TIKROUND Original Youngtown 12888 Pendulum Type Movement Step Clock Accessory Quartz DIY Movement Kits,5/16 Inch Maximum Dial Thickness, 4/5 Inch Total Shaft Length.

The unit was almost an exact replacement for failed “works” in my pendulum wall clock and I was able to use hour and minute hands of my old clock. IMPORTANT NOTE: The pendulum will not function unless the unit is aligned perfectly vertically. My pendulum did not work at first. I was able to hang the clock vertically with the back facing me. I then rotated the unit within the clock body so the pendulum hung precisely in the center. The pendulum now works just fine. This unit saved me from buying a new clock for over $100! I am very pleased with my purchase. We’ll see accurate it keeps time after a few days. UPDATE: After three days use this unit loses about 2 minutes per day so I make an adjustment each morning. This is not a big deal since I so many other devices for accurate time when needed.UPDATE:The unit began to lose more time each day to 12 minutes per day - not acceptable. So I returned the unit for a replacement. The replacement is keeping perfect time for 3 days now and the pendulum is swinging with a greater arc. I am very pleased with the replacement unit.

Simple installation and works great.

Quality design. Easy to assemble. Astheticly pleasing.

worked great and had enough parts to fit most clocks

Works well. Easy to assemble and replace the current motor for my clock.

Brand new battery(multi-swapped), clock and unit perfect level install and pendulum did not continue to swing. 20 inch long pendulum maybe too long… Was too quick to tear up/throw away the box.

Arrived fast good product

Functionally it was everything it was described to be, but it loses time quickly. I replaced the battery with a known new battery and it still lost time. The pendulum swings and the hands move, but as an actual useful clock, it is not.
