Battery-operated anniversary pendulum movements are typically small, battery-powered units designed to make the ball pendulum in anniversary clocks spin back and forth. These movements are often used in modern anniversary clocks and operate independently of the timekeeping mechanism. Key Features and Functions: Power Source: These movements are powered by a single AA battery. Mechanism: They utilize an electromagnet to give a pulse to a magnet on the pendulum arm, creating a natural swinging motion. Independent Function: The pendulum movement is separate from the clock's timekeeping mechanism and does not affect it. Battery Life: The pendulum will typically stop swinging when the battery voltage drops below a certain level (e.g., 1.2 volts), serving as a reminder to change the battery. Types: Some movements come with 4-ball pendulums, while others have different pendulum designs, including rotary movements that imitate the rotating 400-day clock weight. Usage and Installation: Mounting: Some movements can be mounted using a fixing nut on the shaft or glued into place. Compatibility: They are designed to be compatible with anniversary style clocks and can often be used to replace or repair existing pendulum movements

• A battery-operated rotary clock movement is a mechanism, typically found in anniversary clocks, that makes a pendulum or other rotating element spin, often independently of the clock's timekeeping mechanism
• It uses a AA battery to power an electromagnet that interacts with a magnet on the pendulum or rotating part, creating the back-and-forth or circular motion.
• Movement Dimensions: 57 x 57 x 16mm, pin length 11.30 mm, and pin width 1.30mm. The length from the flat black surface of the movement to the tip of the pin is 17.80 mm.
• Movement supplied with Silver rotary pendulum. Operates completely independent from the clock movement and is simply glued or screwed into the clock's base.
• The movements are ROHS approved, fully tested, and comes with clear fitting instructions. Movements take 1X AA battery (not included)
