The Story

Model 1675, introduced in 1960, kept the original GMT-Master's ability to show the exact time in two time zones at once, and added protective crown guards around the winding crown. The earlier GMT-Master models had none.

This example is in stainless steel. For the two-tone version, see the GMT-Master 1675 in steel and gold.
