TIKROUNDOriginal Youngtown 12888 Pendulum Type Movement Step Clock Accessory Quartz DIY Movement Kits,4mm (5/32 Inch) Maximum Dial Thickness, 13.5mm (17/32 Inch) Total Shaft Length.

Replaced mechanism in a pendulum clock.Item was exactly as described and fitted and worked perfectly

this worked great i need to get my clock back up and running and this worked

Bought to replace original clock works of same brand. I did have to use the original, short pendulum 'extension' as the magnet on this kit's part apparently wasn't as strong (?) and wouldn't reliably swing. Not sure what you'd do if this was purchased as a new install and didn't oscillate, hence the one star delete.

Pendelum does not work, but the clock tells time,

I like most everything about this clock movement except that the pendulum is way too fast and it's swing is too wide to be realistic. If the pendulum was more in-sync with the second hand as in one swing cycle per second or close to it I would have given it a 5 star rating. The photos shows my process for converting a vintage United model No. 385 electric clock to this quartz movement. Had to make the pendulum swing area wider and add some relief for the bottom of the movement. It was till like packing 5lbs in a 1lb bag. lol
