A photo wall clock is a type of clock that incorporates personal photographs into the face of the clock. The clock typically has a frame or border that has spaces for photographs to be inserted, creating a custom and sentimental timepiece. Some photo wall clocks have features such as interchangeable photo frames, so that the photographs can be changed depending on the occasion. They can make great decorative and personalized gifts for special occasions such as weddings, graduations, and birthdays.
