Rolex Moon Watch
Apollo XIII NASA Astronaut, Jack Swigert gave Rolex executive Rene-Paul Jeanneret the watch he wore when he flew to the Moon and back and he wrote an inscription that reads:
"To my longtime friend Rene' Jeanneret who enabled me to always be on time, with sincere thanks." –Jack Swigert
Rene-Paul Jeanneret was a highly influential, innovative and ultra-creative Public Relations Director at Rolex Geneva during the 1950s & 1960s.
It is not easy to read, but in the upper right hand corner of the display below it reads: "This watch was flown to the Moon on Apollo XIII, April 11-17, 1970."
