The Perpetual rotor is Rolex’s automatic winding mechanism. It enables the watch to be constantly wound by the wrist’s movement. Invented in our workshops, then patented, it was introduced in 1931. In a constant state of unstable equilibrium, the half-moon oscillating weight rotates with every gesture. The energy generated is transferred to the mainspring, which is continually wound, ultimately moving the watch hands. Regularly. Precisely. For though we all seek balance, it is imbalance that drives us to move, perpetually.
