To replace the wire inside the balance tube, use Tool

No. 3 (Figure 5). When the balance roller unit has been

remounted, suspend it on the framework. To do this, use Tool

No. 1 to push the wire inside the upper bridge and use Tool

No. 8 (ring) to raise the balance. Use pliers to draw the end of

the wire until banking stem M (Figure 1) lies under lower

bridge P. Insert suspension-wire pin N (Figure 3), press it

down while stretching the wire, give a light blow on the pin

in order to make wire slip and release banking stem from

lower bridge. The lower bridge P (Figure 1) must divide the

space between the two planes of banking stem M equally, the

regulating clamp must be tightened and make sure that the

wire is suspended in the center of the tube. There must be no

twisting or torsion of the wire between the point where it is

attached to the wire sleeve by the pin and the point where it

lies inside the threaded clamp.

Check whether the balance is poised and engages the

escapement. For poising see Page 7. The balance engages

when the impulse pin lies forward while the balance is dead

centre. If this is not the case, turn roller through disk O (Figure

3), after having released the screw of said disk O. Then count

oscillations of balance for 15 minutes. If variation exceeds 1

second, more or less, per 15 minutes, adjust the balance by

adding or lessening oscillating and regulating weights.

1 mm of oscillating weight = 8 seconds per 15 minutes.

1 mm of regulating weight = 4 seconds per 15 minutes.

The two sets of oscillating and regulating weights can be

compared on a very sensitive pair of scales, so that, when set

in place on the balance wheel itself, the latter will not be put

out of poise. As soon as sufficiently accurate timing has been

obtained by adjustment of these sets of weights, the final rating

can be obtained by regulator R (Figures 3 and 6) which allows

for exact determination of the required adjustment:

1 division = 10 seconds per 24 hours

If variation exceeds 50 seconds per 24 hours, adjust for

50 seconds when the regulator is in the middle of its run, by

displacing the latter to left or right; then lock regulator tube

V (Figure 6) with appropriate Tool No. 10 (Figure 5) and pull

regulator in opposite direction (it will turn without modifying

adjustment) and finish adjusting after having freed the

regulator tube.

Then replace base plate and check for good operation of

balance locking mechanism.

Should the movement require overhauling (use Tool No.

7-Movement Holder) we wish to stress that, owing to the

minimum power which is transmitted and the slow movement

mechanism, all wheels and pinions must be cleaned, (not

lubricated) and run perfectly free. The surfaces of rest and

impulse of all runners must be perfectly polished, the pallets

very clean and the locks slight with only a small back lash.

Carefully observe poise of the fork which is suspended

by the two pivots of the pallet staff (like a watch balance on

the poising tool); the fork must be slightly heavier on the

horn side, to secure one complete oscillation per minute. At

rest, the fork must have a perfectly vertical position on the

tool; if not, correct by adding a counterweight as required.

(This slight fault in poise is important for it may prevent good

timing.)

When the movement is remounted, put it back and also

check the good operation of the escapement and the fork. If
