Rolex Submariner 116613LB: Why the Blue Dial Defines the Reference
The Rolex Submariner 116613LB sits at a useful fault line in the model’s history. Introduced in 2009, it combined the familiar two-tone Submariner formula with a blue Cerachrom bezel and the broad-shouldered 40 mm “Super Case.” It was the first yellow Rolesor Submariner to receive a ceramic bezel, but it retained the proven calibre 3135 architecture that had defined the preceding generation. For collectors, that makes the reference more than a colourful alternative: it is the point where the modern ceramic Submariner began without yet becoming the current watch.
The blue is not a minor detail
The “LB” identity depends on the relationship between three surfaces: the blue bezel, the blue dial and the yellow-gold centre links. Ceramic changed the bezel from a consumable component into a harder, more colour-stable visual frame. The dial, meanwhile, can look restrained indoors and much brighter in direct light. That range is central to the watch’s appeal, but it also means photographs are a poor substitute for checking the actual dial and bezel together.
The 40 mm case is nominally compact by current standards, yet the squared crown guards, wider lugs and substantial bracelet give it more wrist presence than the diameter suggests. Buyers who want the visual impact of the later 41 mm reference may find it here; those expecting the taper and lightness of an older five-digit Submariner should not.
A transitional reference, not a smaller 126613LB
The 116613LB was replaced in 2020 by the 41 mm 126613LB. The successor introduced calibre 3235, a power reserve of roughly 70 hours and revised proportions with narrower-looking lugs. The 116613LB uses calibre 3135, offers approximately 48 hours of reserve and has the denser silhouette of the earlier ceramic generation. Both provide 300 metres of water resistance and a Glidelock-equipped Oyster bracelet, but they do not feel like the same watch in different sizes.
That distinction matters when comparing prices or condition. A lower asking price than a current-generation example does not by itself make the 116613LB the better purchase. The older reference earns its place through its proportions, mature 3135 movement and unmistakable blue-and-gold expression.
Where condition tells the story
Two-tone construction makes wear easy to read. Polished yellow-gold centre links collect marks quickly, while repeated refinishing can soften the transition between brushed steel and polished gold. Examine the bezel teeth, lug geometry, crown guards and clasp edges rather than relying on an overall impression of shine. Bracelet articulation should be even, and the Glidelock mechanism should move securely through its positions.
The dial deserves equal scrutiny. Confirm that its printing, hands and luminous plots are coherent, and compare the reference and serial details with the watch’s documentation. A pressure test and service record matter more to practical ownership than a complete accessory set alone. Neither paperwork nor a polished exterior proves mechanical condition.
The collector’s decision
The 116613LB is strongest when bought for what it is: a first-generation ceramic Rolesor Submariner with the compact mechanics of calibre 3135 and an intentionally extrovert palette. It is not the restrained choice in the Submariner family, and it should not be assessed as one.
Prioritise an honest case, a consistent dial-and-bezel presentation, a sound bracelet and evidence of proper water-resistance maintenance. Then decide whether the blockier 40 mm proportions suit your wrist better than the more refined 41 mm successor. Get those points right and the blue 116613LB remains one of the clearest expressions of Rolex’s transitional ceramic era.
