While Apollo program astronauts received their official Omega Speedmaster to wear on link the outside of their spacesuits a few also wore private watches under their suits. link Jack Swigert wore his GMT-Master on Apollo 13 Rolex had this watch on display at Watches amp Wonders 2023 so I assume it's a part of Rolex's collection. The only other space-flown Rolex that's been sold publicly is Ron Evan's Pepsi GMT-Master link which sold at Heritage Auction in 2009 for 131450.

When the "new" Ploprof was announced in 2009 more on that later Tom Nesbit link saw at least two vintage examples a month come into his shop Nesbit's Fine Watch Service in Seattle for restoration. This anecdotal observation link is in line with the story link the auction numbers tell with a spike in interest during the relaunch.
