The Rolex GMT-Master II is the travel watch that made two time zones feel effortless. A bidirectional 24-hour bezel and an independent hour hand let you track home time while local hours jump in one-hour steps\u2014no resetting the whole watch. This Rolex GMT-Master II buying guide covers how the line evolved from the original GMT-Master, which nicknames and references matter most, how calibre 3285 changed the modern generation, and what to check before you buy one pre-owned.<\/p>\n\n\n\n

A Quick Background<\/h2>\n\n\n\n

Rolex introduced the GMT-Master in 1955 for Pan American World Airways pilots who needed a clear second time zone. The defining feature was a 24-hour hand paired with a rotatable bezel marked for a full day. Rolex still describes that aviation origin on its official GMT-Master II pages (Rolex<\/a>). In 1982 the GMT-Master II arrived with a movement that allowed the local hour hand to be set independently of the GMT hand and bezel\u2014the practical jump that separates “II” from the earlier GMT-Master (Rolex<\/a>). For a deeper dive into nicknames and steel sports siblings, see our GMT-Master vs Submariner comparison<\/a> and the Rolex Batman guide<\/a>.<\/p>\n\n\n\n

GMT-Master vs GMT-Master II<\/h2>\n\n\n\n

On a vintage GMT-Master (for example the long-running 1675), changing local time usually meant stopping the watch or resetting both the hour hand and the GMT display together. The GMT-Master II’s independent local-hour hand is the reason most travelers and collectors prefer modern references. Both families use a bidirectional 24-hour bezel; water resistance on current Oyster cases is 100 meters (330 feet), which is fine for swimming but not a dive-watch rating like the Submariner’s 300 meters (Rolex<\/a>).<\/p>\n\n\n\n

Key References and Nicknames<\/h2>\n\n\n\n

16710 \u2014 Pepsi, Coke, and all-black<\/h3>\n\n\n\n

Produced roughly from the late 1980s into the mid-2000s, the steel 16710 is the classic aluminum-bezel GMT-Master II many collectors still chase. Bezels came in red-and-blue (“Pepsi”), red-and-black (“Coke”), and black. Movements were Rolex calibre 3185, with late examples using 3186. Cases are 40 mm with an acrylic-to-sapphire crystal transition already complete by this generation. Condition of the aluminum insert and crown-guard sharpness matter a lot on pre-owned examples; faded “ghost” bezels can be charming or a red flag depending on price.

116710LN and 116710BLNR \u2014 ceramic arrives<\/h3>\n\n\n\n

From 2007 Rolex moved the steel GMT-Master II to Cerachrom ceramic bezels and calibre 3186. The 116710LN used a black insert; the 116710BLNR (2013) introduced the blue-and-black “Batman” Cerachrom that defined a decade of steel sports Rolexes. These watches still wear as modern tool watches, with Maxi dials and heavier Oyster bracelets than the 16710. They are a sweet spot if you want ceramic durability without paying today’s premiums for the newest 126xxx steel pieces.<\/p>\n\n\n\n

126710BLRO and 126710BLNR \u2014 calibre 3285<\/h3>\n\n\n\n

In 2018 Rolex relaunched the steel Pepsi as 126710BLRO on a Jubilee bracelet, powered by calibre 3285 with roughly 70 hours of power reserve and Superlative Chronometer precision of \u22122\/+2 seconds per day after casing (Rolex<\/a>). The following year brought the updated Batman 126710BLNR. Oyster-bracelet options followed later for both colorways. These are the references most shoppers mean when they say “modern Pepsi” or “modern Batman.” See a Pepsi GMT-Master II listing<\/a> and a Batman steel GMT<\/a> on TrueFacet.<\/p>\n\n\n\n

Root Beer, Sprite, and left-handed variants<\/h3>\n\n\n\n

Two-tone and precious-metal Root Beer models (brown-and-black Cerachrom), such as the Everose Rolesor 126711CHNR and solid Everose 126715CHNR, pair warm metals with a softer bezel palette. More recent catalog additions include grey-and-black “Bruce Wayne”\/GRNR steel and gold configurations and the left-handed green-and-black 126720VTNR (“Sprite” \/ “Lefto”), which places the crown and date at nine o’clock for left-wrist wearers. Exact availability at authorized dealers changes; the secondary market is where most buyers find specific combinations without a waitlist.<\/p>\n\n\n\n

How the GMT Function Works Day to Day<\/h2>\n\n\n\n

Set the 24-hour hand to a reference time (often home or UTC) so it points to the correct hour on the bezel’s 24-hour scale. When you land in a new zone, pull the crown to the intermediate position and jump the local hour hand forward or back in one-hour steps; the minutes, seconds, and 24-hour hand stay put. Rotate the bezel if you want a third zone read against the GMT hand. Rolex documents this independent hour-hand design as the core of the GMT-Master II (Rolex<\/a>). If you are new to dual-time watches, our primer on what GMT time means on a watch<\/a> is a useful companion.<\/p>\n\n\n\n

What to Check Before You Buy Pre-Owned<\/h2>\n\n\n\n

Buy from a seller who authenticates Rolex thoroughly\u2014case reference and serial between the lugs (or laser-etched on newer cases), movement finishing consistent with the era, and a bezel insert that matches the reference. Ceramic Cerachrom inserts should show crisp, filled numerals; aluminum inserts on 16710s often fade, which is expected, but aftermarket inserts are common and should be disclosed. Watch for polished-away crown guards, re-lumed hands that do not match Rolex’s luminous material for the period, and bracelets stretched beyond serviceable tolerances. Prefer boxes and papers when the premium is modest, but a correct, serviced watch from a reputable platform often matters more than a worn card. TrueFacet’s Authenticity Promise<\/a> and the broader Rolex watches<\/a> catalog are built around that authentication-first approach.<\/p>\n\n\n\n

Sizing and Wear<\/h2>\n\n\n\n

Modern GMT-Master II cases are 40 mm with a substantial presence on the wrist, especially on Oyster bracelets. Jubilee bracelets wear slightly dressier and often feel more flexible. If you are between sizes, Rolex’s Easylink-style clasp extensions on recent Oyster and Jubilee bracelets help with daily comfort; our guide to how tight a watch should be<\/a> covers fit in more detail. Water resistance is 100 meters\u2014rinse after salt water and keep the crown screwed down.<\/p>\n\n\n\n
