   Temperature Compensation
   The primary enemy of accuracy is thermal expansion. A rise in temperature causes metal components to expand, lengthening the effective length of the hairspring, which in turn slows the oscillation rate. Marine chronometers address this via the bimetallic compensation curb. This mechanism consists of two strips of metal, typically brass and steel, bonded together. As temperature changes, the differential expansion causes the strip to bend, effectively shortening th…
