A Fantastic and Unique 1675 from 1968 .  The dial has an interesting textured look we have seen on some GMTs of this era.  The dial is a very dark chocolate brown hard to capture in photos but def faded from the normal jet black.  The patina on the excellent puffy lume has aged to a deep  pumpkin color with hands that have aged slightly differently over almost 60 years.  The insert is 100% originally faded from black to ghost brown with small triangle period correct for this watch.  The case is worn but never professionally polished . For those familiar with cases of the late 60s you can appreciate the wide chamfers and sharp crown guard.  The bracelet is a 7836 with 12 links and has some stretch.  The movement is running well and keeping excellent time however last service is unknown
