Rolex Submariner Steel/Yellow Gold — Blue Dial | Ref. 126613LB

Reference 126613LB is the current-generation two-tone Submariner, combining Oystersteel and 18ct yellow gold in what collectors commonly refer to as the "Bluesy" configuration — a pairing of blue dial and blue Cerachrom ceramic bezel insert with the warm contrast of yellow gold case and bracelet components. The 126613LB succeeded the 116613LB in 2020, growing the case to 41 mm and adopting the Calibre 3235 in place of the previous 3135. It is the definitive two-tone sports Rolex for a substantial segment of the market, recognisable at a distance yet technically up-to-date.

Calibre 3235 is the movement that defines the modern Submariner, offering a 70-hour power reserve, a Chronergy escapement, and a Rolex Parachrom hairspring for improved shock and magnetic resistance. The heavy new-style Oyster bracelet in the 126613LB is fitted with Oysterlock clasp and Glidelock extension system, providing secure fastening and fine length adjustment of approximately 5 mm without tools — a practical advancement over the earlier bracelet system. The Cerachrom ceramic bezel insert in blue is scratch-resistant and UV-stable, meaning the colour will remain consistent over decades of use.

The 126613LB occupies a well-understood position in the market: it carries more perceived warmth and luxury than the all-steel 126610LN while remaining significantly more accessible than the full yellow gold 126618LB. Brand new with box and papers, this reference enters the secondary market at a premium that reflects current production demand, and two-tone Submariner references have historically held value exceptionally well. For buyers who want a sports watch with genuine tool credentials and precious-metal presence in equal measure, the 126613LB is one of the most coherent answers in contemporary watchmaking.
