Notes The more complicated a timepiece is, the more difficult it is to adjust, particularly as concerns complications such as a chronograph, split-seconds function, and/or a register. The additional wheelwork affects the timepiece's functioning, because of the amount of energy required - but often only sporadically, when, for example, the chronograph is in use - and because of the friction to which the moving parts of the mechanism - levers, springs, etc. - are subjected. It is therefore exceptional to find a timepiece with so many complications and which were submitted to Observatory control.
