Two Bezels, One Legacy
In the Rolex GMT-Master universe, two color combinations reign supreme: the Pepsi (blue and red) and the Coke (black and red). Both are nicknamed after soft drinks with matching color schemes, and both have decades of pilot and collector heritage. But they’re not interchangeable — each has a distinct personality, a different production history, and different implications for your collection.
The Pepsi: Where It All Started (1955)
The blue-and-red bezel debuted on the very first GMT-Master, Ref. 6542, in 1955. It was a functional design: blue represented nighttime hours (6 PM – 6 AM) and red represented daytime (6 AM – 6 PM), allowing pilots to quickly determine whether their home time zone was in daylight or darkness.
The Pepsi color scheme appeared on every subsequent GMT reference: 1675, 16750, 16710, and the current 126710BLRO. It has been in almost continuous production since 1955 — making it the longest-running bezel color in Rolex history.
Key Pepsi References
- Ref. 6542 (1955-1959): Bakelite bezel (fragile, extremely collectible). $50,000-$150,000.
- Ref. 1675 (1959-1980): Aluminum bezel, gilt or matte dial variants. The “Golden Era” Pepsi. $15,000-$40,000.
- Ref. 16710 (1989-2007): Sapphire crystal, aluminum bezel, Cal. 3185. Last steel Pepsi before the ceramic era. $12,000-$18,000.
- Ref. 126710BLRO (2018-present): Cerachrom ceramic bezel (first ever two-color ceramic). Cal. 3285, 70h reserve. Retail $10,900; secondary $15,000-$18,500.
The Coke: The Underrated Classic (1983)
The black-and-red “Coke” bezel first appeared on the Ref. 16760 “Fat Lady” — the first GMT-Master II with an independently adjustable hour hand. The Coke was positioned as the sportier, more understated alternative to the Pepsi. Where the Pepsi shouts “pilot’s watch,” the Coke whispers “traveler’s companion.”
The Coke was discontinued in 2007 when Rolex ended the 16710 reference, and has never been produced in ceramic. This makes it the rarest GMT color scheme in current Rolex — Pepsi, Batman, Root Beer, and Sprite all exist in Cerachrom, but the Coke does not.
Key Coke References
- Ref. 16760 (1983-1988): “Fat Lady” — first GMT-Master II. Thicker case, sapphire crystal. $15,000-$25,000.
- Ref. 16710 (1989-2007): Available in Coke (black/red), Pepsi (blue/red), and all-black bezel. This is the most common Coke reference. $12,000-$16,000.
- No ceramic version exists: Rolex has never produced a Cerachrom Coke bezel. This may change — the Sprite (green/black) debuted in 2022, suggesting Rolex is exploring new color combos.
Head-to-Head: Pepsi vs Coke
| Factor | Pepsi | Coke |
|---|---|---|
| First Appeared | 1955 | 1983 |
| Current Production | Yes (126710BLRO) | No (discontinued 2007) |
| Ceramic Bezel | Yes (Cerachrom) | No (aluminum only) |
| Heritage | Original GMT color, Pan Am pilots | GMT-Master II launch color |
| Vintage Market | $12,000-$150,000 | $12,000-$25,000 |
| Modern Market | $15,000-$18,500 | N/A (no modern equivalent) |
| Wearing Personality | Bold, iconic, conversation starter | Understated, sporty, subtle |
Investment Perspective
The Pepsi has historically appreciated more in absolute terms — the 126710BLRO’s secondary value has risen steadily since launch, and vintage Pepsi 1675s have doubled in the last decade. The Coke is a sleeper: 16710 Cokes have appreciated 40-60% since 2020 as collectors realize no ceramic replacement is coming anytime soon. If Rolex never makes a ceramic Coke, vintage aluminum Cokes could become significantly more valuable.
The Root Beer and Sprite: Where Do They Fit?
For completeness:
- Root Beer (brown/black): Current Ref. 126711CHNR on Rolesor (steel + Everose gold). ~$16,500 retail. The dressy GMT.
- Sprite (green/black): Ref. 126720VTNR (2022) with left-handed crown. $10,900 retail. The newest GMT colorway.
- Batman (blue/black): Ref. 126710BLNR. The modern classic. See our Pepsi vs Batman comparison.
Frequently Asked Questions
Will Rolex make a ceramic Coke bezel?
Nobody knows — Rolex doesn’t pre-announce. The Sprite’s 2022 debut proves Rolex is willing to create new Cerachrom color combinations. A ceramic Coke (black/red) seems technically feasible (black and red are both achievable in ceramic). If it happens, vintage aluminum Coke references might actually increase in value (as “original era” pieces), similar to how vintage aluminum Pepsi 16710s appreciated after the ceramic 126710BLRO launched.
Which is more versatile day-to-day?
The Coke. Black and red are more neutral than blue and red, pairing better with dark wardrobes, suits, and formal settings. The Pepsi’s blue pops more and reads as “sportier” — excellent for casual and business-casual, but occasionally loud in conservative environments.
Why is the Coke called “Coke”?
The black-and-red color scheme matches Coca-Cola’s logo and branding. The nickname emerged in collector communities in the 1990s-2000s and stuck. Neither Rolex nor Coca-Cola endorses or uses the nickname officially.
