Hamilton is a true eminent authority in the quite thin circle of American watchmaker, but Hamilton also knows how to place their pieces to get the most attention with appearances in several Hollywood movies or popular series like scrubs. The reissued Khaki SkyMaster UTC is as that a tribute to the first integration of sidereal time, which is a time-keeping system that measures time relative to the motion of the stars around the earth. The watch further is able to tell 24 different time zones and features a 42mm stainless steel case that embodies a Swiss automatic ETA caliber 2893-2 with GMT complication.
