As Chronoswiss celebrates its 40th anniversary, the Swiss watchmaker is thrilled to unveil two new variants of its groundbreaking Opus model, a timepiece that revolutionized watchmaking when first introduced in 1995 as the world’s inaugural serially-produced self-winding skeletonized chronograph.
Lighter, Brighter, and More Striking Than Ever
The two innovative models now feature cases crafted from grade 5 titanium, delivering unparalleled comfort without compromising versatility. The lightweight material enhances wearing pleasure, perfectly aligning with the modern ethos of mobility and ease. Simultaneously, the new dials in vivid green and blue represent the thoughtful aesthetic evolution this historic timepiece has undergone. CVD-coated for irresistible metallic allure, these colors inject a new vibrancy, revitalizing the watch’s aesthetic appeal.
The Opus has been instrumental in shaping Chronoswiss’s 40-year legacy – a pivotal piece meticulously refined over decades. Its revolutionary design exposed the intricate ballet of cams and levers, captivating imaginations and contributing to the renaissance of traditional watchmaking. Today’s variants are powered by caliber C.741S, a Valjoux-based integrated chronograph movement with galvanic black skeletonized bridges.
“The new Opus Titanium arrives just in time to mark our 40th anniversary. This watch is not just a product; it’s a statement of our relentless pursuit of innovation and our respect for tradition,” states Oliver Ebstein, CEO of Chronoswiss. “Once again, we’re set to wow the world, just as our brand did back in the ’90s.”
