Shinola Watch Blue Monster GMT

First developed for commercial airline pilots in the 1950’s, GMT watches are the perfect traveler’s companion. The 40mm Monster GMT features a fourth hand that rotates once every 24 hours—meaning the wearer can check against the ceramic bezel insert marks to track time in multiple time zones.
Short for Greenwich Mean Time, GMT is the earth’s average solar time according to the Royal Observatory in Greenwich, London. Pilots reference GMT as they soar through global time zones, giving a name to this extraordinary time-keeper.
