Rolex GMT-Master II "Batman" 126710BLNR (2026)

The Batman is the modern classic of the GMT-Master II line. When the blue and black bezel debuted in 2013, it was the first two-colour Cerachrom insert Rolex had made from a single piece of ceramic, and it has been one of the most sought-after steel sports watches ever since. This 2026 example pairs that bezel with a 40mm Oystersteel case for a cooler, more understated look than its red and blue sibling.

The black lacquer dial is clean and legible, with white gold hour markers, a blue GMT hand and Chromalight lume that glows blue in low light. A sapphire crystal with Cyclops lens sits over the date at 3 o'clock.

Inside is Rolex's calibre 3285, a Superlative Chronometer accurate to -2/+2 seconds per day, with a 70-hour power reserve and an independently adjustable hour hand for changing local time without stopping the watch. The 24-hour bezel and GMT hand track a second time zone at a glance, and the Triplock screw-down crown gives 100 metres of water resistance.

It is fitted on an Oyster bracelet with an Oysterlock safety clasp and Easylink 5mm comfort extension.
