Boxx Jewelers is a business that's just always been there. My whole lifetime and much, much longer. One of the few remaining pieces of downtown Monrovia that was part of my childhood is going out of business.
The clock, I think it's safe to speculate, will stay. It was gifted to the Monrovia Historic Preservation Group who are responsible for maintaining the clock. The clock has also been designated a Historic Landmark.
