Product features and benefits Accurate, low-power timekeeping: Quartz movement with a silent, sweeping second hand provides precise time and low battery consumption—ideal for clocks where quiet operation and long battery life matter. Customizable chime and volume: A rotary volume knob lets you set the chime loudness to suit the room. Four chime options (one simple strike plus three melodic sequences followed by strikes) give you flexible sound choices. Night silence for undisturbed sleep: The movement defaults to 6:00 after battery insertion and automatically switches to silent mode from 22:00 to 05:59 so hourly chimes won’t disturb nighttime rest. Easy chime setup: Use the “SET” button to adjust the chime hour-by-hour; each press advances the chime by one hour. The hourly chime takes effect starting at the next full hour after setting. Compact, battery-powered and compatible: Designed for battery operation, the movement fits clock cases with a thickness of less than 2.8 cm. Shaft and thread dimensions are specified for compatibility (total shaft length 1.35 cm; threaded length 5.6 cm). Key specifications Movement type: Quartz motor with silent, sweeping movement Power: Battery-operated Chime options: 4 selectable sounds (1 simple, 3 melodic + strikes) Volume control: Rotary knob Default display after battery insertion: 6:00 Automatic mute period: 22:00–05:59 Chime setup: “SET” button advances chime by 1 hour per press; chime starts hourly from the next full hour Dimensions and compatibility: total shaft length 1.35 cm; threaded length 5.6 cm; suitable for clock cases < 2.8 cm thick Material: Components made from aluminium (avoid applying excessive pressure during installation to prevent bending and loss of accuracy) Installation and handling tips Gently press parts into place; excessive force can bend the aluminium components and impair accuracy. Install the battery and check the display (default 6:00) before final assembly. After setting the chime with the “SET” button, allow until the next full hour for the hourly chime to begin. Use the rotary knob to find the optimal volume for the room. Practical use scenarios Bedroom wall clock: Use the automatic night mute (22:00–05:59) and low-volume setting so the hourly chime does not interrupt sleep while retaining accurate time. Living room or hallway clock: Choose a melodic chime and medium volume for a pleasant hourly signal that is audible without being overpowering. Clock repair or DIY clock build: Replace an old movement with this compact, battery-powered unit when your clock case is less than 2.8 cm thick, and follow the installation tip to avoid bending aluminium parts. What makes this movement stand out Combines precise quartz timing, a near-silent sweeping movement, and selectable hourly chimes with adjustable volume and a built-in night mute—offering flexible, low-maintenance performance for repairers, builders, or anyone upgrading a clock. Note Parts are aluminium; do not apply excessive pressure during installation, as bending may reduce movement accuracy.
