It established the aesthetic and technical codes that would define this model that would become legendary: Oyster case, additional 24-hour hand, bidirectional rotating two-tone bezel graduated to 24 hours allowing 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, water resistance 50 metres. It was 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 enabled, for the first time, the independent setting of the hour hand. Technical evolutions followed: the move from plexiglas to sapphire, calibres 3185 then 3186, the generalisation of the Cerachrom ceramic insert from 2005, and water resistance increased to 100 metres.\u003c\/p\u003e\n\u003ch3\u003eCharacter\u003c\/h3\u003e\n\u003cp\u003eCollectors call this a \"nipple\" dial, after the raised gold of its indexes. Over the years their luminous material has taken on a cream tone. The gold of the bezel and crown warms the steel of the case, and on leather the pilot's watch takes on a dressier air.\u003c\/p\u003e\n\u003cp\u003eServiced watch. Very good condition.
