If your watch stops
Normally if your watch stops, simply winding it
with the crown is enough to start the movement.
However, sometimes the movement does not
start again automatically.
This is because the escapement is
no longer receiving an impulse,
as the impulse-pin and pallet
fork remain fixed in this position
(Fig. 1). No impulse is being sent
to the balance.
Turning the case a few times to turn
the balance is enough to reactivate
it (Fig. 3). This means that the
escapement wheel sends the
necessary impulse to the balance
(Fig. 2).
Winding the watch until the end stop (crown in
position
A
) ensure that the watch functions
correctly during approximately 70 hours.
