In 1956, Pan American Airlines flew the first successful intercontinental jet passenger plane, the Boeing 707. By cutting the journey time in half to 7 hours, travellers suffered a new phenomenon of jet lag. One solution to help pilots adjust and maintain full awareness was to keep them on home time, while still being informed of the time at the present location. This is where Pan Am commissioned Rolex to develope the G.M.T. Master, named after the world's standard time, the Greenwich Mean Time.
The reference 6542, produced in 1956, and only until 1959, featured a 24 hour driving wheel, four hands including a 24 hour hand and a rotating bezel made from bakelite calibrated for 24 hours allowing the wearer to always be able to tell the time on two zones. Bakelite was chosen as a material for the bezel to reduce reflection which could disturb the pilots.
Most of the early watches produced were given to each of Pan Am's pilots, first officers and navigators.
The 6542 was replaced in 1960 by the reference 1675, a slightly larger version with a brand new movement, metal bezel insert and protected crown.
