Ever listened to your watches ticking?

[Vetracer]

Most posts are visual and I admit, this is a geeky observation but I think an interesting one nonetheless. I accidentally started comparing the ticking sound of the watches in my collection and discovered that each watch of the same model ticked with the same sound. Is this possibly a good way of verifying authenticity?

I'm not an expert horologist but I wonder if watch movements have a signature pattern which a timograph could be used to compare.

I wonder how many of you having read this will be placing your watches against your ear listening to their movements
