Rolex GMT-Master II Pepsi: The Evolution of MK1, MK2, and MK3 Bezels

Imagine pulling a watch from your pocket and catching the light on the bezel. Red. Blue. Red. Blue. A rhythm of colors that has followed travelers across continents since 1954. This is the Rolex GMT-Master II “Pepsi” — and since Rolex revived this iconic color combination in 2018, three distinct generations have emerged, each with its own character.

The Return of a Legend

The very first Rolex GMT appeared in 1954 with a blue-red bezel. Airlines recognized its utility: two colors, two time zones on your wrist. Pilots could tell at a glance where they were and where they were heading.

The Pepsi remained a legend for decades, until Rolex discontinued it in 2005. Then, in 2018, Rolex brought it back — reference 126710BLRO — and the watch world erupted.

MK1: The First Impression — Soft and Subtle

The MK1 bezel feels like a cautious return. The red isn’t loud. Some collectors describe it as “washed out” — an elegant, almost vintage appearance. For collectors who value subtlety, MK1 is a dream.

MK2: The Deepening — More Pronounced

Late 2018 brought MK2. The red became deeper. Richer. More vital. MK2 feels like Rolex said: “Let’s push this further.” Under daylight, MK2 becomes a statement bezel.

For many collectors, MK2 is the sweet spot — not too cautious, not too aggressive.

MK3: Back to the 1950s — Vivid and Authentic

Around mid-2019, Rolex introduced MK3. This is clearly an attempt to get closer to the 1954 original. The red is more saturated. Bold, even. This isn’t a subtle bezel anymore — it’s one that demands attention.

For purists who want the vintage Pepsi experience in modern form, MK3 is the goal.

The Timeline

MK1: 2018
MK2: Late 2018 to early 2019
MK3: Mid-2019 to present

How to Tell the Difference

• Color intensity: MK1 is muted. MK2 is medium. MK3 is vivid.
• Light reflection: MK1 absorbs light, MK2 balances it, MK3 radiates back.
• Production year: Serial numbers tell the story.

The Collector’s Dilemma

Which do you choose? The answer depends on your personality. Subtlety? MK1. Balance? MK2. Purist? MK3.
