This clock was so pretty in the photo but unfortunately, it is too small! The clock face is under 5 inches in diameter and about 6.5 inches including the metal trim. I was planning to put it at a big empty wall in my living room but it's too tiny. Amazon should always put the product dimensions in the description. Still, I'm giving it 4 stars because it is well-made (all metal except the back which is plastic), keeps perfect time and is fairly quiet. I don't hear it most of the time except in the dead of night where I could hear it in my bedroom 20 feet away. If you have a small narrow wall, then this clock would be perfect. I would have kept it if it cost only $20. But $48 is too much for a teeny tiny clock.
FYI, it requires 2 AA batteries.
