Rolex Perpetual GMT-Master II 116710ln Series

Designed to show the time in two different time zones simultaneously, the GMT-Master, launched in 1955, was originally developed as a navigation instrument for professionals criss-crossing the globe.

In addition to conventional hour, minute and seconds hands, the GMT-Master II features an arrow-tipped hand, which circles the dial once every 24 hours, as well as a bidirectional rotatable 24-hour graduated bezel.

With traditional hour, minute and seconds hands, a triangle-tipped 24-hour hand, and a bidirectional rotatable bezel with 24-hour graduated Cerachrom insert, the GMT-Master II can display the time in two time zones simultaneously: either the local time and the reference time, or the local time and that of an alternative time zone. The date, at 3 o’clock on the dial, is synchronized with the local time.
