Us Stock Moc-31640 Balance Clock Limited Time 30% Off [7zftUOjV]

⚙Authorized and designed by Nico71.
⚙With a total of 688 premium & rich-in-lustre parts.
⚙Detail: Weighted by a battery box and powered by a Korfhage differential on the pendulum, the clock has a planetary gear on the drive train and another planetary gear on the M motor. A control lever connected to a switch operates the tuner by contacting the end stops. The escapement is an anchor escapement which is easy to set. The clock runs as long as the battery is charged and has a timekeeping accuracy of approximately 1-5 minutes/per day.
⚙Message from the Author:
The remontoire is operated every 5 minutes which may seem low but the angular displacement of the weight is also low comparing to a classic weight and drum system (with meters of rope).
I have used the highest gear ratio I can for having the maximum autonomy and enough torque to operate the escapement. The ratio between the escapement wheel and the minute hand is 5:1 x 5:1 x 5:1 x 3:1 = 375:1. The escapement wheel has 8 teeth, and the tic-tac duration is 1.2sec, therefore for each second which passes, the minute hand moves about : 1 / ( 375 * 8 teeth * 1.2 sec) = 1 : 3600 which is correct. The two wheels on the extremities on the balance arm can be moved to find the correct time of tic-tac. Of course the ratio between minute hand and hours hand is 1:12 made with 12:24 x 12:24 x 8:24 = 12:1
