BaselWorld 2003 saw the debut of Opus 3, a truly unique timepiece. Back then, even the most bizarre time displays were unheard of, making this 'digital' watch by Vianney Halter a groundbreaking innovation. It took nearly 8 years to perfect, with the first models only reaching customers in 2011. Crafted in either rose gold or platinum, its rectangular case features six porthole openings, each showing a different colored number. Hours in blue, minutes in black, and date in red, all instantly jump to the correct time - a remarkable feat. And let's not forget the mesmerizing 4-second countdown before the minutes change.
