Thanks to Omegaforums.net we can be
99% sure that US Marine Corps aviator LtCol Gerald Carr took a Movado Datron chronograph aboard SL-4 mission... 46 years ago!
Going a bit deeper on this topic, I always mentioned that the 3 manned Skylab missions have been a bit neglected by both spaceflight & horology aficionados.
Unfairly as already on Skylab-3 Owen Garriott was rumoured to have taken extra Seiko wristwatches aboard America's first space station.
Of course during Skylab-4 William Pogue wore the well-known Seiko 6139 automatic chronograph, and commander Gerald Carr a Movado Datron.
Preflight suit-up photos revealed that science pilot Edward Gibson also wore an extra wristwatch underneath the spacesuit. MoonwatchUniverse tends towards a Speedmaster Mark II as Gibson was wearing a Mark II Speedie during training between October 1972 and November 1973.
Post-mission Gibson was also pictured with his personal
Omega Speedmaster MkII chronograph although I yet have to find an actual spaceflight mission photo showing the Mark II in space... US Navy recovery photos also don't show the Mk II... thus far...
