With Rolex presentation box.
The present example of a Rolex reference 1675 features a very charismatic dial, that has aged to a dark chocolate brown, which is further complimented by the ivory-white color of the luminous material, and the black bezel.
Reference 1675 was introduced in 1959, following the success of the original GMT-Master reference 6542 in 1954. Upon its introduction, the reference was available in 18k yellow gold or stainless steel, however the yellow gold version originally came without crown guards, and were only introduced in 1967 to match their stainless steel counterparts. Starting in the 1970's, Rolex also produced versions in steel and gold together, a metal combination the company marketed as "Rolesor". Reference 1675 was in production until 1980.
