I LOVE wall clocks and this one is perfect! It operates on (2) AA batteries and it even has the basic "click" for time. Hearing a clock is peaceful for me - but it is subtle enough that you don't hear it unless it is perfectly quiet. I also have it mounted perfectly so that it reflects into my  "Starburst Mirror" on the opposite wall. And I can see it from my sofa in my sunk-in living room.
