Placing the Atmos clock "In-Beat".



	First off, if the clock is running, even if it's fast
or slow, do NOT try to place the clock in beat because being
out of beat will cause the clock not to run at all and it has
nothing to do with it's timing.


        There are actually two things, on the Atmos, that
must be "in-beat".  In-beat means that the tick and tock
occur exactly at the same time interval from each other.
If you listen to a mantel, wall, or grandfather clock you
can hear the evenness of the ticking.  It is this evenness
that we call in-beat.  Unfortunately, on 400-days and the
Atmos, your ear is NOT sensitive enough to hear the
differences in the beat or ticking and must rely on
observation or electronic timers.


	The first are the pallets on the fork.  These pallets
are fictioned fit on the fork, so you can move the fork while
one of the pallets is blocked, usually by the escape wheel,
to place this in beat.  The best method I have found is to
remove the power, movement, and pendulum, along with the
suspension unit and then remount the movement and wind the
mainspring.  If the fork is properly poised and in beat, the
fork will impulse rapidly and will continue to do so.  This
is much like the "flutter" on a 400-day but not as fast.


        The second "in-beat" condition is the roller.  It is
exactly like a 400-day in that the roller must have the same
amount of after swing in both directions.  If not there is a
small screw, which once loosened, allows you to rotate it in
either direction.  Another way to state it is that when the
power is off and the movement is removed, the roller will
come to rest in the center front of the frame facing you.


	I use a two handed process in setting the roller and
gently pull the bottom of the roller slightly down and then
tighten the screw.  This seems to make sure that the impulse
is as strong as it needs to be as the pendulum rotates.


        Both the fork and the pendulum, LeCoultre calls it
the balance, MUST be poised.


	Most of the above is contained in the "Atmos Repair
Notes", which is available from all major suppliers for about
$3.00 or $4.00.


        If any of this causes you concern please be sure to
take or mail the Atmos to someone who knows what he or she is
doing because one slip will cost you the price of an overhaul
anyway.
