Harry Chase Brearley, Time Telling through the Ages
“ The old idea of regarding the watch as a trinket rather than as a timepiece, as an expensive toy rather than as an accurate and necessary mechanism, has come down to us from the days when a watch was ornamented outside, because it could not be really useful within. Even now, in spite of the modern demand for accurate timekeeping, that attitude has not entirely died away, as is shown by the expression "gold watch" and "silver watch." Of course, there are really no such things; there are merely gold and silver cases for steel, brass and nickel watches. ”
