I just thought this event was almost 30 years ago. When I became a serious fan of JMJ, AOR was 19 years old and the Swatch the World event was not even conceived. I couldn't go myself, I just started my study computer engineering when the event was held. But I did manage to get some newspapers with articles on these festivities commemorating the 100 millionth Swatch sold.
Here are scans of the Swatch World Journal, which was released after the Swatch The World event.
