1960 or before Longines Automatic Mechanical mens watch.   1200 model, 10kt gold filled. 

The watch has a detailed engraving on the caseback.  Arthur H. Stoeckmann, a Masonic Compass Sun, 1960, St Paul Lodge No. 3 AF & AM

Known details:

Mr. Stoeckmann 1911-1993 served as SSGT during WW II  in the US Army

St Paul Lodge No. 3 is the oldest Lodge in Minnesota

The watch works and keeps time however,  the crown seems to want to not catch at times.  When attempting to wind it will sometimes want to move the hands.  It is a model 1200 but no attempt to remove caseback was made.  Unsure if this would be considered an "Admiral" as it is not on the dial.  The Crystal has some light scratches but overall good shape for age.

The Speidel wristband is all metal but has the appearance of leather.  Not measured but would need a link or two removed for average size wrist.   It could definitely use a cleaning.

A fine addition for either the watch or Freemason collector.
