PUSH AND PULL
This year marks the 220th anniversary of the tourbillon, which was first created by master watchmaker
Abraham-louis Breguet in the summer of 1801. A mechanism that constantly rotates a watch’s balance wheel, balance spring and escapement while the movement is running, a tourbillon counters the effect of gravity and increases the timepiece’s accuracy. The pictured 18-karat gold pocket chronometer by Breguet was sold by Christie’s auction house in 2014 for an eye-popping US$898,000.
