This is a vintage Swatch Watch known as Jelly Fish GK100 from the 1985 Spring Summer Collection.  This watch is running (note the second hand) and keeping perfect time with a new and included battery.  It is the rare thin hands version, and it is in fantastic condition.  The serial number indicates it was made in 1984, which makes it very rare.  It has the very rare original seven holes jelly bands.  Watch will be sent insured, and you have the option to upgrade to Priority Mail.
