One Century, Signed.
Legacy since 1536
In 1536, the Woerlen family — of Swiss origin — laid the foundations of a tradition rooted in precision, discipline, and meticulous handwork. This heritage, shaped by the values of alpine artisanship, would echo across centuries.
From generation to generation, this mindset endured — evolving from the humble tools of local trades to the cutting-edge mastery of metal. What began in the hands of Swiss craftsmen grew into a legacy of industrial excellence.
Today, CALIBRE W stands as the emblem of that journey.
A name forged from five centuries of know-how.
Swiss roots. French expertise. Global precision.
What drives us hasn’t changed: the pursuit of perfection, forged by heritage.
CALIBRACIER – 1928
Born from French industrial excellence
Founded in 1928, CALIBRACIER emerged at the heart of the French manufacturing tradition — a workshop entirely dedicated to the art of centerless grinding.
It was a time when machines were mechanical masterpieces, and precision was measured not in numbers, but in touch, sound, and feel.
CALIBRACIER quickly became a trusted name in the metal industry, setting the standard for fine tolerances and perfect finishes.
Nearly 100 years later, that same dedication lives on — refined, expanded, and carried further under the name CALIBRE W.
Microns... A Signature of Mastery
Where human expertise meets mechanical perfection
Reaching a tolerance of 0.005 mm isn’t just a technical feat — it’s a mindset.
It’s the result of decades of refinement, of skilled hands, trained eyes, and machines calibrated to the edge of possibility.
Thanks to its unmatched technology and relentless pursuit of excellence, CALIBRACIER has become the benchmark in premium rods across Europe, standing today as the undisputed leader of this demanding segment.
At CALIBRE W, this level of precision is not an exception — it’s the standard we sign with.
Because in our world, there is no such thing as “close enough.”
100 Years of Quality
