Times change. When travelling, for example. Business travellers, pilots and globetrotters on a private mission migrate by aircraft between different time zones all within the space of a few hours.

Thanks to this watch's rotating bezel with a black Cerachrom dial, it is possible to read the time in three time zones down to the second with a 24-hour gradation, and to read two times simultaneously.

Uniquely conceived for the demands of international flight routes, the GMT Master has not only become the official standard timepiece for a number of airlines, but in the Blaken-refinement it has become a companion for numerous Rolex fans: precise, reliable, uncompromisingly valuable and chic.
