The GMT-Master II is arguably Rolex's most collector-interesting current reference. Where the Submariner offers one meaningful configuration choice — black bezel or green bezel — the GMT-Master II has six current steel and precious metal configurations, each with a distinct two-color bezel, a colloquial nickname, and its own secondary market premium. Add the functional GMT complication that the Submariner lacks, and you have a watch with genuine collecting depth at every price point.
This guide covers every current GMT-Master II reference, explains the nickname system, identifies which discontinued variants are worth knowing, and offers a direct comparison to the Submariner for buyers considering both.
Understanding the GMT Function
The GMT complication tracks a second time zone using a 24-hour hand that completes one rotation per day, read against a bidirectional 24-hour bezel. The older GMT-Master used a bidirectional bezel where setting the GMT required spinning both the bezel and the local time simultaneously — functional but cumbersome.
The GMT-Master II introduced independently adjustable local hour hand, allowing the wearer to advance or retard the local hour hand in one-hour increments while the minute and second hands continue running. This means landing in a new time zone and adjusting local time takes four or five clicks of the crown — the home time zone never moves, the GMT hand never moves, and the operation is done in seconds.
For frequent travelers, this is genuinely useful. The two-timezone display is legible at a glance: the 24-hour bezel color (red = daytime, blue = nighttime on the Pepsi) tells you whether your home city is in day or night without any mental arithmetic. The complication is not decorative — it was designed to solve a real problem for Pan American Airways pilots in 1955, and it solves it as cleanly today.

The Nickname System Explained
The GMT-Master nicknames originated with collectors and press writers in the 1950s and 1960s and have since been adopted universally — including, informally, by Rolex dealers and authorized service centers.
Pepsi is the oldest and most iconic nickname, applied to the red/blue bezel configuration. The first GMT-Master (Ref. 6542) delivered to Pan American Airlines in 1955 had a red/blue Bakelite bezel, and the color scheme has been inseparable from the model ever since. The ceramic Pepsi bezel on the current 126710BLRO is technically more difficult to produce than a single-color ceramic — hence the limited supply and significant secondary market premium.
Batman — the black/blue bezel — earned its name from a 2013 baselworld introduction. The combination of black (representing night) and blue (representing day) was quickly compared to the caped crusader's color palette. The Batman is considered the most versatile of the GMT lineup: dark enough to read as formal, interesting enough to satisfy collectors.
Root Beer earned its name from the brown/black bezel's warm tones, which collectors likened to the color of the American soft drink. The current steel Root Beer (126711CHNR) pairs the brown/black bezel with the five-link Jubilee bracelet and a warm brown dial — a combination with strong collector appeal.
Sprite is the newest nickname, applied to the 2022-introduced green/black Jubilee reference 126713GRNR. The green/black bezel combined with a green dial and Jubilee bracelet has proven immediately popular, with secondary market prices moving above the Pepsi in some conditions.
Key Discontinued References Worth Knowing
The 116710BLNR (Batman, steel Oyster, pre-2019) is the previous-generation Batman. It uses the older Calibre 3186 movement rather than the current 3285. Secondary market prices run $12,000–$16,000 — slightly below the current 126710BLNR, more available, and a legitimate collecting target for buyers who want the Batman aesthetic at a slight discount. The bracelet is the older Oyster without the Glidelock extension.
The 16710 BLRO (Pepsi with aluminum bezel) is the pre-ceramic Pepsi. Aluminum bezels fade, scratch, and age — this is considered a feature by collectors, not a defect. A faded "tropical" aluminum Pepsi bezel on a pristine case is a highly sought collector piece. Prices run $8,000–$14,000 depending on dial, bezel condition, and whether the watch is a "Fat Lady" (sapphire crystal era, 1988–1990) or later variant.
GMT vs Submariner: Which to Buy
The GMT-Master II has a functional advantage over the Submariner: it tracks two time zones simultaneously without mental arithmetic. If you travel internationally with any regularity, this is genuinely useful and not a trivial distinction.
The bezel variety creates more collecting depth. The Submariner offers essentially two meaningful configurations at the steel level (black bezel, green bezel). The GMT offers four, each with distinct secondary market behavior and collector communities. For buyers who enjoy the reference-following side of watch collecting, the GMT is more interesting.
The Submariner remains cleaner and more versatile on the wrist. A black Submariner disappears under a suit sleeve. A Pepsi GMT announces itself. Neither is wrong — they serve different buyers. For buyers who want one serious Rolex and will wear it in formal contexts as often as casual ones, the Submariner is easier to live with. For buyers who want to maximize collecting interest and secondary market dynamics, the GMT is the stronger choice.
How to Buy a Pre-Owned GMT-Master II
- Verify bezel ceramic integrity. Two-color ceramic bezels are more fragile than single-color. Chips along the bezel edge are common and significantly devalue the watch — a chipped Pepsi bezel can cost $2,000–$4,000 to replace through official service.
- Inspect bracelet stretch. Oyster bracelets show wear sooner than Jubilee — check that the bracelet sits taut on the wrist without significant play. Overstretched bracelets require link replacement or full bracelet swap.
- Confirm dial and hands are correct. No aftermarket luminous repaints, no replaced hands, no non-factory dial modifications. The GMT hand should be the correct color for the reference (red on Pepsi, black on Batman).
- Insist on full set for top-range purchases. Box and papers (chronometer certification card, warranty booklet, tags) are essential when buying a watch at the $15,000–$25,000 secondary market level. A loose GMT without papers trades at a meaningful discount, and provenance matters to the next buyer.
- Know the generation. Current-gen (12xxxx references) use Calibre 3285. Previous-gen (11xxxx references) use Calibre 3186. Both are excellent — but know what you're buying.
Our Assessment
For the collector who wants meaningful secondary market appreciation potential beyond the Submariner: the Pepsi, Sprite, and Root Beer variants are the most compelling choices. The Batman remains the most wearable and most available. All four steel GMT-Master II references trade significantly above retail — a reflection of genuine scarcity and sustained demand.
