Bulova Accutron TE-14  
Written by Accutron on 2009-12-27  

The Bulova Accutron TE-14 Calendar Clock is a small panel-mount clock with a 1000-day resettable counter. The TE-14 is based on a standard Accutron 214 tuning fork movement, used in early models of Accutron wristwatch. Folklore states that this specific type of clock was used in Cold War-era photographic reconnaissance aircraft. The TE-14 was also available with a 1-31 day display in place of the 1000-day counter.

Bulova's earliest contributions to the US space program consisted of Accutron instrument timers, used aboard numerous satellite and manned flight programs. The Bulova Timer Laboratory ultimately produced over 200 different models of military and industrial instrument timers with specialized complications, including a 1000-day counter, a 5-year switch, a cycle timer and a digital output timer. Such devices are among the rarest of all Accutron timepieces.
