Youngtown 12888 Movement for Clock Repair Replacement 19mm (3/4 Inch) Shaft Length 11mm (7/16 Inch) Thread Length.

I had a hard time getting the hands to stay in place, but this appears to be working well, and accurate. I'm using the second hand, which is optional; it's a sweep second hand, and it's quiet (no tick tick tick). That's fine with me!

I bought this to replace the motor on our wall clock. Once I watched a YouTube video on how to take apart the clock and measure the parts (really the hardest part of this whole process), it was really easy to install this. I ended up using the existing clock hands. I thought the measurements were just slightly off from what was stated but they worked fine with our clock.

I bought this to replace a clock movement that quit working. It works well and was an easy replacement on a project clock I made several years ago. It has various hands and a second hand, along with the motor for the movement. The movement is a sweep second instead of a click type, but I really don't miss it. It runs on a AA battery that lasts for several months. I like to watch it run every once in a while, just to make sure it doesn't need a new battery. It was a great deal that I couldn't pass up. I like it so far.

Nice replacement for an old clock that my girlfriend had from Ireland. Had to use the original hands from the old movement due to length. Problem was the hour hand did not fit right on the hour post but I cut a skinny strip of good quality electrical tape and wrapped it around the post and now the hand fits nice and snug. It's been running great for months now. Keeps accurate time.

This was the size mechanism I was looking for. It was easy to install and fix the hands. The time is correct after one month of running.

Installation/replacement was super easy, and having the choice of different time pointers was nice. The original unit finally bit the dust after 10+ years. I like the quiet feature of the second hand's continuous motion. For me, the only challenge was determining the size to order and luckily I got it right the first time.

I purchased the 17/32 inch clock mechanism to replace the original one that came with our tiki tock clock. Because of the depth of the clock, it needs a long "stem" to be able to poke the clock and hold the hands. It was easy to install and worked fine for just a little over 2 years and then died. At first around the 2 year mark it stopped holding time. I thought it was the battery. Replaced it with a new one. Then I thought the hands weren't moving freely enough, but they were still spaced just fine. We took it down, and there was no sound at all that the clock was working, even with another new name brand battery. Real crap shoot out there. There should definitely be a clock mechanism with better craftmanship to last longer than 2 years. The mechanism that came with the tiki tock clock (purchased used off of ebay) lasted 10 years in our ownership and who knows how long with the previous owner. Buy at your own risk. Before I purchase this again will look for another brand, another company and see what is available.

Wanted to use the hands of the nautical themed clock that I had but after ordering two different units that did not come with hands and each shaft hub was wider than what I needed, I ordered this clock movement that came with an assortment of hands. As it turned out, the shaft hub for this clock movement was thinner than the other two units and I was able to use the nautical themed hands that I wanted to use. Shaft length was not a problem with this or the other units I tried, just needed a thinner shaft hub. Clock movement is working correctly.

It is a fluid movement mechanism rather than a tik tok tik tok style of mechanism. Therefore it makes no noise. In the past month it hasn't lost any time that I have noticed.

My beloved clock suddenly died and days of searching later I could not find another one that I liked so I decided to try to replace the mechanism. Searched Amazon and decided I liked this one. A few days later and it arrived. Removed 4 screws and one nut, dropped in the new motor. Replaced the nut, pushed on the hands replaced replaced the screws and after inserting a new battery replaced the clock on the wall. Bingo clock running better than ever..
