The fine adjus­t­ment of the Atmos clock offers more lati­tu­de than the ori­gi­nal lever stop. On the rele­vant models, the adjus­ting lever can be rea­li­gned and cent­red by blo­cking the toot­hed ring. Howe­ver, this pro­ce­du­re must not be repea­ted more than 2–3 times, other­wi­se mecha­ni­cal dama­ge to the tor­si­on pen­dulum spring can occur! Cent­ring the adjus­ting lever does not replace exchan­ging the weights; it only ser­ves as a pro­vi­sio­nal fine adjus­t­ment!
Exami­ne the fine regu­la­ti­on and check which model your clock is.
Depen­ding on the clock model, you will now need a fine slot­ted screw­dri­ver or a den­tal pick set from the drugstore.
