very nicely preserved 1675 from 1977.  The dial and hands have aged to a nice dark cream patina and have no issues.   The case is lightly polished in the past however remains thick and even and in excellent vintage condition.  The bezel is sharp and the insert is the original red back.  The bracelet is a 78630 which typical would come with this variant of GMT and it has very little stretch if at all and all of its links.  The movement is running strong and keeping excellent time however last service is unknown.  Comes with original box and oyster manual
