The Rolex Submariner Date ref. 126613LB pairs Oystersteel with yellow gold in the current 41mm generation of Rolex's dive watch line. This 2023 example carries a blue dial with matching blue Cerachrom ceramic bezel, a combination sometimes called the Bluesy within the two-tone Submariner family. The bezel is unidirectional and rotating with a 0-60 dive scale, and the dial reads Superlative Chronometer Officially Certified beneath the Submariner and Swiss Made designations, with a Cyclops lens magnifying the date at 3 o'clock. Luminous hour markers and hands sit against the blue surface, finished in gold to match the case. Inside is the automatic caliber 3235, a Rolex movement offering a 70-hour power reserve. The watch is fitted to a two-tone Oyster bracelet with matching steel and gold links. Condition is graded excellent, and the piece comes as a full set with original papers dated 2024, the original purchase receipt, a Rolex wallet, and a Rolex green hang tag.
