All Timekeepers Are Inaccurate

All Timekeepers Are Inaccurate.

The capacity of a watch for keeping good time is very much governed by its construction and its more or less perfect finish. It cannot be expected of the best horizontal watch that it should always keep good time and even less so of the interior make of machine made watches. The changes of oil, the variation in temperature, the diversity of humidity of atmosphere, all greatly affect the going of a watch. Indeed, it is only the most perfect finish which neutralizes the adverse influences to the greatest degree. As a matter of fact, no watch keeps perfect correct time, and even the best chronometers used in observatories and on board ships must be regulated according to tables which are kept to fix the variations to which all watches are liable.
