- Among the most powerful quartz movements available today, offering reliable performance and strong torque to drive clock hands. - Increased spacing between hour and minute hands reduces risk of contact and improves readability. - Available in two shaft lengths to fit a variety of clock cases and dial depths. - 7/16 inch shaft diameter - American "I" shaft, for standard compatibility with I shaft hands. - Function and performance: designed to deliver precise timekeeping in a compact quartz movement suitable for a range of clock installations. - Compatibility: intended for clocks using an American I shaft with a 7/16" diameter shaft. Use scenarios - Replacing the movement in a large wall clock with heavier or longer hands that require higher torque and clearer hand separation. - Restoring a mantel or desk clock where increased spacing between hour and minute hands enhances readability and avoids interference. - Upgrading a clock that uses an American I shaft, with two shaft lengths available to ensure proper fit and alignment within the case.
