Parmigiani Fleurier, a brand known for its classically-styled watches, has entered the hotly-contested luxury steel sports watch category with a new family of watches called the Tonda GT. This is the latest in a series of sports watches from luxury brands in the last 15-odd months, a list that includes entrants from A. Lange & Söhne, H. Moser & Cie, Czapek, and Chopard among others. The luxury steel sports watch category for years has been dominated by two icons – Patek Philippe’s Nautilus and Audemars Piguet’s Royal Oak. And since both these watches have long waiting lists at retailers because of their supposed scarcity, other luxury brands are now hoping that customers will look at alternatives to the big two.
