While the steel cased 1675 is the prototypical GMT-Master, the gold cased 1675 was also made throughout the entire model run from 1960-1979. This model is referred to technically as the 1675/8 GMT-Master I, with the “/8” denoting the gold case; 1675/1 is the technical reference denoting the steel cased version and 1675/3 the steel/gold version. Notably, the 1675/3 and 1675/8 from the 1970s share some components and differ in others, as shown in the table below. This table only applies to the 1970s watches as the 1675/3 was not produced in the 1960s.

Unlike the steel model, both the steel/gold and gold 1675s came with two dial color options, black and brown. Brown dials were offered throughout the model run while black dials were produced shortly after the introduction of the 1675/3 steel/gold model in the early 1970s; both were produced until the end of the 1675 in 1979. Given the stark difference between the two, and because the 1675/8 was produced throughout the 1960s and had additional dial and handset variations, I have split their categorization first by case metal and then by dial color. Below are the dials available in the 1675/1. You can find the dials available in the 1675/1 and 1675/3 by going to the “Steel” and “Steel and Gold” menu headers, respectively.
