REAR VIEWS OF NOTE
Armin Strom
MASTERPIECE 1 DUAL
TIME RESONANCE
EVEN FROM THE BACK OF THIS UNUSUAL
59mm x 43.4mm oval titanium case, Armin
Strom’s Masterpiece Dual Time Resonance
looks like no other wristwatch. While on the
front you’d see a dual-time display, a
24-hour dial and two oscillators, from the
back our view underscores that four barrels
power these movements. As they
delightfully unwind simultaneously, they
become synchronized.
As a result of this resonance,
a physical phenomenon, the watch
creates a highly stable time-
keeping rate that heightens
overall precision. Resonance,
a technically difficult (and
hard to regulate) technique
used by only a few other
watchmakers, also means the
watch is more efficient and is less
prone to shock-inflicted error. Indeed, Armin
Strom say that its own laboratory testing has
revealed gains in precision of 15-20% for two
COSC chronometer-level regulated
movements placed in resonance.
Armin Strom says that its Resonant Clutch
Spring (which was initially developed for an
earlier watch called the Armin Strom
Mirrored Force Resonance) can take up to
ten minutes to synchronize the two systems.
To further back its claims regarding the
technology, the CSEM (Centre Suisse
d'Electronique et de Microtechnique) has
officially certified Armin Strom’s resonance
system based on the clutch spring as being a
true system in resonance.
As is evident in this back view, Armin
Strom has underscored its technical
proficiency with an equally impressive high
level of finish on the Caliber 17 ARF bridges
and plates.
The Armin Strom Masterpiece 1 Dual Time
Resonance, pictured here with a titanium
case, is also available with a rose gold and
white gold case. Just this past January
Armin Strom introduced the watch cased in
a clear sapphire case.
