Replace the balance carefully into
the movement by tilting the wheel
and inserting first, the movement
side pivot (hairspring side) then,
the dial side pivot into the "V-
conic bearing". Adjust the balance
screw enough to hold the balance in
place . By rotating the balance , insert
the hairspring into the regulator slot
and hairspring wedge pin bracket. Be-
fore
re-pinning the hairspring, make
certain the impulse pin is within the
slot on the fork. Repin the hairspring
making sure that the wedge pin is
straight and true, as any distortion to
the pin could interfere with the
normal "breathing" of the hairspring .
The endshake is now finally adjusted
using caution to apply only minimum
downward pressure to the balance
screw as excessive pressure could
damage the points of the balance
staff .
Inspect
the hairspring to be certain
that it is properly adjusted. As shown
by the diagram, the hairspring should
be positioned central ly within the
hairspring slot .
