#baselworld… 1971. #girardperregaux presents the first quartz wristwatch oscillating at 32,768 Hz, a frequency adopted since then as a universal standard.
The innovative GP-350 movement was equipped with an integrated circuit bringing together the equivalent of 300 transistors within an area equivalent to 5 mm2. Its consumption was reduced to 4 micro-amperes, enabling sufficient battery life. The rate error was reduced to 1 minute per year.
One week to go before Baselworld2014 and … mechanical innovations!
