This ball-point pen was constructed by the Fisher Pen Company, makers of the "space pen". It displays the (then) newer technology of a clock in the pen with a liquid crystal display. The pen was battery driven, but was not flown or used during spaceflight.
Donated to the National Air and Space Museum by the Fischer Pen Company in 1978.
