In early 1888, the newly reorganized Non-Magnetic Watch Company of America gained momentum as people became convinced that magnetism was a danger to conventional timepieces. Houston, Journal of the Franklin Institute, March 1888 Pictured: Excerpt from “Paillard’s Non-Magnetic Compensating Balance and Hair-Spring for Watches” by Prof. One of the watches was then taken to the Brush Electric Light Station in Philadelphia for more intense testing.

Houston, March 1888 Journal of the Franklin Institute “The fact, that under these extraordinary conditions, the watch neither suffered any very appreciable variation in its rate, nor had its adjustment seriously affected, shows the extent of the protection afforded by the Paillard palladium alloys.”Edwin J. Kelly and Edwin Corry, representing the firm of Bailey, Banks & Biddle, skillfully rated the watches before and after the experiments, comparing them with time signals from the United States Naval Observatory.įollowing the initial experiments, Houston concluded that the watches produced by the Non-Magentic Watch Company were immune to the effects of magnetism, stating: Houston published a comprehensive article exploring several experiments conducted on two Non-Magnetic Watch Company movements.Īfter testing the general effects of magnetism on the hairspring and balance, Houston turned to experiments to evaluate the timekeeping properties of the watches under the influence of magnetism using powerful dynamos.
