A: The Sunon SL28-6 is designed for standard clock dials with a shaft opening of approximately Φ23.70mm. It is compatible with most wall clocks, mantel clocks, and custom DIY clock projects that use a three-hand movement with a calendar date function. Always verify your dial's shaft hole diameter and hand-shaft fit before installation.
Q: Does the Sunon SL28-6 movement come with clock hands?
A: Yes — the movement includes three clock hands (hour, minute, and seconds). The calendar date wheel is built into the movement itself. A battery (typically AA or AA equivalent) is required but not included.
Q: How do I install the Sunon SL28 replacement quartz movement?
A: Installation is straightforward. Remove the old movement from your clock case, thread the new SL28-6 shaft through the dial hole, secure it with the included nut, attach the hands in order (hour, minute, then seconds), insert a battery, and set the time. The calendar date can be advanced by rotating the setting wheel on the back of the movement.
Q: What is the difference between the 3 color/shaft options?
A: The available options typically correspond to different shaft lengths or finishes to accommodate varying dial thicknesses and aesthetic preferences. Select the option that matches your clock's dial thickness to ensure a proper fit and clean finish on the front face.
