i put on some decent headphones to listen to this and can tell you that at least on my 8800 movement (and the common ETA 2824-2 in another watch i have), this clip misses some important nuance.
both movements have an audible "twang" of the hairspring at each tick -- you can hear it in this video: https://www.youtube.com/watch?v=lNYCujza8JU. the sound is somewhat different for each watch, since the 8800 has a Si14 hairspring and the cheaper 2824-2 is metal. if you want another rabbit hole: [1]
what's interesting is that if you leave the watches on a hard flat surface, like a table or nightstand, the entire surface amplifies this twang, so you can hear it from several feet away.
