Quick answer: The Coke is the black-and-red bezel version of the Rolex GMT-Master II, the nickname attached to the classic reference 16710 and its red and black 24-hour insert. A replica Rolex GMT Master II Coke copies that look with a 40 mm steel case, a bidirectional 24-hour bezel, and a fourth hand for tracking a second time zone. Strong replicas nail the silhouette; weak ones expose themselves through the bezel insert, the GMT hand function, and the case profile.
What "Coke" Means in GMT-Master Language
Collectors named GMT bezels after drinks and characters. Knowing the lineup helps you spot a seller who mixes them up.
- Pepsi: blue and red insert, the original 1955 color split
- Coke: black and red insert, the subject of this guide
- Batman / Batgirl: blue and black ceramic insert, Batgirl meaning the Jubilee bracelet version
- Bruce Wayne: grey and black insert
- Sprite: green and black insert with the winding crown on the left
The black-and-red pairing first appeared on the reference 16760 in 1983, a thicker case that earned the nickname "Fat Lady." It became the standard Coke look on the reference 16710, built from 1989 to 2007. Rolex has not offered a black-and-red bezel on a current production GMT-Master II, which is part of why the reference keeps drawing attention.
Specs a Replica Coke Should Match
- 40 mm case diameter with a 20 mm lug width
- Stainless steel case (the original 16710 used 316L, not the 904L that arrived with later references)
- Bidirectional 24-hour bezel with an anodized aluminium insert
- Sapphire crystal with a cyclops magnifier over the date
- Black dial, luminous hour markers, and a GMT hand with an arrow tip
- Oyster or Jubilee bracelet, since both were offered on the reference
How to Judge a Replica Rolex GMT Master II Coke
The GMT hand has to set independently
This is the feature that separates a real GMT from a costume piece. On the genuine design, the crown's middle position jumps the 12-hour hand in one-hour steps while the GMT hand keeps running against the 24-hour scale. That means you can move the local time forward or back during a flight without losing your home-time reference. Cheap replicas either slave the GMT hand to the hour hand or hand it a separate setting position, which breaks the whole point of the watch. Before buying, read the product notes for a clone movement or a stated independent hour hand, and ask the seller to confirm how the crown positions behave.
Bezel insert material and color
The Coke should have an anodised aluminium insert, because that is what the reference used. The red half should read as a deep, even red rather than orange or maroon, and the black half should be uniform with no blotching near the numerals. Weak inserts print numbers that sit flat or wear at the outer edge. Check the bezel action too: rotation should feel smooth and firm in both directions, without back play or a gritty scrape.
Case, lugs, and crystal height
Look at the lug profile and the crown guards. On a good build the lugs taper cleanly, the brushing is consistent, and the crystal sits close to the bezel instead of rising into a tall dome. A milky or heavily domed glass is one of the easiest tells in photos.
Dial, date, and lume
Printed text should be sharp, "Swiss Made" should sit correctly at the bottom of the dial, and the date font should not look wide or squat. The cyclops should magnify the date without distortion, with the date centered in the window. Early genuine dials used tritium, while later examples moved to Super-LumiNova, so a replica claiming tritium should show a matching aged tone rather than bright white.
Bracelet and clasp
Solid end links should sit flush against the case with no visible gap, and the clasp should close with a firm snap. On the Oyster bracelet, check that the centre links are polished where they should be and that the brushing runs in one direction. Jubilee builds need tight, equal gaps between the five rows.
Movement Choices in Replica GMT Builds
Most replicas in this style use an automatic movement that copies the 3186 or the newer 3285 architecture, both of which support the independent jumping hour hand. Entry-level builds often run a generic automatic with a 24-hour hand that does not jump, which is why the movement description matters more than the case photo. Treat any claimed power reserve or water rating as a marketing claim until you see it confirmed.
What Different Price Bands Actually Get You
- Budget builds: correct overall proportions but a slaved GMT hand, painted or poorly anodised insert, and a light bracelet.
- Mid-tier builds: clone-style movement with a working jumping hour hand, better insert colour, and improved bracelet solidity.
- Top builds: closer case profile, crisper dial printing, less crystal dome, and a bezel action that feels deliberate rather than loose.
Care and Ownership Notes
Do not treat a replica as a dive watch, even if the listing quotes a depth figure. Have the caseback gasket checked before wearing it near water. Aluminium bezel inserts scratch easily, so skip abrasive polishes and use a soft cloth with mild soap. Keep the watch away from strong magnets, which can pull a mechanical movement out of regulation.
Legal and Ethical Note
A replica is not made, sold, or authorised by Rolex SA, and Rolex and GMT-Master are trademarks of their owner. Importing or reselling counterfeit watches can carry legal consequences depending on where you live. Buy with your local rules in mind, and never present a replica as a genuine watch, whether in a sale, an insurance claim, or a repair shop.
Common Questions
Is the Coke still in the current Rolex catalog?
No. The black-and-red insert belongs to older references, while current GMT-Master II models use other bezel combinations.
Will the GMT hand on a replica track a second time zone?
Only if the movement supports an independent hour hand. Confirm the movement type with the seller before ordering.
Does a replica Coke use a ceramic bezel?
It should not if it copies the reference look. The black-and-red Coke used an aluminium insert, and ceramic versions belong to newer models.
