Abstract
A movement includes a tourbillion block, a tourbillion unit, and a zero reset mechanism. The tourbillion unit includes a carriage, a balance wheel, and an escape wheel. The balance wheel and the escape wheel are rotationally arranged on the carriage. The carriage is rotationally supported on the tourbillion block. The zero reset mechanism includes a first wheel in engagement with the escape wheel. The movement is switchable between a driving mode and a reset mode. When in the driving mode, the zero reset mechanism is rotationally locked to the tourbillion block. When in the reset mode, the zero reset mechanism is rotatable relative to the tourbillion block.
