BALL Watch Company SA is an American watch company based in La Chaux-de-Fonds, Switzerland. It was founded in 1891 by Webb C. Ball in Cleveland, Ohio, and is directly linked to the American railroad history. == History == Before the development of railroads across the United States, there was no need for a standardization of time or any real accuracy in time keeping. Each town kept its own local time, based on the position of the sun. When trains began to connect really distant cities, it got problematic and difficult to avoid collisions. Moreover, there was no policy nor standards for the watches used by the railroad employees.〔http://ed.ted.com/lessons/how-did-trains-standardize-time-in-the-united-states-william-heuisler〕 On April 18, 1891, a head-on collision between two trains in Kipton, Ohio resulted in several human deaths. At the time, trains were using the same lines in opposite directions and had to cross each other at defined crossing points. That day, one of the conductors’ watches stopped for four minutes leading to the fatal collision. In order to make train rides safer for travelers and employees of the railroads, Webb C. Ball was designated “Chief Time Inspector” and set up tests and standards for all watches used on the trains. Ball’s criteria of accuracy and reliability were so strict that they later inspired others like the Swiss Official Testing Institute (COSC).〔http://www.ballwatch.com/Newsletter/onlinecatalog/2013_consumer_catalog_ENG/〕〔http://en.worldtempus.com/watch-brand/ball-watch〕〔〔http://luxworldwide.com/a-z-of-companies/b/ball-watch-company/〕〔Jidet, Joël, « A l’heure du rail », ''La Revue Des Montres'', March 2013〕〔Webb C.
