The clock has all the time problem because it loses or gains time in a very short period (like in 2 hours 20 minutes). It is in use all the time except the night time. This means, the clockwork doesn't work steadily. It's second-hand goes normally too fast and it moves unsteadily (if it is gaining time, which is more usual). The problem with the clockwork has been the same since the clock was bought. It seems that the problem is not related to the mechanical characteristics of the watch.}
