Tissot Seastar-Quartz

European Watch Clock and Jewellery Fair 1977 BF 332
New Tissot quartz watches boast a new low-consumption movement that extends battery life to up to 3 years. Other attractive features include its magnetic clutch for resetting the hour hand (when changing to summer time for instance) without affecting the other two, and an electronic adjuster to set the watch to the exact second.
