digital clock apparatus fully parametric as regards it' s construction and functioning
used for many years, without operational problems, on a 24 hour basis. Certainly today
there are more compact recommendations based however the joy of the "operator' from a
certain point and after is that of being able to control all the parameter of
construction.</font><font SIZE="2"></p>
