Attention:

Never turn the hands of the clock by hand! This may damage the mechanism and is not a warranty case. There is a button on the back of the movement case for setting the hands/time.

When assembling indicators and mechanism , do not use force - the mechanism is made mostly of plastic parts.

Over-tightening the nut to secure the movement to the dial may cause part of the thread to break out of the case. A couple of strips of double-sided tape can help with fixation.

Press the seconds hand onto the shaft just enough so that it does not fall off by gently pulling it.

After assembling the hands, when turning the installation knob, make sure that the hands do not touch each other or touch the dial in any position.

When making watches, take into account the possible deformations of materials (especially when the wood dries or when the humidity in the rooms changes). Providing too little for the mechanism The "place" material can deform the mechanism or even break it.
