a nicely preserved 16760 aka Fat Lady - the first GMT Master II.   The particular example has a very nice patina dial with some slight topicalization.  The case is sharp and unpolished with clear numbers.  The bezel is sharp and the insert has faded to a nice muted red.  The bracelet is originally fully linked.  The movement is running well and keeping excellent time however last service is unknown.  The watch is accompanied wit its original box, papers, serialized hang tag and oyster booklet.  A very nice collectible neovintage rolex from the 80s.
