Unique 3-Step Testing
  Each clock at Chicago Lighthouse Industries is 100% inspected on the production line for damaged, loose or bent hands, hand alignment, and damaged dials or bodies before the crystal is assembled. |
 Once the clock moves off the production line, the clocks are hung on functional test boards where they are tested against a Master Clock for 12 Hours and given a second 100% visual check by Quality Control for scratches, foreign material, and other visual defects. |
 Thirteen clocks are randomly selected from 1,000 to 2,000 finished products and tested against the atomic clock in Colorado for a period of 72 hours. If any clock loses more than one second, movements are discarded and the entire lot is totally rebuilt. |
