Period

This example used 1960s-1980s.

Canada

"Accutron" was first wrist watch approved by Canadian National Railway for use by CN staff. Original owner of this watch Russell Winfield Dickenson [1921-1988], started working for CN c. 1950-51. Mr. Dickenson served as a "brake man" for CN, and was employed as a conductor on GO and VIA trains. [Ref. 1]

Function

To measure and display passage of time in 24-hour period in hours, minutes and seconds.

Technical

Accutron wrist watch was first to employ tuning-fork movement, using a 360 hertz tuning fork to drive a mechanical gear train to turn the hands. Consequently it was unaffected by movement [ie. on the arm of the wearer]. It was for this reason the first wrist watch precise enough to qualify for U.S. railroad certification. The tuning fork Accutron was manufactured 1960- 1977. Unfortunately, in 1969 Seiko began offering the "Astron" wrist watch, featuring the first mass produced quartz movement. Easier and cheaper to manufacture, the "Astron" was as accurate as the "Accutron", but could be sold at a much lower price. [Ref. 2]
