Timer, Skylab

Timers like this were used by astronauts to time experiments and other events during the Skylab missions (1973-1974). This timer is a flight-qualified backup, transferred from NASA and installed in the Skylab orbital workshop on display in the Museum. It has the "Accutron" movement developed by Bulova for wristwatches, on/off switches for the timer and tone, and a small amplifier.
