The Oyster Perpetual GMT-Master II 
   
Designed specifically for globetrotters.
 
  Designed specifically for globetrotters.
    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. 
  
 
   
 
  
    24-HOUR ROTATABLE BEZEL 
  
 
  
    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. 
  
 
   
 
  
      BLACK DIAL 
    
 
    Like all Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.
 
 
   
    TWO TIME ZONES 
  
 
  
    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.
