Turning. Spinning. Rotating. Revolving. These are the words that describe the actions of a tourbillon, the complication that has long been considered watchmakings highest accomplishment. Invented in 1795 by Abraham-Louis Breguet, and patented in Paris in 1801, the function was created not for aesthetic reasons but rather to solve problems associated with the effects of gravity on the precision of a timepiece. Just one look at a tourbillon promises to draw in and fascinate, its small, complex parts in constant motion. This year, Harry Winston rolls out the ultimate in tourbillonsa watch featuring not one but three tourbillon cages, each turning at a different rate around the oscillator and making it, quite possibly, the worlds most accurate mechanical watch.
