Development of the Thin Analog Watch with Smart Phone Link, Tough Solar Powered, and with New Electronic Crown

Abstract

  In a multifunction timepiece, the size of a product generally increases with an increase in functions. On the other hand, there is also a certain demand for smaller and thinner products. Therefore, this time, focusing on miniaturization of wristwatches, we have developed an analog watch equipped with Bluetooth® communication function and radio wave solar function that are both thin and functional.
