However, these numbers are for identification purposes only.
There are no number tables that I am aware of to cross reference the date of manufacture with the serial number.
The school provided a well-equipped facility for its disabled students, and was a pioneer of "accessibility" with automatic doors and extra-wide elevators.
In about 1958 at the behest of NASA, Bulova applied the Accutron technology to devices which could be used for precision timing on satellites.
Engineers and scientists were unsure if a mechanical timekeeping device would work properly in zero-gravity, so it was desired to have both the reliability and accuracy of the electronic Accutron movement.
* "Joseph Bulova School of Watchmaking Training Manual", 9th edition, pub. In the early 1920s, Bulova constructed an astronomical observatory atop a skyscraper in mid-town Manhattan (at 580 Fifth Avenue) for the accurate measurement of sidereal time.
On the top floor of the Observatory an expert mathematician took readings that were simultaneously recorded on a chronograph located in the lower floors of the building.
