put leather in the center and make the border sticks
A clock in Minecraft is a handheld item, it can't be placed like a decorative block. However what you can do is craft an Item Frame and put that on the wall, then put the clock on the item frame. That way you then have a wall-mounted clock.
use an item frame and put the clock in it, this works with any item, including maps
