About the Rolex Submariner 126618LB

The Rolex Submariner 126618LB is the solid 18k yellow gold Submariner Date with a royal blue sunburst dial and matching blue ceramic bezel. Rolex introduced it in 2020 as part of the generation-wide Submariner refresh that moved the case to 41mm and brought in the Caliber 3235 movement. WatchGuys carries pre-owned and unworn 126618LB watches, each authenticated in-house and backed by a 2-year warranty. Below we cover what the 126618LB is, the details that define it, what it costs, and how it compares to the references around it.

What Is the Rolex 126618LB?

The 126618LB is a Rolex Submariner Date produced from 2020 to the present, cased entirely in solid 18k yellow gold. The case, bezel, crown, and every link of the Oyster bracelet are solid gold rather than plated, which is what separates it from the two-tone Rolesor references and drives the bulk of its price. It pairs a blue sunburst dial, with gold-surround Chromalight hour markers and gold Mercedes hands, against a blue Cerachrom ceramic bezel with gold-coated graduations. Rolex's internal suffix "LB" stands for Lunette Bleue, French for blue bezel. Inside is the Caliber 3235, running at 28,800 vibrations per hour with roughly 70 hours of power reserve and Superlative Chronometer certification. The bracelet uses the Glidelock clasp, and water resistance is 300 meters.

One detail defines how the 126618LB reads on the wrist: the dial is a sunburst finish rather than the flat lacquer used on the black-dial 126618LN. The brushed radial texture catches light differently as the wrist moves, shifting the blue from near-navy in shadow to a bright royal tone in direct light. Against the warm yellow gold, that shifting contrast is the reason many buyers choose the LB over its black-dial sibling.

Rolex 126618LB Price

Pre-owned and unworn Rolex 126618LB watches at WatchGuys typically range from $36,000 to $46,000 or more. Where a specific piece lands depends on production year, condition, and whether it includes the original box and papers. Unworn full-set examples command the upper end. Because the case and bracelet are solid gold, the intrinsic metal content puts a floor under this reference that the steel Submariners do not have, which has historically helped it hold value through softer market cycles.

126618LB vs. 126618LN vs. 116618LB

The 126618LB has two natural comparisons. The Rolex 126618LN is its sibling in the current Rolex 126618 family, mechanically and dimensionally identical but fitted with a black lacquer dial and black bezel instead of blue. The LN is the more restrained of the pair and the easier one to wear with a suit; the LB is the statement version. The Rolex 116618LB is the direct predecessor, produced from 2008 to 2020 with a 40mm case, the Caliber 3135, and a 48-hour power reserve rather than 70. Buyers who prefer more compact proportions or want a discontinued reference gravitate toward the 116618 generation. If solid gold is more watch than you want, the two-tone Rolex Bluesy offers the same blue-on-blue formula in Rolesor at a fraction of the price, while the white gold Submariner references pair blue with a far more discreet case metal.

Common Questions

Rolex 126618LB FAQ

• What Does the "LB" in 126618LB Mean?

  LB stands for Lunette Bleue, French for blue bezel. Rolex uses the suffix to distinguish the blue dial and blue bezel configuration from the 126618LN, where LN stands for Lunette Noire, or black bezel. Both are the same solid gold reference, and the suffix is the only thing separating them on paper.

• Is the Rolex 126618LB Solid Gold or Plated?

  It is solid 18k yellow gold throughout. The case, bezel, crown, and every link of the Oyster bracelet are solid gold rather than plated or gold-capped. That solid metal content is why the 126618LB weighs noticeably more than the steel Submariner and why it carries a substantially higher price.

• How Much Does a Rolex 126618LB Cost?

  Pre-owned and unworn 126618LB prices at WatchGuys typically range from $36,000 to $46,000 or more. Production year, condition, and whether the original box and papers are included all affect where a piece lands. Contact our team for current pricing on a specific 126618LB in our inventory.

• What Is the Difference Between the 126618LB and 126618LN?

  The case, movement, size, and bracelet are identical. The difference is color. The 126618LB has a blue sunburst dial with a blue bezel, and the 126618LN has a black lacquer dial with a black bezel. The LB is the bolder visual statement against the gold, while the LN is the more understated of the two.

• Is the 126618LB the Same as the Rolex Bluesy?

  No. The Bluesy nickname refers to the two-tone Rolesor Submariner Date, which combines Oystersteel with 18k yellow gold and carries a blue dial and blue bezel. The 126618LB shares the blue-on-blue look but is cased entirely in solid 18k yellow gold, with no steel anywhere in the watch. That difference in material puts the two at very different price points.

• How Does the 126618LB Compare to the 116618LB?

  The 126618LB replaced the 116618LB in 2020. The case grew from 40mm to 41mm with slimmer lugs and crown guards, and the movement was upgraded from the Caliber 3135 to the 3235, raising the power reserve from 48 hours to about 70. Both are solid 18k yellow gold with a blue dial and blue Cerachrom bezel.
