A New Tribute, A New Texture.
Building on the foundation laid by the Tribute 1, the Tribute² Aurum Edition pushes the limits of artisanal decoration. More openworked and skeletonised than its predecessor, this edition enhances the architectural presence of the movement while revealing even more of the hand-finished detail that defines the collection.

The Pulse of Independent Watchmaking.
The hand-wound AMW21 movement, developed and manufactured entirely in-house, delivers an impressive 100-hour power reserve.

On the back, the movement reveals a three-quarter bridge with Geneva stripes and circular graining, but it’s the 60° hand-polished bevel that elevates it as a tribute to craftsmanship.

Armin Strom: A fully integrated manufacture
While
Armin Strom is a vertically integrated, complete horological
manufacture, no new watch movement would ever have seen the light of day
were it not for Claude Greisler, who puts ideas such as the one
for the revolutionary Mirrored Force Resonance movement down on paper
before they are transferred to computer-aided design programs to start
modelling the movement. Like so many things at Armin Strom all of this
is done in-house, with the dimensions calculated down to a precision of
one micron to provide the inputs for the machines that will eventually
produce the smallest of components.

At Armin Strom, the
majority of components in the movement, with the exception of the
escapement and balance spring, are produced in-house. Small round
components like screws, pinions and gear wheels are produced by
profile-turning machines, which gradually whittle away long steel or
brass rods from the side to cut teeth or axles. Larger components such
as base plates and bridges are produced from brass on CNC machines,
which are capable of machining along multiple axes consecutively using
different tools for different operations, moving the component using
robotic arms.
Tiny and delicate components, such as smaller
bridges, levers and springs, are produced using wire erosion. This
involves threading a wire that is not much smaller than a human hair
through a tiny hole in the metal. An electrical current running through
the wire reacts with a solution in which the entire working plate is
dipped, thus “eroding” minuscule amounts of the metal. This allows
particularly delicate operations to be carried out while maintaining the
structural integrity of the metal. Armin Strom does not produce any of
its components by stamping because of the stresses that this places on
the metal.
Once the raw components are manufactured, they are
engraved, beveled, polished and decorated with circular graining or
Geneva stripes by hand before moving to the in-house electroplating
department. Here, all steel and brass components are first given a gold
plating before a layer of nickel is added to prevent corrosion and
harden the surface. After cleaning, the parts are then dipped in other
electroplating baths to give them their final color such as rhodium,
ruthenium, or rose gold. It is only thanks to its mastery of
electroplating techniques inside its own workshops that Armin Strom can
allow customers to choose preferred colors for the coating on different
components.
Only then can the individual components of the
movement be passed on to the watchmaker for assembly. After setting the
jewels into the base plate and bridges, the watchmaker adds the gear
train and mainspring. After the escapement and balance wheel are
positioned, the movement finally comes to life…only to be completely
disassembled, cleaned, and dried before being re-assembled and
lubricated. After several days of testing the precision, the watch is
finally ready.
