Among two-tone dive watches, the Rolex Submariner Date 126613LB – often called the “Bluesy”, holds a special place. With its vivid royal blue dial, yellow gold details, and stainless steel construction, it brings together the toughness of a tool watch with the presence of something more eye-catching. It’s sporty and dressy at the same time, with just enough flash to turn heads.

Let’s break down what makes the 126613LB such a standout in the Submariner family, from its history and case profile to how it wears on the wrist.

Where the Rolex Submariner Date 126613LB Comes From 

The Submariner line debuted in 1953, setting the standard for what a dive watch should be. But the “Bluesy” didn’t arrive until the early 1980s, when Rolex began offering steel and yellow gold combinations in the Submariner Date lineup. The blue-and-gold look quickly became one of the most recognizable colorways, gaining fans who wanted the toughness of a Submariner with a bit more color and shine. 

The current version, reference 126613LB, was introduced in 2020. It replaced the previous 116613LB and brought with it a few subtle upgrades: a slightly larger 41mm case (up from 40mm), thinner lugs for better balance, and an upgraded movement with a longer power reserve. This version continues the Submariner tradition while updating it just enough to feel current.

Case & Bracelet: Built for Depth, Styled for Versatility 

The Submariner Date 126613LB features a 41mm Oystersteel case paired with an 18k yellow gold unidirectional bezel and screw-down crown. Rolex calls this two-tone blend “Rolesor”, and it’s been part of their lineup since the 1930s. 

In this model, the center links of the bracelet, crown, and bezel all feature yellow gold, while the rest of the watch is crafted from corrosion-resistant Oystersteel.

The mix of finishes matters here: the case sides and bracelet center links are high-polished, while the top surfaces and outer links have a brushed finish. This helps soften the visual impact while still letting the gold details pop when light hits the watch at certain angles.

The Triplock crown system, solid caseback, and scratch-resistant sapphire crystal all work together to give the watch 300 meters of water resistance – well beyond most everyday needs.

Attached is the classic three-link Oyster bracelet, which tapers slightly and closes with a solid folding clasp. The Glidelock extension system lets you adjust the fit in 2mm increments up to 20mm without using tools, making it easy to find the perfect fit whether you’re wearing it over a wetsuit or just adjusting for a humid day.

Dial Design: That Signature Blue 

The dial is where the “Bluesy” nickname really earns its place. The sunburst royal blue dial shifts tone depending on the light – ranging from a deep navy to a bright cobalt glow. It’s vibrant, but not overly loud.

The hour markers are filled with Rolex’s Chromalight lume, which glows blue in the dark and remains visible for long periods. The hands and the bezel marker are also lume-filled and made of 18k yellow gold to match the hour marker surrounds.

At 3 o’clock is the date window, covered by a Cyclops lens that magnifies the date for quick reading. The dial is kept simple and uncluttered, with white text and the signature Submariner depth rating.

This balance of rich color and functional clarity makes the dial a standout while still keeping it readable underwater or in low light.

Movement and Functions: Built to Dive, Ready for Daily Life 

At the heart of the Submariner Date 126613LB is the Rolex Caliber 3235 – a self-winding mechanical movement known for its durability and accuracy. It delivers a 70-hour power reserve and maintains Superlative Chronometer certification, which means it’s tested to perform within –2 to +2 seconds per day after casing.

Here’s how the crown and bezel work together with the movement:

• Crown Position 0 (screwed down): Maintains water resistance up to 300 meters (1,000 feet).
• Crown Position 1 (unscrewed): Turn clockwise to manually wind the movement.
• Crown Position 2 (pulled out halfway): Quickset the date without moving the hour or minute hands.
• Crown Position 3 (fully pulled): Set the time precisely. The seconds hand stops, letting you sync the time exactly.

Bezel Function 

The 18k yellow gold bezel features a unidirectional rotating design with a 60-minute Cerachrom insert in blue ceramic. This insert is made from highly scratch-resistant ceramic and has engraved numerals and markers coated in gold.

Divers (or even frequent flyers or chefs) can align the zero marker with the minute hand to measure elapsed time. Since it only turns counterclockwise, there’s no risk of accidentally extending dive time—a safety feature originally designed for underwater use.

Even if you’re not diving, the bezel becomes a practical timing tool for parking meters, workout intervals, or timing your espresso.

Water Resistance 

This Submariner model is water-resistant to 300 meters (1,000 feet), thanks to several protective components:

• The Triplock crown uses a triple gasket system to seal out moisture.
• The monobloc middle case, made from solid Oystersteel, gives the structure extra strength.
• The screw-down caseback and tightly fitted sapphire crystal complete the barrier, keeping the movement safe from pressure, dust, and water.

These features ensure that whether you’re diving, swimming, or just navigating daily life, the watch is always protected.

On the Wrist: Comfort Meets Statement 

Despite the 41mm case size, the Submariner Date 126613LB wears comfortably even on mid-sized wrists. The thinner lugs make the profile feel more balanced, and the taper of the bracelet helps it sit securely without sliding around.

It’s not a small watch, and the yellow gold does add visual weight – but it doesn’t feel heavy on the wrist. The Glidelock system lets you make quick sizing adjustments during the day, which is especially helpful in hot or cold weather.

This is a watch that feels comfortable for everyday use, whether you’re dressed up, at the beach, or heading out for the evening.

Final Thoughts: Is the 126613LB Right for You? 

The Submariner Date 126613LB, or “Bluesy”, is one of those watches that’s instantly recognizable. It stands out in a sea of dive watches with its two-tone construction and blue dial but still holds on to the features that made the Submariner a classic: ruggedness, water resistance, and reliable timekeeping.

If you’re a collector looking for a Submariner with a bit more personality, this version brings just enough flair. For someone stepping into their first two-tone Rolex, it offers the familiarity of a steel sports watch with extra warmth and color.

It’s not about blending in. It’s about having something that works anywhere – on the wrist and in the conversation.
