Astronauts wore Rolex GMT's and not just Speedmasters. Say it isn't so...

Nowadays, the gmt master II is a watch for posturetas.

Watch the prelaunch NASA footage, an interesting moment when the Apollo 14 back-up astronauts join the prime crew...

Social media... ignorance is bliss... Reading most comments on the space-flown Apollo 14 Rolex GMT-master 1675 pilot watch it's clear most people have no clue about "Rolex being worn in space flight missions".
Remember already in October 1967 on X-15 flight 188 (fastest Mach 6.70) and on X-15 flight 190 William "Pete" Knight wore his Rolex GMT-master 1675 above an altitude of 50 miles (80 kilometers) high enough to earn USAF astronaut wings.
In April 1970, Apollo 13 CMP John "Jack" Swigert was the first to wear a Rolex to lunar orbit but Apollo 14 LMP Edgar Mitchell was the first to wear Rolex on the lunar surface as he wanted to gift both daughters something he had worn on the Moon. Besides his NASA-issued Omega Speedmaster number 77, Mitchell wore two personal wrist watches underneath the Apollo A7L space suit. Apollo 14 CMP Stuart Roosa and Apollo 17 CMP Ron Evans also carried their personal Rolex GMT-master 1675 to lunar orbit, while Apollo 17 Moonwalkers agreed to carry Evans's 1675 down to the Moon onboard Lunar Lander "Challenger".
Time-period NASA photos show that at least 20 Gemini-Apollo era NASA astronauts owned a personal Rolex wrist watch, some a Turn O'Graph 6202 or a Daytona 6240 but most owned a Rolex GMT-master 1675 pilot watch;
Aldrin, Borman, Carpenter, Cernan, Collins, Conrad, Cunningham, Engle, Evans, Glenn, Haise, Lovell, Mitchell, Pogue, Roosa, Shepard, Schirra, Swigert, Worden,...

The JB Champion bracelet on the GMT is a nice looking combination, one I’ve worn on a few occasions.

I also see a calendar attached to the bracelet in the enlarged picture.
