Submariner 11661 replica

The GMT-Master was originally designed to help professional pilots navigate long flights. The distinctive and easily recognizable design features a bidirectional rotatable bezel and a 24-hour graduated insert, as well as a number of two-tone inserts, with the lower half representing daytime and the upper half representing nighttime.

As a practical watch, it has been continuously improved over the years, with its technical performance consistently enhanced. In 1982, Rolex introduced the GMT-Master II, equipped with a movement that allowed the hour hand to be adjusted independently, setting it apart from the other hands.

With its standard hour, minute, and second hands, the 24-hour hand with a triangular arrow, and a bidirectional rotatable bezel with a 24-hour graduated Cerachrom insert in ceramic, the GMT-Master II shows the time in two time zones at the same time: local time and departure time, as well as local time and time in a third time zone. The calendar display is synchronized with the local time.
