Small hand is 8cm, long hand is 11cm, second-hand is 12cm. Clock box is 5.5 x 5.5 x 1.5cm.
You can easily mount the clockwork on a decorative plate, but the screw shaft determines how thick a plate you can mount it on. The screw shaft requires that the plate has a hole of 8 mm diameter, which you can make using a drill. Place the black ring and the selected plate on top of the clockwork so that the screw shaft protrudes through to the front of the plate. Then add the metal ring and nut and screw them to the top of the plate. Finally, fasten the hands onto the clock one by one and insert an AA battery into the clock.
