With mechanically driven hammers, this quartz movement plays the "bim bam" chime on two tuned chime rods. They sound on the hour, the number of chimes indicating the time of day, as well as chiming once on the half hour, or they can be switched off if preferred.
The movement, with an integrated pendulum drive, operates with or without a pendulum (16" pendulum included). The shaft is 9/16" long and supports minute, hour and second hands. Dimensions (excluding shaft) are 6 1/2" wide by 7" tall by 2" deep.
One D battery is required (not included). Instructions included.
