·The various sources citing serials for the NASA watches suggest one of two things. Either the lists are very very inaccurate or more likely there was a lot of switching out of movements back in the 1960s since many of the serials are impossible for the models. There is at least one flown straight lug which now has a 861 inside and has been that way since the 1970s. Be careful assuming too much from a serial, these were tool watches and treated as such.
