Listen to your rolexes.

[Island-Life]

I have 3 rolexes from 3 different eras. 1973, 2001, and now 2021.

I like listening to The Movement by putting the watch right up to my ear. My 2001 Sea-Dweller makes a completely different sound than my new datejust and of course the 70s Manual wind watch is also completely different.
As they go around in a minute, they each make about three or four very distinct different sound that change about every 15 seconds.

I like listening to the movement now and then and hearing the different tones that they each make throughout a minute.
Try it on your different movements
