Here is a vintage rectangular early automatic Gruen Precision Autowind with a fancy two-toned silver dial.  Case size is 39mm lug to lug by 25mm wide. The watch is running however an estate find and is in as-found, unpolished condition with some wear on the high points and back edges of the lugs from normal use and some discoloration on the dial.  Please see photos for more detail.  Thanks for looking
