A plain Jane crystal regulator with Miss America trim. Note the Jeweled sash and pendulum. All the jewels are intact and bright. That added touch changes the clock completely.2 piece porcelain dial has tiny hairlines on the 12, which makes them almostimpossible to see. An 11 inch polished brass case, 4 beveled glasses eachwith at least one tiny corner chip. Rarely do I see a corner chip bad enoughto have the glass replaced, but it is a fault I feel obligated to mention.Sometimes it takes a magnifying glass to find them. 8 day movement with halfhour gong strike is running fine. The round movement has a rack andsnail count. The case needs to be cleaned and polished to go along with thegreat jeweled sash and pendulum.
