Pre-owned Rolex Submariner Date ref. 126613LB (2021) is a current-production Rolex “Bluesy.” The nickname comes from the watch’s signature pairing of a rich blue dial and matching blue bezel, paired with Yellow Rolesor in Oystersteel and 18-karat yellow gold. Introduced in 2020, the ref. 126613LB replaced the long-running ref. 116613LB and ushered in the latest generation of the Submariner collection. Among the most notable updates are the slightly larger 41mm case and slimmer lugs, giving the watch a more balanced, refined profile while preserving the famous Submariner aesthetic. Powering the watch is Rolex’s next-generation caliber 3235, featuring the efficient Chronergy escapement and an impressive 70-hour power reserve. Completing the package are the scratch-resistant blue Cerachrom bezel insert and Chromalight-filled hands and hour markers, which emit a long-lasting blue glow in low-light conditions.
