Jean d'Eve “Samara”

European Watch Clock and Jewellery Fair 1990 BF 309
“Samara”, Jean d’Eve’s quartz-piloted yet battery-free watch is powered by the wearer’s wrist movements. Its microgenerator (with a diameter of only i mm, the world’s most compact) has proved amazingly efficient, providing the “Samara” with more than ten days’ off-the-wrist reserve power. Called “Micro-Generotor”, the system is protected by more than 20 patents. (JEAN D’EVE “Samara”)
