RepGuy 108 Posted July 11, 2017 I have always wondered how exactly these work. Do they listen for ticking and measure that way, or do they somehow feel the vibrations or see the movement of the seconds hand to measure accuracy? Share this post Link to post Share on other sites
MarcoF 6 Posted July 11, 2017 I would guess they listen for the ticking. There's a mini bench where you clamp your watch face down Share this post Link to post Share on other sites
Theduke.williams 1,036 Posted July 11, 2017 I have always wondered how exactly these work. Do they listen for ticking and measure that way, or do they somehow feel the vibrations or see the movement of the seconds hand to measure accuracy? Right on the first two counts. wrong on the third - there's no camera. Sound is a vibration in air, that's why sound cannot travel through a vacuum. Transponder hears (or rather feels) the ticking of the watch and analyses the difference between the tick and the tock for amplitude, beat error and frequency - marvelous bit of kit.
