Rolex GMT-Master II "Pepsi"

Introduction

The Rolex GMT-Master II reference 126710BLRO, better known as the 'Pepsi,' is the watch that defined a decade. When Rolex reintroduced the red-and-blue ceramic bezel in 2018 on a Jubilee bracelet, the hype machine went into overdrive. It wasn't just a reissue—it was a cultural reset. From NBA players courtside to crypto founders in Davos, the Pepsi became the unofficial badge of the modern jet-setter. But does the watch live up to the legend? After months on the wrist and deep dives into the secondary market, here’s the unvarnished truth.

This isn’t just a tool watch. It’s a statement piece that bridges the gap between aviation heritage and streetwear credibility. The 126710BLRO is the GMT that collectors fight over, influencers flex, and auction houses love. Yet beneath the hype lies a serious piece of horology—a 40mm stainless steel case, a ceramic bezel that won’t fade, and a movement that’s genuinely impressive. Let’s break down what makes this watch tick, and why it’s still the king of the travel watch category.

Manufacture History

Rolex was founded in London in 1905 by Hans Wilsdorf and Alfred Davis, moving to Switzerland in 1919. The brand pioneered the first waterproof wristwatch (Oyster, 1926) and the first automatic date watch. The GMT-Master line debuted in 1954 for Pan Am pilots, with the iconic red-and-blue 'Pepsi' bezel introduced in 1955 on the ref. 6542. The 126710BLRO continues that legacy with a modern ceramic insert and the latest movement technology.

Movement: Caliber 3285

The heart of the 126710BLRO is the in-house Caliber 3285, an automatic movement with 70 hours of power reserve and a frequency of 28,800 vph. It features Rolex’s patented Chronergy escapement, a paramagnetic blue Parachrom hairspring, and a ball bearing rotor for efficient winding. The movement is COSC certified and offers hacking seconds, a quick-set date, and an independently adjustable 24-hour hand for tracking a second time zone. Finishing is industrial but robust—perlage on the bridges and a sandblasted mainplate, built for reliability over decoration.

Specifications

• Case diameter: 40mm
• Case thickness: 12.5mm
• Lug-to-lug: 48mm
• Case material: Stainless steel (904L Oystersteel)

Wrist Feel

The 40mm case feels compact and balanced—surprisingly light for a steel sports watch. The Jubilee bracelet drapes beautifully, with the five-piece links offering a vintage charm that the Oyster bracelet can’t match. At 12.5mm thick, it slips under a dress shirt cuff without protest, though the bezel’s knurling is grippy enough for gloved use. The 48mm lug-to-lug ensures a flat sit on most wrists, even those under 6.5 inches. The only quibble: the clasp’s Easylink extension is fiddly to adjust on the fly, but once set, the watch stays put.

Accuracy

In real-world wear, the Caliber 3285 consistently runs within +2 to +4 seconds per day—well within COSC specs. After a week of mixed desk diving and active travel, I observed an average of +2.3 spd. The 70-hour power reserve means you can take it off Friday evening and it’s still running Monday morning. No complaints on precision.

Occasions

The Pepsi is versatile enough for formal events (paired with a suit), sporty weekends (on rubber or NATO strap), daily wear, travel, and even dressier occasions. Its 100m water resistance and screw-down crown make it pool-friendly, while the GMT function is a godsend for frequent flyers.

Wrist Presence

5/5 – The Pepsi bezel is an instant conversation starter. The red-and-blue ceramic insert pops against any outfit, and the Jubilee bracelet catches light like a chainmail. On the wrist, it commands attention without screaming—a masterclass in restrained boldness.

Reference Variants

The 126710BLRO is available on Jubilee (standard) and Oyster bracelet (introduced 2021). Both use the same case and movement. The Oyster version is slightly sportier and less dressy, but both are equally collectible.

Family References

Predecessors include the ref. 1675 (aluminum bezel), 16750, 16760 (first GMT-Master II), 16710, and 116710BLRO (first ceramic bezel on GMT, but with black dial and green GMT hand). The 126710BLRO is the current production model.

Other Models by Rolex

Notable siblings include the Submariner 126610LV (green bezel), Daytona 116500LN (black ceramic), and Explorer II 226570 (white dial, orange GMT hand).

Similar Watches

Tudor Black Bay GMT – Affordable sibling with similar GMT functionality and a red-and-blue bezel. Omega Seamaster Planet Ocean GMT – Larger, more robust GMT diver with a ceramic bezel and co-axial movement. Grand Seiko SBGE253 – Spring Drive GMT with a 72-hour power reserve and a more understated aesthetic.

Homages

Seiko SRPE53K1 ($250) – A budget-friendly GMT-style watch with a red-and-blue bezel, though true GMT movement is absent. Steinhart GMT 39 Pepsi ($450) – A faithful homage with a 39mm case, ceramic bezel, and ETA movement—great value for the Pepsi look.

Investment Value

MSRP is $10,700, but retail availability is nearly impossible. Pre-owned prices range from $15,000 to $25,000 depending on condition and box/papers. The trend is appreciating, though the secondary market has softened slightly from 2022 peaks. Auction history: A 126710BLRO sold at Phillips in 2023 for $22,800; a 2019 example fetched $19,500 at Christie’s in 2024. The reference consistently outperforms MSRP at auction. If you can get it at retail, buy and hold.

Service Interval

Rolex recommends service every 5-10 years. Authorized service centers cost ~$800 for a full overhaul, but independent watchmakers can do it for less, though parts availability is restricted.

Pros and Cons

Pros: Iconic red-and-blue ceramic bezel with scratch resistance; superb Caliber 3285 movement with 70-hour power reserve; comfortable Jubilee bracelet with Easylink adjustment; strong investment potential and cultural cachet.

Cons: Extremely difficult to find at retail—long waitlists; premium on secondary market is steep; no quick-set hour hand for true traveler GMT (uses 24-hour hand adjustment); clasp can feel a bit dated compared to competitors' micro-adjust systems.

Final Verdict

The Rolex GMT-Master II 'Pepsi' 126710BLRO is more than a watch—it’s a cultural artifact. It delivers on performance, heritage, and wrist presence, even if the hype inflates its price. For the collector who values both horology and status, it’s a must-have. Just be prepared to play the game—or pay the premium.
