Why are pliers, tweezers, and many other horologist's tools so often covered with rust? Every workman knows that the answer may be moist, perspiring hands. Watch parts also are exposed to this annoying cause of rust and many a good repair job is ruined by moisture that is deposited on repair parts from the horologist's perspiring hands.
This problem was solved by a Swiss chemist who developed a soap which the horologist could use in place of ordinary soap and which would keep his hands dry all day. He need only wash his hands twice daily with this soap and they would remain comfortably and safely dry.
Swiss watch factories soon recognized the advantages of supplying this soap to their men. Bulova, Gruen, Longines, Omega, Movado, Tavannes, Patek-Philippe are all using it now in their factories in Switzerland.
An American trade journal recently called the attention of American watchmakers to the merits of this anti-rust soap.
Swartchild & Co., after tests that proved to their satisfaction the unquestionable merit of the soap, obtained from the inventor and manufacturer the exclusive right to distribute the soap in the United States. Every horologist can now avail himself of this excellent protection for his watch parts and also his tools.
