Very rare antique 14 karat gold case LONGINES wrist watch with PEPSI COLA advertising face, I'm guessing from the 1930's.  This watch is Swiss made and has a beautiful and functional 17 Jewel movement.  I am not sure how well it keeps the time as I haven't tested it.  It has a nice calf skin strap which is in excellent condition.  Please feel free to ask questions or to request specific photos.
