I am a senior citizen who has severe rheumatoid arthritis.  I had a beautiful chime wall clock that was key wound.  As a result of my RA I could no longer keep it running, so I donated it to a non-profit organization.  I found this lovely battery operated chime wall clock that is quite similar to the one I could no longer maintain.  I am very pleased with it.  It's very lovely in design and I"m enjoying the sound of chimes once again every hour.  I highly recommend this clock.
