Bien, estimados camaradas de delirios relojeros. He encontrado el correo prometido, que me envió la propia casa respecto a la precisión de, en este caso, un aquatimer crono. Yo había oído campanas pero no sabia bien donde, ya que lo que realmente dice este señor es que el reloj queda ajustado por la casa en los paramentos de + o - 0/7 segundos día, pero que la vida del usuario, según sea muy activa o pausada, afecta a la precisión del reloj y da consejo de como medir la precisión del mismo para ayudar a que el relojero lo ajuste con corrección etc...Bueno esto es lo que yo entiendo con mi lamentable ingles de 6 de EGB.
Espero que os sirva de utilidad. Por cierto, debajo viene el correo y el teléfono de este amable empleado de la casa madre por si queréis achichárrale a preguntas.
UN SALUDO A TODOS
Dear Mr. Ivan
At first of all allow me to congratulate you to your IWC.
Before an IWC leaves the factory, the movement is tested in five different
positions:
Crown down
Crown left
Crown up
Dial down
Dial up
The movement is adjusted in each of these positions to an average rate of
between 0 and +7 seconds per day.
The rate is also affected by the owner's way of life.
The automatic movement will react differently when the wearer has an
extremely active lifestyle from the way it would with a comparatively quiet
person.
However, any deviation from the tolerances mentioned above is not so much a
question of function as of adjustment and wearing habits.
The first thing you should do now is run the watch in by wearing it every
day. If necessary, the watch should be readjusted after the running-in
period. Mechanical watches need to run for a certain time until they become
stable.
IWC runs in its watches under controlled conditions at the production stage
and checks the rate of the movement is checked using a timing machine and
by observing its behaviour over a certain period of time. This usually
takes place at room temperature and with simulated sequences of movements.
On the wearer's wrist, however, conditions may be completely different,
which would result in a different rate from the one recorded during the
test at the production stage.
Keep an eye on the deviations and note down how fast or slow the watch is
every day. Your record might well look like this:
Date Deviation at 8.15 pm
Note
1 July 0 seconds
watch set at 8.15 pm
2 July + 10 seconds
3 July + 20 seconds
Your watchmaker will then reset your watch on the basis of the information
you provide. In this case, he would set your watch to go about 8 seconds
slower per day.
Under certain circumstances, it may be necessary to repeat this step, but
in the end your watch will be perfectly set to your personal lifestyle.
Mit freundlichen Grüssen,
Sincerely yours,
Christian H. Niemann
