Original Mark 2 dial with UAE Ministry of Defence
Original Mark 2 matte black dial with original UAE Ministry of Defence Eagle crest. This Mark 2 dial type is from the second batch that corresponds with the 5.1 million serial number of this watch. Other examples of this extremely rare watch with this “logo” dial are found in this same serial range. These watches were presented to top ranking military personnel. The dial is signed “Swiss- T<25” referring to the original tritium luminous used on the dial & hands which both have a nice patina. The dial has not been touched and remains in excellent original condition showing some small signs of age.

The case remains in very good condition with some small scratches and light wear from general use. The watch is complimented by a stunning original “fat font” 24 hour “Pepsi” insert. This reference features a plexiglass crystal with “Cyclops” magnifying the date display and a Rolex Twinlock screw down crown.
Rolex Oyster Bracelet
Rolex Oyster bracelet from a later period to the watch. It has the reference 78360 with clasp code VB and 580 end links. The bracelet shows some signs of wear. Bracelets can be resized on request.
Released in 1954, the GMT-Master resulted from Pan Am and Rolex collaborating on a watch that could tell the time in two different places at once
With the further innovation and popularisation of commercial flying, the distances of flights became greater. This resulted in pilots crossing into different time zones more frequently. Thus, a need for uniformity across the industry was borne as potential issues could arise when communicating with ground teams in a different time zone to the pilots. To eliminate these errors, the aviation industry adopted a standard time-zone, Greenwich Mean Time. As such, the GMT-Master’s fourth hand, the 2nd-hour hand, was to stay on Greenwich Mean Time – which is where the name for the watch comes from.
