First produced in 1953, the resonance drive type, properly called an electronic watch maintains accuracy since it operates at a frequency higher than that customarily used with balance-type watches. When the battery is too weak to operate the tuning fork, the watch simply stops, without deterioration. Power is provided by miniature high-energy-density batteries. ]]></termNote><termCreatedDate>2026-03-30 20:55:26</termCreatedDate><relation><relationType>UF</relationType><termId>31398069</termId><termName>electronic watch</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31398010</termId><termName>watches</termName><termType>PT</termType></relation><relation><relationType>NT</relationType><termId>31398064</termId><termName>digital watches</termName><termType>PT</termType></relation></term>  </Zthes>
