Rolex Caliber 3186

Since 2005, the Rolex GMT-Master 2 has been powered by the Caliber 3186. The added GMT module makes Rolex’s latest time zone caliber slightly higher than the 3135 on which it is based. In 2018, however, its successor the Caliber 3285 has been introduced, which will take its place from now on.

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”.
