I have made this wall clock by decoupaging to a 4mm (just over 1/8'') plywood base a photograph of the Sun. The photo is printed on professional paper with professional ink. The clock measures 25cm in diameter (9 7/8''), the hands are metal & the clock part is quartz with a non ticking, sweeping movement. It works with 1 AA battery. The clock has an integrated hook, so it can go on your wall straight away.
