HONORIS I Lagoverde: the essence of time, inspired by the lake
HAUTE-RIVE today unveils a rare creation: HONORIS I Lagoverde.

“Lake Neuchâtel has always been a source of inspiration for me. I like to imagine it was the same for my ancestor Irénée, who saw the same ever-changing landscape from his workshop.”
— Stéphane von Gunten

This piece is a vibrant aesthetic tribute to Lake Neuchâtel. Its white gold dial is finely engraved by hand with stylized waves, then covered with translucent green grand feu enamel that captures the lake’s ever-changing colors, strength, inspiration, and energy.

This unique creation is signed Pierre-Alain Lozeron, a master engraver renowned for his exceptional collaborations, including with Richard Mille. Each dial is a unique piece, shaped by the artist’s hand, and is framed by a carefully proportioned 18ct white gold case with a slim profile — despite the immense barrel spring it contains.

An in-house, hand-wound movement powers the watch and delivers an exceptional 1000-hour (41-day) power reserve, made possible by a mainspring over 3 metres long — nearly four times longer than a traditional spring.

Winding is performed via the rotating bezel, using a disengaging mechanism and winding differential — a HAUTE-RIVE innovation. The 288-component movement is largely hand-decorated (satin brushing, anglage, circular graining), and features a flying mystery tourbillon at 6 o’clock, appearing to rise from the dial in visual dialogue with the majestic Wheel of Time at 12 o’clock.

This remarkable movement is currently patent pending, underlining its technical originality and innovative construction.
