# Aquastar

> Aquastar is a Swiss professional dive-watch manufacturer founded in Switzerland in 1962 by Frédéric Robert, and Swiss-made ever since. Inventor of the no-decompression bezel (1964 patent) and the skindiver category (1957 Model 60). The brand filed eleven patents between 1957 and 1977 that became the technical foundation of the modern dive watch. Issued to the French Navy. Worn by Jacques Mayol, Philippe Cousteau, and Don Walsh (the watch that reached Challenger Deep, 1960).
