Ever listened to your watches ticking?

I listen to them at times. I can tell the Hz or VPH by counting how many cliks per second. Fun little exercise.

I've been able to confirm so far:

- 18,000 vph in my Longines pocket watch (2.5 Hz or 5 clicks per second),
- 21,600 in my NH35 based divers (3 Hz or 6 clicks),
- 25,200 vph in my co-axial 2500 ETA based (3.5 Hz or 7 clicks).
- 28,800 vph in my regular ETA based and Rolex watches (4 Hz or 8 clicks).

Love the different sound signatures too. Find it pretty fascinating.
