Rolex GMT-Master II 126710BLNR
Specs, Market Price & Buying Guide
- The Rolex GMT-Master II 126710BLNR 'Batman' pairs a black-and-blue Cerachrom bezel with a Jubilee bracelet and the 70-hour Calibre 3285 true-GMT movement.
- Retail is roughly $10,900, but real transaction prices run about $14,000-16,500 — the premium is the price of skipping the AD waitlist.
- Weak points: the hefty gray-market premium, a thick 12.1mm case, and the fact that a Tudor Black Bay GMT does 90% of the job for a third of the money.
Rolex's steel sport formula — the Batman adds the two-tone Cerachrom bezel and a second timezone.

The Batman peaked near $19k in the 2022 frenzy and has bled slowly since. It remains one of the most liquid steel Rolexes — spreads between buy and sell prices are thin for the segment.

How it wears, by wrist size
A lot of watch — the 40mm case and slab sides overwhelm small wrists.
Wearable; the Jubilee dresses it down nicely.
The sweet spot — wears like the icon it is.
Perfectly proportioned; crown guards never dig in.
Buy or skip?
5/5 at retail, 3/5 at gray-market prices
As an object, the Batman is close to perfect: the best travel movement in the business, a bezel that will never scratch or fade, and looks that work from cockpit to boardroom. The question is purely financial — at $14k+ you're paying a $3-5k convenience tax over retail. If a great AD relationship or patience can save you that, take it.
- You actually need to watch value retention closely — premiums can compress further.
- You want slim; at 12.1mm it wears tall under cuffs.
- You only travel occasionally — a Tudor BB GMT or even a quartz GMT covers the use case.

Frequently asked questions
Batman vs Batgirl — what's the difference?
Same watch, two bracelet moods. The 2019 BLNR on Jubilee earned the 'Batgirl' nickname for its dressier drape; the 2021 Oyster-bracelet version reclaimed 'Batman'. Reference is 126710BLNR either way.
Is the GMT-Master II a true GMT?
Yes — the local hour hand jumps independently in one-hour steps, so you set home time once and hop timezones without stopping the watch.
Will Batman prices keep falling?
Nobody knows, but the post-2022 trend has been a slow bleed rather than a crash. Buy it because you want to wear it; the premium is a consumption cost, not an investment.
Batman vs Pepsi (BLRO) — which is better?
The Pepsi is the historic icon and carries the bigger premium; the Batman is the modern favorite and slightly easier to get. Mechanically identical — buy the bezel you love.
Where to buy safely
~$10,900 retail if you have the relationship — the only price that makes this a 5/5 buy.
$14,000-16,500 immediate. Use established dealers with authentication and returns.
2019-2021 cards trade at the bottom of the range; check bezel condition and card completeness.
