One Giant Leap for Watchmakers

Buzz Aldrin may have been only the second man to walk on the moon, but he was the first to wear a watch on its surface. In 1962 Nasa visited a jewellery shop in Houston, bought some timepieces, and subjected them to what agency historians describe as ‘exhaustive tests aimed at determining performance reliability in the conditions likely to be experienced during EVA'. That acronym stands for ‘extravehicular activity’, which means moon walking, which means temperatures ranging from -250 to +250ºF.
