摘要

PROBLEM TO BE SOLVED: To provide a biaxial tourbillon for minimizing a variation in clock rate regardless of adjusted position of a clock. SOLUTION: The tourbillon is provided with a first cage (A) containing a balance wheel (10) and an escape pinion (11). The cage (A) revolves around an axis (A1) matching with an axis of the balance wheel. Also this cage (A) is encased in a second cage (B) revolving around a swivel (A2) perpendicular to the axis (A1).
