Steel and Gold

Unlike the steel cased and gold cased 1675s, steel and gold cased 1675s were not made in the early years of the model run. Colloquially referred to as “two-tone,” steel/gold cases were first introduced to the GMT-Master line in approximately 1970. These models are referred to technically as the 1675/3 GMT-Master I, with the “/3” denoting the steel/gold case; 1675/1 is the technical reference denoting the steel cased version and 1675/8 the 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.

Unlike the steel model, both the steel/gold and gold 1675s came with two dial color options, black and brown. Brown dials were offered first, shortly followed by black dials, and 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 1675/3. You can find the dials available in the 1675/1 and 1675/8 by going to the “Steel” and “Gold” menu headers, respectively.
