Reference Profile
The reference 126613LB belongs to the modern bi-metal Submariner lineage, combining Oystersteel and 18ct yellow gold in Rolex’s Rolesor configuration. Introduced alongside the redesigned Submariner case in 2020, it marked a transition to slightly increased case dimensions and revised proportions compared to the previous generation.
A blue dial and bezel configuration has historically been the most recognisable colourway within the two-tone Submariner range. The 126613LB continues this positioning as a more expressive and luxury-oriented alternative to all-steel Submariner references, while remaining a core model in Rolex’s current professional catalogue.
Movement Overview
The 126613LB is powered by the Rolex calibre 3235, an automatic mechanical movement used across much of Rolex’s modern range. The movement incorporates Rolex’s Chronergy escapement, designed to improve energy efficiency and resistance to magnetic fields.
Automatic calibre 3235 offers an approximate 70-hour power reserve and features a Parachrom hairspring along with Paraflex shock absorbers. It is regarded as robust and reliable, with service intervals extended compared to earlier-generation Rolex movements.
Functions & Complications
The watch displays hours, minutes, and seconds, with a date aperture positioned at 3 o’clock and magnified by a Cyclops lens. It features a unidirectional rotating dive bezel with a 60-minute scale for elapsed time measurement.
Water resistance is rated to 300 metres, supported by a screw-down crown with Rolex’s Triplock sealing system. The watch is fitted to an Oyster bracelet equipped with a Glidelock extension mechanism, allowing for fine adjustment without tools.
Buyer Considerations
The 126613LB typically appeals to buyers seeking a modern Rolex sports watch with a more pronounced visual presence than all-steel Submariner references. Its two-tone construction and blue colourway make it less understated but visually distinctive.
From an ownership perspective, yellow gold components tend to show wear more readily than steel, particularly on bracelet centre links and clasp surfaces. Market pricing is sensitive to condition and completeness, with full-set examples generally commanding a premium. Compared to steel Submariners, two-tone models often exhibit different demand characteristics, favouring longer-term ownership over short-term liquidity.
Comparisons & Aternatives
Rolex Submariner Date 116613LB
The direct predecessor to the 126613LB, produced from 2009 to 2020. It features a 40mm case, slimmer lugs, and is powered by the earlier calibre 3135. While visually similar, the 116613LB differs notably in proportions and movement architecture and is often preferred by buyers who favour the pre-2020 Submariner case design.
Rolex Submariner Date 126618LB
The full 18ct yellow gold counterpart to the 126613LB, sharing the same 41mm case design, blue dial, and bezel. The 126618LB offers a more overtly luxurious execution and carries a significantly higher market value, appealing to buyers prioritising precious metal content over versatility.
Omega Seamaster Diver 300M 210.20.42.20.03.001
A modern two-tone dive watch combining stainless steel and Sedna™ gold, produced as part of Omega’s contemporary Seamaster Diver 300M range. It features a blue ceramic bezel and dial, a helium escape valve, and is powered by the Master Chronometer calibre 8800, offering enhanced magnetic resistance. The Seamaster Diver 300M presents a technically focused alternative to the Submariner, with a more modern aesthetic and a distinct approach to dive-watch design.
