Mechanical horological instrument (clock) with balance oscillator and anchor escapement.
Balance oscillations are converted into the rotary movement of gear wheels. The oscillations of the balance are supported by the motor, which serves as a source of mechanical energy.
Main parts of the clock:
· Gear wheels (present time clock and seconds timer)
· Oscillator (balance-helix system)
· Anchor escapement
· Pointer system
· Winding mechanism and time set-up system
· Stop mechanism (balance brake)
· Control devices (winding and stop lever)
