I have an Accutron 214 and I swear it sounds higher pitched than 360Hz (sounds to my ear higher than A440, which I'm very familiar with). Maybe I'm hearing an overtone?

you could measure it.

using an app with a Fast Fourier Transform (e.g. https://github.com/woheller69/audio-analyzer-for-android ), you can visually compare the sounds of your watches

		I know it is at 360Hz, since it keeps time well.
