In the world of haute horlogerie, master watchmaker Bernhard Lederer has once again captured. Our attention with the introduction of the Central Impulse Chronometer ‘InVerto. Building on the success of the award-winning model released in 2021. Bernhard Lederer takes horological innovation to new heights with this latest creation.
The Evolution: Central Impulse Chronometer Model 2.0
A Glimpse into Precision
Differing from its predecessor, the Central Impulse Chronometer ‘InVerto’ boldly showcases its intricate movement on the dial side. Every nuance of Lederer’s breakthrough double impulse escapement, double gear train, and two constant force mechanisms is unveiled with elegance and precision.
A Closer Look at InVerto
Crafted with meticulous attention to detail, the 44 mm x 12.2 mm black DLC treated stainless steel case houses the hand-wound 9018 InVerto Calibre. Comprising 212 components, this caliber operates at a frequency of 3 Hz (21,600 vibrations per hour) and boasts an impressive 42 hours of power reserve.
The Heart of Innovation
Transparent Brilliance
Through a panoramic sapphire crystal, treated with double anti-reflective coating, the InVerto mesmerizes onlookers. The culmination of a decade of research and development is evident in the unique escapement – the core component that regulates timekeeping within the movement.
The Dual Escapement
Lederer’s natural escapement introduces two escapement wheels operating alternately. Each connected to a separate gear train and equipped with its own 10-second remontoir d’égalité. The result? Enhanced chronometer performance, stability throughout the power reserve, and prolonged mechanical longevity.
Precision Redefined
The Remontoir d’égalité
At the heart of this precision lies the remontoir d’égalité, a mechanism that accumulates energy in short intervals. This innovative approach ensures a consistent torque profile, offering precise energy delivery to the balance wheel and maintaining chronometric accuracy.
A Historical Feat
The combination of two remontoires with the escapement marks a historic milestone in watchmaking. Validated by the Besançon Observatory and the COSC (Contrôle Officiel Suisse des Chronomètres). This achievement attests to the exceptional frequency stability and chronometric precision of the InVerto.
A Symphony of Craftsmanship
Aesthetic Mastery
While the visible dual seconds hands are absent, Lederer’s attention to detail is evident on the backside, allowing for COSC certification. The movement, including bridges and mainplate, is finished in black, with components meticulously crafted by hand – satin, sandblasted, and brushed surfaces, polished chamfers, frosted and hand-beveled bridges, circular graining on wheels, and hand-beveled spokes.
In-House Excellence
In a rare feat within the watch industry, all components, including the watch hands, are produced in-house by a team of over 25 skilled artisans at the brand’s workshop in Saint-Blaise.
The Exclusive Elegance
Limited Edition Extravagance
The Bernhard Lederer Central Impulse Chronometer ‘InVerto,’ bearing the reference CIC 9018 InVerto, will be a limited edition of only 18 pieces, each priced at CHF 150,000 (excluding sales taxes). A testament to exclusivity and craftsmanship, this timepiece is set to captivate horology enthusiasts and collectors alike.
In conclusion, the Central Impulse Chronometer ‘InVerto’ not only pushes the boundaries of horological innovation but also stands as a symbol of artisanal mastery. With its avant-garde design and precision engineering, this limited edition timepiece is a true collector’s gem, embodying the spirit of excellence that defines Bernhard Lederer’s legacy in watchmaking.
