The index
*
is located behind
the dial at 12 o’clock.
The changes can be seen
using the scale engraved on
the balance
*
cock through
a cutaway in the dial.
Assembling
the Movement
52
53
Put the prepared case with doors open next to the movement
assembled on the seat-board. Only touch the movement with gloves
on and grasp it only by the bezel
*
and carefully place the seat-board
into the grooves in the boards and push it back to the back of
the case.
Regulating your Mechanical M2
As soon as you have put your Mechanica M2 in
motion and set the exact time, you can begin regulating
*
the clock
so that it keeps the most accurate time possible.
Please Regulate the Escapement only using the Index
The other regulating organs explained in Chapter II »Technology and
Workings of the Mechanica M2« have been pre-regulated in our
factory and should not be altered.
After an observation time of seven days, compare the time display of
your Mechanica M2—the watchmaker calls this the »state
*
«—with
a comparative clock like a radio-controlled specimen. This will give
you the daily rate
*
of the clock, which tells you if it is fast or slow in
comparison to a reference time. At the beginning of the regulation
*
,
your Mechanica M2 will probably show a slight deviation. Don’t
be troubled by this; using the index
*
on the escapement
*
you can
effortlessly adjust your clock.
Suggestion:
At the end of this
book on the fold-out
page you will find a
rate table. You can
fill in the changes in
regulation
*
and thus
more systematically
regulate your
Mechanica M2.
Additionally, the table
on the back of the
fold-out page can be
used to keep track
of the rate
*
precision
of your clock.
Tip:
To regulate the clock,
it is best to touch
the index
*
with the
forefinger behind
the dial while at the
same time watching
the changes on the
index
*
scale from the
front.
Tools
Putting your Mechanica M2 into Motion
Winding the Clock.
◊
Winding key
Compartment (15)
If the escapement
*
already moved flawlessly when tested, you can
now completely wind your clock for the first time. End the winding
process immediately if you notice resistance of the stopworks
*
banking at the Spring barrel
*
.
If the movement was completely void of power reserve, it only takes
3.5 winding revolutions until the Spring barrel
*
is completely
tensioned again. This is enough power for your Mechanica M2 to
continue ticking for seven days.
Setting the Time
Set the clock to the correct time. When doing this, the minute hand
can be moved backward or forward; you may not turn the second
hand.
Now enjoy the ticking
of your Mechanica M2!
Now carefully lay the case on its back on the underlay and secure
the seat-board to the case with the two cylinder-head Allen screws
M5 x 30 and corresponding washers.
Proceed with the regulation carefully and move the index only in very
small steps, otherwise the changes can become too great. After
making the first corrections, please observe the rate of your clock for
a whole week since the rate of a clock driven by mainspring can
balance itself out over the course of a full power reserve. You may
need to regulate a little after the fact as described above.
