Watch, has balance wheel pivotally mounted in cage around rotation axis, and protruding upper surface of annular display units, where rotation axis forms constant and non-zero angle with another rotation axis

摘要

The watch has a case (10) provided with a mirror (16), a frame, and a tourbillion (34) provided with a cage arranged to rotate on the frame around a rotation axis. A balance wheel is pivotally mounted in the cage around another rotation axis. Annular display units, formed of minute display rings (18) and hour display rings (20), surrounding the cage are rotated around the former axis. The balance wheel protrudes an upper surface of the annular display units, where the latter rotation axis forms a constant and non-zero angle with the former rotation axis.
