The biggest manufacturers take advantage of the Geneva watch fair Watches and Wonders to demonstrate treasures of complexity. Arnaud Chastaingt unveils a musical clock inspired by the atmosphere of sewing workshops.

Panerai is playing the extreme experience card: in addition to presenting on its Geneva stand the Luna Rossa Prada Pirelli sailboat participating in the next edition of the America's Cup. Special mention for the limited edition Ruban Couture de laPremière, with its double wrap strap in printed black leather, like a measuring tape. The watch fair runs until April 15, in Geneva, until the end of the Fashion Week of the time.
