Zodiac Astrographic SST Mystery Dial wristwatch

Partially verified

The Zodiac Astrographic SST wristwatch is stated by the source to date to circa 1969. It features a space-age mystery dial construction utilizing transparent discs to give the impression of floating hands, alongside a red dot indicator and a round date window at 12 o'clock. The source records a gold-plated cushion case measuring 40 mm in width, housing an automatic 17-jewel Zodiac calibre 88D mechanical movement. The champagne-toned sunburst dial displays the brand name, 'ASTROGRAPHIC SST', 'AUTOMATIC', and 'SWISS MADE', framed by a dark outer minute track.
