"It used to bo so because the cold contracted tlio metal of tho dolicato balance wheel. Hut now this wheel is mado partly of brass anil partly of steel, like tho compensation pendulum pendu-lum in a clock. These metals havo opposite expansibilities and the result re-sult is that tho balance wheel is always al-ways of the same size and runs with tho samo speed in all kinds of weather weath-er and the cold does not affect it."
