Read the paragraph and choose the most suitable heading from the list:
'Paragraph A: In traditional mechanical clocks, timekeeping accuracy depended upon pendulum length or balance spring tension, both of which were susceptible to thermal expansion and mechanical friction. The introduction of quartz crystal oscillators in 1927 exploited the piezoelectric effect: applying an electrical charge causes quartz to vibrate at an extraordinarily stable frequency of 32,768 cycles per second. This technological breakthrough reduced daily timekeeping drift from several seconds to mere milliseconds.'
