It established the aesthetic and technical codes that would define this legendary model: Oyster case, additional 24-hour hand, bidirectional rotating two-tone bezel graduated to 24 hours, allowing the simultaneous reading of a second time zone. Ref. 1675, produced from 1959 to 1980, marks the model's maturity: crown guards, calibre 1565 then 1575, 50-metre water resistance. It is succeeded by Ref. 16750, the first to receive the quickset; then by the GMT-Master II, opened in 1983 with Ref. 16760, whose calibre 3085 permits, for the first time, the independent setting of the hour hand. Technical evolutions follow: transition from plexiglas to sapphire, calibres 3185 then 3186, generalisation of the Cerachrom ceramic insert from 2005, water resistance increased to 100 metres.\u003c\/p\u003e\n\u003ch3\u003eCharacter\u003c\/h3\u003e\n\u003cp\u003eTwo-tone gold and steel configuration, black dial with applied gold indexes and gold hands.\u003c\/p\u003e\n\u003cp\u003eServiced in-house.
