Ansonia Clock Co. “Sunwatch”, ca. 1924.  About the size of a credit card, the brass case flips open to reveal a compass (working) and a sundial with an arm that lifts up to provide the needed shadow for determining the time.  There is a booklet that tells you how to determine the time at your latitude and time of year, with a Table of Latitudes for major cities on the inside cover.  Of course, if you’re in one of those cities you probably don’t need a sundial to learn the time, but you get the idea.  Too complicated for me, but boy scouts in 1925 could manage it.  The cardboard case is in good shape, although one flap has torn off (but is still present).  You can find these on eBay, selling for from $45 to $500 (that’s just crazy).  $50–$100.
