This clock is for 220v 50Hz. Hour digits only 8AM - 11AM slightly folded upwards, they do not fall vertically while turning, due to Age - See Photo with Digits UP. There is slight few moments not synchronized delay when hour changes fro 00-59. Actually synchronization is good, but the hour digit fall flip "slow motion" at 00-59 transition, with delay due to tension, it is starts falling slow 15 seconds or so, it looks like a delay. Hour flips fell down finally few moments later than 59-00 occurs ... due to age, they move so slow only at this moment of transition. Sometimes hour flips down few seconds earlier that minutes flip at 00-99, it is age related. Alarm is basic zooommm noise ... alarm works perfect, at an set appropriate time, may be few min difference possible ... Keeps perfect time. 14 minutes digit is missing. There is a crack in front plastic glass. Will show on video.
