Within an ornate grandfather clock, a meticulous watchmaker works under the glow of an antique gas lamp. Using a magnifying loupe and fine tweezers, he makes minute adjustments to a complex mechanism. At the heart is a rotating cage shaped like a delicate filigreed orb, spinning once per minute powered by winding gears. Inside the cage, a balanced wheel oscillates rapidly while an escapement regulates its timing. The tourbillon nullifies the effects of gravity on the accuracy of the clockwork by averaging all positions. Engraved scrollwork and jeweled bearings surround the tourbillon displaying master craftsmanship. As the clock ticks with increased precision, the watchmaker looks on with satisfaction at his life's work - this engineering marvel of horology.
