Rolex returns with this stainless-steel option that’s enhanced its case and inner movement. This watch was originally introduced back in 1955 and would follow an increase in popularity with the expansion of intercontinental travel that occurred in the latter half of the 20th century, due to its GMT capabilities and the now iconic “Pepsi bezel” with a red-half for daylight hours and blue-half for night-time hours.

The 40mm case is made of stainless-steel with a solid case back. Mounted to the watch is a bi-directional rotatable bezel with the iconic 24-hour graduated two-color Cerachrom insert in red and blue, commonly referred to as the “Pepsi” due to its color scheme.

The lugs and sides of the Oyster case have been slightly redesigned for this new edition. Topped with a scratch-resistant sapphire crystal and featuring a screw-down crown with a “Triplock” triple waterproofness system, which assists with water-resistance on this watch reaching up to 100 meters (330 feet)

But, the big novelty here is a new-generation of mechanical movement with 10 patents housed inside this Rolex case, which sets new standards of performance for the core characteristics of a watch movement: precision, power reserve, reliability, resistance to shocks and magnetism, as well as the ease and convenience of its adjustment. The criteria for precision of the new caliber 3255 is twice as exacting as those offered by an officially certified chronometer with a 15% gain in efficiency.

It does so by incorporating the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. This material is made of nickel-phosphorus, which is insensitive to magnetic interference. While the oscillator that functions as the true heart of the watch, has been optimized with a blue Parachrom hairspring, which is also up to 10 times more precise than a traditional hairspring in case of shocks.

The previous GMT version was equipped with a self-winding mechanical movement, caliber 3186 with 31 jewels and 28,800 Vph. It was a certified Swiss chronometer (COSC) but these new Rolex.

Time is exhibited on a black dial with 18k white gold applied hour index markers in round, rectangular and a triangular shape at the 12 o’clock position. Circling the dial are also white printed minute index markers. The central hands, hour index markers and arrow-tip of the red GMT hand, have all undergone a blue-toned luminescent coating for an enhanced legibility. There is also a date aperture at the 3 o’clock position with a magnifying cyclops lens.

Rolex GMT-Master II Pepsi

This “Rolex GMT-Master II Pepsi” (Ref#: 126710BLRO) is powered by a self-winding mechanical movement, caliber 3285 with 28,800 Vph. Power reserve on this watch can last up to 72 hours (3 days) when fully wound, thanks to a new barrel architecture and the superior efficiency of the caliber 3285 escapement. Meaning this timepiece can easily continue to run from Friday evening till Monday afternoon, even if it’s worn or wound.


Mounted to the watch is a stainless-steel five-link Jubilee bracelet, secured to the wrist by a stainless-steel Oysterlock. This kind of bracelet hasn’t been seen on a GMT-Master model, since the vintage years and currently could only be seen on Datejust models.
