often nicknamed the “Bluesy” — is a striking two-tone dive watch that blends Rolex’s legendary professional performance with premium luxury details. Housed in a robust 40 mm Oyster case crafted from a mix of 904L Oystersteel and 18 ct yellow gold (Yellow Rolesor), it features a vibrant blue sunburst dial with luminous hour markers and hands for excellent legibility underwater or on land. A matching blue Cerachrom ceramic bezel with a unidirectional 60-minute scale enhances dive timing functionality while resisting scratches and fading. The dial also sports a date window at 3 o’clock magnified by Rolex’s iconic Cyclops lens. Inside beats Rolex’s automatic Calibre 3135, a COSC-certified chronometer movement offering reliable performance and roughly 48 hours of power reserve. The integrated Oyster bracelet with polished yellow gold center links, brushed steel outer links, and a secure Oysterlock clasp with Glidelock extension system completes a watch that’s equally at home in deep water (up to 300 m / 1000 ft) or dressed up on the wrist with sporty elegance.
