Introduction

The Rolex GMT-Master II reference 126710BLRO, universally known as the 'Pepsi,' is more than a watch—it’s a statement. Since its debut in 2018, this iteration has redefined the travel watch category with a ceramic bezel in red and blue, a Jubilee bracelet, and the in-house Caliber 3285 movement. For the sophisticated young collector, it bridges heritage and modernity without sacrificing daily wearability.

On the wrist, the 126710BLRO is a study in balance. The 40mm case sits comfortably on a range of wrist sizes, while the 48mm lug-to-lug ensures it doesn’t overhang. The Jubilee bracelet, once considered too dressy for a tool watch, now feels like the perfect companion for a watch that can go from a boardroom to a beach. The red and blue bezel is instantly recognizable, yet the matte ceramic finish keeps it from being flashy.

This review focuses on how the Pepsi performs in real life—not just on a spec sheet. We’ll examine lug-to-lug comfort, legibility in various lighting, and what survives a week of travel, work, and play. If you’re considering adding this reference to your collection, read on for an honest, wear-focused assessment.

Manufacture History

Rolex was founded by Hans Wilsdorf in London in 1905, moving to Geneva in 1919. The GMT-Master line was introduced in 1954 for Pan American World Airways pilots, featuring a 24-hour bezel and an additional hand to track a second time zone. The 126710BLRO continues this legacy with modern materials and movements.

Movement

The Caliber 3285 is an automatic movement with 70 hours of power reserve, beating at 28,800 vph. It features 31 jewels, a date complication, and a GMT function with an independently adjustable 24-hour hand. The movement is COSC-certified and entirely in-house. Rolex’s Chronergy escapement improves efficiency, while the Parachrom hairspring offers resistance to magnetic fields and temperature variations. Finishing is industrial but robust, with perlage and Geneva stripes visible through the sapphire caseback.

Wrist Feel

The 126710BLRO wears remarkably well for a 40mm tool watch. The Jubilee bracelet is supple and conforms to the wrist without pulling hair, thanks to its five-piece links. At 12.5mm thick, it slides under a dress shirt cuff with minimal resistance, though the clasp—while secure—adds a bit of bulk. The 48mm lug-to-lug keeps the watch centered on average wrists (6.5 to 7.5 inches), and the 100g weight (with full links) feels substantial without being fatiguing.

During a week of wear, the Pepsi proved comfortable for everything from typing at a desk to hiking in humid conditions. The Easylink extension allows quick adjustment for temperature changes, and the Oysterlock clasp never accidentally opened. The only minor complaint is the clasp’s sharp edges on the underside, which can dig into the wrist during prolonged typing. Overall, it’s a watch you forget you’re wearing—until you glance at the bezel.

Accuracy

In real-world testing over two weeks, the Caliber 3285 averaged +1.2 seconds per day, well within Rolex’s -2/+2 second Superlative Chronometer certification. The 70-hour power reserve held steady, and the movement maintained accuracy even when partially wound. Day-to-day, you can expect to set it once a week at most.

Occasions

The Pepsi is remarkably versatile. It works with a suit for formal events, pairs with a polo for daily office wear, and handles swimming or hiking thanks to 100m water resistance. The GMT function makes it ideal for travel, and the Jubilee bracelet adds a touch of elegance for dressier occasions.

Wrist Presence

4.5/5 – The red and blue bezel is instantly recognizable, but the matte ceramic finish and Jubilee bracelet keep it from being ostentatious. It commands attention without screaming for it.

Rolex recommends service every 10 years, though many owners opt for a 5-year check. Authorized service centers only; cost approximately $800 for a full overhaul. The movement is robust, but regular maintenance ensures longevity.

$10,700 (retail) to $20,000 (pre-owned). At retail, it’s a bargain; on the secondary market, you pay for instant availability. For trust-fund-baby buyers, the Pepsi is a must-have status symbol that also holds value.
