Photovoltaic cells were invented in the 1940s, and Patek Philippe produced a novel clock that used them. Once integrated circuit technology improved enough to build a quartz watch, American inventor Roger Riehl created the first solar-powered watch. His Synchronar paved the way for the solar digital watches that brought the technology to the masses in the 1970s. Then there was Uranus, with their wild calculator watch!
Beuchat Envers ACW, Juvenia Contresens, and Klokers: The History of the Anti-Clockwise Watch
Almost all clocks turn “clockwise”, with the hands moving from the top of the dial to the right. But for the last few decades a few oddball watches have used hands moving in the other direction! This corner of horology is not well understood, so I decided to take a stab at documenting this revolution. It begins conceptually with the digital mechanical watches of the 1970s. Then Beuchat, a fashionable French brand of the 1980s, produces the first such watch. Swiss quartz behemoth Ronda pitches in, bringing forth an odd watch from the venerable house of Juvenia before today’s Klokers gets it right.
