Removing Surplus Cement
By LESTER C. MORGAN

Much time is saved in most convenient method of doing things, and here for instance is a simple but very efficient method of removing surplus cement from our every-day crystal jobs.

Keep a small bottle of Acetone handy on your bench at all times, moisten a clean cloth with Acetone and rub crystal and bezal. This cuts the surplus cement, leaving the crystal clean and sparkling.  This method does not apply to all brands of cement, but will be found very efficient with brands of a lacquer base.

Acetone may be purchase from your druggist in one pound bottles at a price of 65c. This amount should last the average watchmaker about six months, being very economical with use.

In 1871 a tower clock in New York City kept perfect time for three days, even though the works had been removed for repairs. Janitors pushed the hands ahead every minute, night and day.
