Bulova Accutron Mark II (2185)
Bulova Accutron Mark II (2185). Great shape, next to no wear on the glass, and crowns. Fully functioning, and just looked over by a local jeweler shop. The design of the original Accutron movement was finalized in the latter half of the 1950s, with Bulova placing tuning fork timers on early spacecraft and satellites. An Accutron timer was placed in the Explorer VI and Explorer VII unmanned orbiters in 1959 and another was used to switch transmission of data aboard Explorer XI on April 27, 1961. Accutron timers and watches would later be used on satellites (Telstar, Tiros, Syncom, Pegasus, and LES), in spacecraft (Explorer, Mercury, Gemini, Agena, and Apollo), and on the wrists of astronauts. 2185 ("Astronaut Mark II" with "home time" and independent "away time" hour hands and second crown at 2:00).
