Winding
The right winder is for time while the left for the bell. If you don’t want the hourly chime, 
simply don’t wind the left side. The right winder takes about 7 half-turns. There is no need to worry about over-winding as long as it is not forced. If the chime is out of synch with the hour, slowly move the hour hand to the hour matching the chimes. Then use the minute hand to slowly advance to the correct time stopping on the hour to allow the chime to ring.
The clock was serviced in the last 10 years and still keeps accurate time. The clock needs to be on a level surface.
