Swatch Automatic SAM100 Rubin 1991 Swiss 23 Jewel New Old Stock NOS

First-year Swatch Automatic history -- the 1991 SAM100 "Rubin," a genuine milestone piece with a skeletonized dial that shows off the 23-jewel Swiss movement in motion. New old stock, sealed and unworn, with its original box and price tag still attached. A real find for any Swatch or automatic collector.
