Abstract

The timepiece movement (1) includes a karussel (4) whose platform carries an escape wheel that cooperates with a balance (7). The platform is driven from the time display mechanism associated with a time-setting mechanism (32). The escape wheel is driven directly from the gear train. In addition to compensating for differences in rate due to gravity, the karussel of the invention proposes a new, complementary role: that of time indicator.
