Armin Strom Mirrored Force Resonance User manual

INSTRUCTIONS FOR USE
Mirrored Force Resonance
Thank you for buying an Armin Strom watch.
With its Mirrored Force Resonance model,
Armin Strom proposes one of the most spec-
tacular and innovative applications of the reso-
nance phenomenon in watchmaking by uniting
two identical and independent movements.
Their two twin balances are joined together by
a spring which causes them to resonate. Oscil-
lating at opposing rhythms, they mutually correct
their rate differences to achieve enhanced preci-
sion.
To guarantee perfect working of your watch for
many years to come, please pay careful attention
to the advice on use set out in these instructions.

WINDING
Your manual mechanical watch must be wound
regularly for it to work properly. To do so, turn
the crown clockwise in position 1. When fully
wound, the watch has a 48h power-reserve.
The two barrels of the Mirrored Force Res-
onance model are fitted with a slip-spring,
which is not locked when the movement is fully
wound. Some thirty turns are needed to wind
the watch fully. You may also check the state of
winding by looking on the back of your watch at
the two barrel springs compressed around their
arbor once the movement has been fully wound
(as illustrated in black on the figure below on the
right).

SETTING THE TIME
Pull the crown out to position 2. Adjust the
hours and minutes by turning the crown for-
wards or backwards. Rapid pressure on the
pushpiece at two o’clock enables the seconds
to be re-initialised and synchronized with a time
signal.
Important: always push the crown back to posi-
tion 1 once the settings have been made.

SYNCHRONISING THE SECONDS
The two seconds indicators of your watch rotate
in opposite directions (clockwise and anti-clock-
wise). Brief pressure on the pushpiece at two
o’clock enables the two seconds indicators to be
reinitialised and synchronised.
Lengthy pressure causes the movements to stop
momentarily. They begin to work again when the
pushpiece is released.
Despite the positive effect of resonance on the
accuracy of your watch, de-indexing of the two
movements is a normal occurrence. They need
some time to enter into resonance and certain
shocks or sudden movements may interfere with
the phenomenon. A short time (not more than
10 minutes) is needed for resonance of the two
oscillators to be restored.
