When Rolex introduced the GMT-Master 2, powered by the new 3085 Caliber, in 1985, it was able to display an additional time zone with an independently adjustable hour hand. This was followed in 1988 by the Caliber 3185 and then in 2005, now equipped with a Parachrom hairspring and date quickset, the Caliber 3186. Its successor, Caliber 3285, was presented at Baselworld 2018 together with the new GMT-Master 2 “Pepsi”.
