I once bought a great clock that unfortunately fell and the glass cover cracked. I was well past my warranty time period and glass repairs weren't covered so I had to look for outside help. It wouldn't be a clock repair mechanic but a glass repair service provider who would be the answer. I found Circle Glass and Mirror Repair and when I inquired, I was happy to be informed that they can repair glass covers on clocks so I took my clock to them. Even better, I found that they can also install plexiglass so I gladly paid for better durability. They also finished in a timely manner and now my clock is good as new and great to go. Thank you.
