About the GMT-Master II family
The GMT-Master II arrived in 1983 with ref. 16760, adding an independently adjustable hour hand so the watch could show a third time zone with the bezel. The ref. 16710 that followed is known for its many aluminium bezel colours. In 2007 the ref. 116710LN introduced a Cerachrom ceramic bezel.
The current generation uses caliber 3285 and includes the 126710BLRO (red and blue) and 126710BLNR (blue and black) in steel, the Everose Rolesor 126711CHNR, the left-handed 126720VTNR with its crown at 9 o'clock, and grey and black bezels from 2024 on refs. 126710GRNR and 126713GRNR. Dealers always state the bezel colour code, the bracelet (Oyster or Jubilee) and the year on the card.
