TIKROUND Original Youngtown 12888 Pendulum Clock Movement with 3 Sets of Hands 23 mm (9/10 inches) Shaft Length 15.4 mm (3/5 inch) Thread Length.

Very simple. Battery operated. The description on the page says it does not come with a hook, but you can clearly see a hook in the picture. There was a hook in the package. The entire mechanism is held by a single nut it's pretty simple to put together. Requires a single double A battery that is installed from the rear, so be sure you can access from behind. This is a silent mechanism. It does not chime.

Repaired my old clock. It worked and was fun

It was perfect for my application. Had measured the old ones. These fit exactly. Good price. Good assortment of other maybe necessary parts included.

Great replacement to bring an old broken clock new life. Looks like original. Comes with different length and style hands and I did trim the long second hand to use the style I wanted on the clock I had but no issues. Keeps time well without any loss after months of using it. Highly recommend

works fine
