Non-magnetic Watch Co. of America, American watch manufacture
The Non-magnetic Watch Co. of America existed from 1887 to 1905. She sold a complete series of watches with movements from size 16 with seven jewels to size 18 with 24 jewels. Works from Switzerland, Louis Bornand, and later Jean Jaques Badollet & Cie and Aeby & Landry were used. American results from Elgin, Illinois and Peoria firms were also used. All movements were equipped with an antimagnetic hairspring made of a palladium alloy; Charles Auguste Paillard invented this hairspring.
