Wall-mounted, with screws. Almost unused, so it's in good condition, but there is some minor dirt. Runs on AA batteries. There is some rust because the batteries were left in for a long time. The second hand of the clock has been confirmed to be working. I have not confirmed whether the temperature and other hands move. The temperature was the same as on my phone. Made in Japan. Vintage, analog clock, retro. There is a warranty from the time, although it has expired. Thank you.
