Rolex Submariner Date 126613LB Watch Review

For many enthusiasts, the Submariner isn’t just a watch; it’s the watch. It’s the blueprint against which all other dive watches are measured. But within this legendary collection, some references stand out for their unique character and bold presence. The Rolex Submariner Date 126613LB, often nicknamed the “Bluesy,” is one such timepiece. It takes a classic tool watch formula and infuses it with a dose of undeniable luxury. Having spent some significant time with this watch, I’m here to share my insights on why this two-tone marvel is more than just a flashy diver.

The moment you unbox the 126613LB, it makes an impression. The combination of Oystersteel and 18k yellow gold is quintessentially Rolex, a blend of ruggedness and opulence that the brand has perfected. The 41mm case, a contemporary update from the previous 40mm, is virtually imperceptible on the wrist but gives the dial and bezel a slightly more modern presence. It retains the iconic Submariner profile—robust, purposeful, and instantly recognizable.

The star of the show, without a doubt, is the stunning blue Cerachrom bezel and matching sunburst dial. Under different lighting conditions, the blue shifts from a deep, almost navy hue to a vibrant, brilliant royal blue. The bezel’s ceramic construction means this colour will remain scratch-resistant and fade-free for a lifetime. Paired with the warm glow of the yellow gold, the effect is breathtaking. It’s sporty, yes, but with a level of elegance that few dive watches can achieve.

Let’s break down the components that make this watch so special.

• The Case & Bracelet: The construction is top-tier. The Oystersteel provides a cool, sharp contrast to the rich yellow gold of the center links and bezel. The Oyster bracelet is a masterpiece of comfort and durability, with the iconic solid links and Oysterclasp featuring the Rolex Glidelock extension system. This allows for tool-free, fine adjustments over approximately 15mm, perfect for wearing over a wetsuit or simply adjusting for comfort on a hot day.

• The Dial & Legibility: The blue sunburst dial is a chameleon. In direct light, it explodes with texture and depth, while in lower light, it becomes a deep, serene backdrop for the highly legible Chromalight display. The hands and hour markers, filled with Rolex’s proprietary luminescent material, glow a persistent blue in the dark—a subtle nod to the watch’s colour scheme even in total darkness. The date at 3 o’clock, magnified by the Cyclops lens, is a signature Rolex feature and remains perfectly crisp.

• The Movement: Caliber 3235: Beating inside this robust case is Rolex’s in-house Caliber 3235. This is a true workhorse movement and a significant step up from its predecessors. It incorporates Rolex’s patented Chronergy escapement for improved efficiency, along with paramagnetic blue Parachrom hairspring. The most talked-about feature, however, is its 70-hour power reserve. This is a game-changer for daily wear. You can take the watch off on a Friday evening and it will still be ticking when you pick it up on Monday morning, without needing a wind.

One might assume a two-tone, blue-and-gold watch is challenging to style. I found the opposite to be true. The 126613LB is surprisingly versatile. It pairs effortlessly with a casual weekend outfit—a t-shirt and jeans—adding a touch of sophistication without looking out of place. Conversely, it slides just as easily under the cuff of a dress shirt for more formal occasions, where the gold elements provide a perfect complement to other accessories.

The 300-meter water resistance is, for most of us, overkill, but it speaks to the watch’s inherent capability. This is a true tool watch at heart, just one that’s been dressed in its Sunday best.
