Detailed view of the “Swissonic” electronic watches presented in Basle by the Horological Electronic Center (CEH) in the “Future Watchmaking” section, an exhibition dedicated to horological scientific research that will henceforth be held each year as part of the Swiss Watch Fair. These watches, equipped with a calendar, have an 18-carat (left) or a stainless steel case (right) of surprising thinness.
