Review on Mudder High Torque Clock Replacement Movement - 1/2 Inch Max Dial Thickness, 9/10 Inch Total Shaft Length (4/5 inch/20mm Shaft Length, Black) by Steven Brouillard

The device looks great and is easy to install. The second hand works and the minute and hour hands move when the dial is used, but they do not move when running on battery power. The used pointer ticks, but nothing else works, so for me a complete letdown. EDIT I got a quick response from the company regarding possible issues that could be causing the crash. It turned out that I had screwed on the hex nut too tightly and pushed too hard in the axial direction with my second hand. I did the latter because every time I turned the watch over to put the screws into the back, the second hand fell off. With these settings, the clock is now running, so I've changed my original review. I would like to thank the company for its responsiveness.
