Having originally been designed as a racing-chronograph, the watch would later find its true calling on the wrist of NASA astronauts as America developed a daring plan to be the first nation to put men on the Moon. And, while most of you already know that the Speedmaster is “the moon watch,” there is a lot more to the story, and it always helps to hear the history from the men who made it happen.
