I bought this mechanism to repair a clock and 10 minutes later it was distributed for at least ten years I hope: installation was extremely easy, take some precautions so that the needles do not overlap course Also align the only little glitch ... in my case, the thread was a bit too long for my clock and I added three or four rings for the mechanism to flush the display side; which was a drawback for me can be an advantage for others (fixation plate ...) this mechanism makes no noise, the second hand is not moving in jerks and I also reused my old needles despite Needle games provided but the graphics did not suit me. For the price, not even 4 euros, so do not hesitate especially when we see the price of clocks repairers, who are not more! As always, time delivery
