The steel Rolex GMT-Master II “Batman” and “Pepsi” on Oyster bracelets share the same basic GMT purpose and a closely related design, but their bezel colors give them distinct looks. The blue-and-black Batman is reference 126710BLNR; the blue-and-red Pepsi is 126710BLRO. Rolex’s current product page supplies detailed specifications for the Batman Oyster configuration, while its brochure identifies the Pepsi Oyster configuration. The nicknames are common shorthand, not Rolex model names.
Which watches are the Batman and Pepsi?
“Batman” refers here to the Oystersteel GMT-Master II reference 126710BLNR, with a black dial and a two-color blue-and-black Cerachrom bezel. “Pepsi” refers to the Oystersteel reference 126710BLRO, whose bezel is blue and red. Rolex’s brochure depicts the Pepsi with an Oyster bracelet; the nickname itself is informal rather than an official designation. Rolex’s Batman Oyster product page and its 126710BLRO brochure establish these configurations.
Batman or Pepsi: what is the difference?
| Feature | Batman | Pepsi |
|---|---|---|
| Reference | 126710BLNR | 126710BLRO |
| Bezel colors | Blue and black | Blue and red |
| Bracelet in this comparison | Oyster | Oyster, as depicted in Rolex’s brochure |
| Published technical detail available in cited Rolex material | Rolex’s current Oyster product page lists the specifications below | The cited brochure identifies the Oystersteel watch and Oyster bracelet; it does not provide a complete specification listing here |
The practical distinction established by these sources is the bezel colorway. They do not establish that one is more comfortable, lighter, better finished, or preferable on the wrist; those judgments require direct inspection. Rolex product material also does not support a claim here about current stock, production status, or market value.
What does the Oyster bracelet add?
The Oyster bracelet is built from three-piece solid links. Rolex’s contrasting Jubilee design uses five-piece links, so the bracelets differ in link architecture and appearance, not merely in name. On the cited Batman Oyster page, Rolex specifies an Oysterlock safety clasp and an Easylink comfort extension that adds approximately 5 mm. The Batman Jubilee page describes the same clasp and extension system. These details are documented for the Batman configurations; do not assume the cited Pepsi brochure independently confirms every clasp specification. See Rolex’s Batman Jubilee page for the comparison.

How does the GMT-Master II show two time zones?
The arrow-tipped 24-hour hand works with the bezel’s 24-hour graduations to indicate a reference time, such as home time. The local hour hand can be set independently, letting the wearer adjust local time without changing the reference hand. Rolex explains that the 24-hour hand displays the “home” reference time, read against the bezel graduations, and describes the GMT-Master II’s functions on its GMT-Master II features page.

How to choose between them
- Choose by bezel color: the Batman pairs blue with black; the Pepsi pairs blue with red. The cited material does not support a functional advantage for either colorway.
- Confirm the bracelet configuration: this comparison is specifically about Oyster-bracelet watches. Rolex also lists a Batman Jubilee configuration, so verify the bracelet on the exact watch being offered.
- Check the exact reference and regional details: ask an official Rolex retailer to confirm reference, bracelet, local pricing, and current availability. Rolex says its watches may be sold and maintained only by official Rolex retailers; consult its GMT-Master II newsroom page for collection information.
