The two-tone Submariner Date in yellow gold and steel — Rolex's blue-on-blue combination at its most refined, with papers and like-new condition.
The Rolex Submariner Date 126613LB-0002 is the current-generation two-tone model, introduced in 2020 as the direct successor to the long-running 116613LB. At 41mm across the Oyster case — one millimetre larger than its predecessor — the shift in presence is subtle in hand but immediately legible on paper. The case and bracelet pair 904L stainless steel with 18-karat yellow gold across the bezel surround, crown, case flanks, and Oyster bracelet centre links. The blue Cerachrom ceramic bezel insert and matching blue Maxi dial produce the blue-on-blue combination that has defined this reference throughout its history. Applied gold hour markers, Mercedes hands with chromalight luminescence, and a date window at three o'clock with a Cyclops magnification lens complete the dial. Water resistance is rated to 300 metres. This example is dated 2021 and presents in like-new condition, accompanied by original Rolex papers.
The transition from 116613LB to 126613LB was not a cosmetic refresh. Rolex replaced the benchmark Calibre 3135 with the newer Calibre 3235, a certified Superlative Chronometer holding ±2 seconds per day. Power reserve extends to approximately 70 hours, up from roughly 48 in the outgoing movement. The Chronergy escapement, Paraflex shock absorbers, and a redesigned mainspring barrel contribute to the 3235's improved efficiency and long-term reliability. On a 2021 example, this movement is young and operating well within any reasonable service window.
The 126613LB-0002 consistently trades above its retail price on the secondary market. Two-tone Submariners occupy a distinct collector position: they appeal to the traditional diving-watch buyer and to a broader luxury audience for whom the yellow gold accent signals clear specification intent. The blue-dial, blue-bezel configuration is the higher-demand pairing within the two-tone lineup — it ages more gracefully than the yellow-dial variant and commands consistent attention at resale. This example arrives like-new, with its documentation, in the blue-on-blue pairing that turns heads without shouting. Two-tone Submariners have held value more steadily than many references through recent market corrections, supported by the inherent gold content and tight availability through the brand’s own retail network.
This piece is offered with papers but without the original box. The Rolex warranty card — now in the credit-card format introduced with the 126xxx generation — is the more consequential provenance document for authentication and future resale; the outer box has a negligible effect on transacted price. Buyers should confirm that the papers serial number matches the caseback engraving and that the documentation date aligns with the stated 2021 production year.
Like-new condition on a five-year-old reference suggests surfaces free of meaningful wear: no polishing artefacts on the case, no link stretch in the bracelet, crisp brushed flanks, and a Cerachrom bezel insert showing no chips or colour shift. Ceramic is highly resistant to everyday scratching, so a like-new grade here is credible — verify against close photographs at the lugs and clasp, where carry wear typically registers first. The Oyster bracelet on this reference uses Rolex's Glidelock micro-adjustment system, which allows half-millimetre sizing increments without tools and maintains a flush, clean clasp appearance at any setting.
The Submariner 126613LB-0002 is one of the most coherent arguments in modern production for a two-tone sport watch: genuine 300-metre dive credentials, a movement from the top of Rolex's current calibre family, and a gold-and-steel aesthetic that has sustained collector demand across multiple market cycles.
