Notes

Louis Bornand The Bornand manufactory was in Geneva and was a father and son business. In 1886 an order was received from the Non-Magnetic Watch Company for 34 watches including 12 complicated watches, these watches had non-magnetic balance springs made by C. A. Paillard. The present watch has a non-magnetic balance spring and is likely to have been one of those ordered in 1886. See: Eugene Fuller, The Non-Magnetic Watch Company : A Chronology, Bulletin of the N.A.W.C.C., Vol. 32/3, No. 266, June 1990, p. 236.
