Mechanical watch movement for chronograph, has time-measurement system including regulating element, transmission chain and set of indicators for indicating timed duration, where element comprises tourbillon

摘要

The movement has a time-measurement system (1) including a regulating element (10), a transmission chain (12) and a set of indicators for indicating current time, so that the regulating element regulates the indicators through the transmission chain. The transmission chain is kinematically connected to the regulating element. Another time-measurement system (2) includes a regulating element (20), transmission chain (22) and a set of indicators for indicating timed duration. The latter regulating element comprises a tourbillon i.e. planetary gear.
