I made myself my clocks, there are five. They were not working. Through this mechanism they have now aquired a second youth. They are very reliable, time is always accurate.
Certainly it is a little expensive accessory, but seems very fragile and the mechanism is noisy. The needles are struggling to stay in place. Especially not touch them once mounted (not even for the household)
This mechanism is not silent! It is even louder than before originally fitted on the clock ... Disappointment ... Not returned because the shipping cost have costed too expensive!
Excellent product _ _ very easy to assemble complete control _ AMAZON received very quickly _ Installation of the mechanism is very easy _ the accessories are perfect
