Lord Elgin “Jason” Case 2243

My guess is that this Lord Elgin is from the late 50s, or early 6os.  It uses the 23 jewel, 770 movement.  The case is 10k white gold filled and it is fitted with the correct raised/curved crystal.  I don’t have a name for it as of yet.  Diveboy found the name, it is the Jason.
