The 1675 GMT Master was produced between 1959 and 1980. This was the first watch that was available with both an Oyster and Jubilee bracelet. On many models, the dial markers have since turned a creamy color, and the “Pepsi” bezels have faded over the years, turning the colors to lighter shades of blue and red (almost pink). Interestingly, this makes the models more sought after by vintage watch collectors. The 16750 was released in 1980 with a new movement. The model offers the more modern quickset date function. Only in production until 1988, it is a highly sought after model. The 16750 offers the perfect combination of both modern features but a vintage vibe.
