Rolex GMT-Master 16578 Black Dial and Bezel – 18K Yellow Gold Jubilee Bracelet – Rolex Warranty

ROLEX GMT-MASTER 16578 BLACK DIAL AND BEZEL – JUBILEE BRACELET IN 18K YELLOW GOLD – ROLEX WARRANTY

The GMT has been a staple model in Rolex collections since its introduction in 1954. It was initially designed in collaboration with Pan American World Airways (an airline, which filed for bankruptcy in 1991 and was partially purchased by Delta Airlines). In the 1950s, the aviation industry gained great popularity and pilots and their crew began to undertake more long-distance flights. This was why Rolex introduced the GMT Master for Pan Am. The bezel (24-hour indication) was a key innovative feature that allowed the wearer to reference two different time zones simultaneously. The fourth hand (24-hour display) allows the wearer to set the watch to any time zone for the main time display, then set the rotating 24-hour scale bezel to a second time zone. For those who don't know, GMT stands for "Greenwich Mean Time"
The Reference 16758 was first introduced in 1980 shortly after the Ref. 16750 and was in production until 1988. Both the 16758 and 16750 featured the Cal. 3075 quick date movement, but the 16758 also included additional changes.

This second-wrist Rolex GMT-Master reference 16758 has the following features:

18K yellow gold Jubilee case and bracelet
Black dial and bezel
