The GMT-Master II 126710BLNR — the "Batman" — is the Pepsi's sibling and current production counterpart. While the Pepsi was discontinued in February 2026, the Batman remains in production on the Oyster bracelet. With the Pepsi gone, the Batman is now the only steel GMT-Master II in active production, a status that has direct implications for its grey market premium: demand that previously split across two references now concentrates on one.

For the first time since Rolex introduced the two-bezel GMT lineup, there is only one steel GMT-Master II in production. The Batman now occupies a position of sole supply in a category with consistently strong demand. This matters because GMT functionality — the ability to track two time zones simultaneously — is practical, not merely aesthetic. Pilots, bankers, frequent travellers, and global business professionals have genuine use-case demand for the complication that does not fluctuate with luxury sentiment.
The Batman's premium has historically traded at a slight discount to the Pepsi, reflecting the Pepsi's stronger cultural cachet. With the Pepsi discontinued, this discount calculus changes: buyers who want a new steel GMT with Rolex's latest movement, from an authorised dealer, have one option. AD allocation for the Batman will tighten as demand consolidates. The grey market premium should follow.
"The Batman became the only steel GMT Rolex makes. That is not an accident of timing. That is the setup for a premium re-rating."
The black/blue colour combination is considered by many collectors to be more wearable than the Pepsi's red/blue — less casual, more versatile across formal and informal wear. For buyers with a practical orientation rather than a collector orientation, the Batman is frequently the preferred choice.
