The Rolex Oyster Perpetual GMT-Master II (m126720vtnr-0001 / ref. 126720VTNR) is a 40 mm Oystersteel travel watch designed to track multiple time zones with maximum clarity and durability. It features a black dial with a highly legible Chromalight display and a bidirectional 24-hour rotatable bezel fitted with a two-color green and black Cerachrom ceramic insert, an exclusive color pairing reserved for this model.
This “traveler’s GMT” setup combines standard hour/minute/seconds hands with an arrow-tipped 24-hour hand for home time. Local time can be adjusted in one-hour jumps forward or backward via the crown without stopping the minutes and seconds, so you can change time zones without sacrificing precision, while the instantaneous date is aligned to local time. A distinctive design signature of this reference is its left-side crown and crown guard, with the date window and Cyclops lens positioned at 9 o’clock.
Inside is the Rolex calibre 3285, a self-winding movement with ~70 hours of power reserve, stop-seconds for precise setting, and Superlative Chronometer performance rated at −2/+2 seconds per day after casing. The monobloc Oyster case with Triplock screw-down crown provides 100 m / 330 ft water resistance. It’s fitted on an Oyster bracelet with an Oysterlock safety clasp and Easylink 5 mm comfort extension for quick fit adjustments.
