RESONANCE
Thank you for buying an Armin Strom
watch. To guarantee perfect working of
your watch for many years to come, plea-
se pay careful attention to the advice on
use set out in these instruction
INSTRUCTIONS FOR USE
Resonance is a well-documented pheno-
menon in physics. Two oscillators in close
proximity tend to influence each other and
eventually synchronize.
Back to the 17
th
century, Huygens was the
first to observe the synchronization of
pendulum clocks hanging from a common
wood beam. Since then, the phenome-
non has fascinated many watchmakers. But
resonance has rarely been attempted,
let alone mastered. Most research has ge-
nerally focused on uniting two movements
and adjusting the distance between
their balance wheels.
But with its Resonance concept, Armin
Strom proposes one of the most spec-
tacular and innovative applications of the
resonance phenomenon in watchmaking.
The radical innovation lies in its coupling
mechanism. The twin balances are joined
together by a steel coupling spring. The
tiny vibrations in the spring cause them to
resonate and synchronize. Oscillating at
opposing rhythms, they mutually correct
their rate differences to achieve enhanced
marine chronometer precision and stability
