Fast vs. Slow, Hertz vs. VPH: Frequency Explained

Fast vs. Slow, Hertz vs. VPH: Your Watch’s Frequency Explained
by Ashton Tracy

Vibrations per hour (vph), Hertz (Hz), beats per hour (bph), or train count: no matter what you call it, all watches have it. Well, what is it?

Hertz (Hz) is metric and measured in full cycles per second; vph is traditional and refers to half cycles per hour. To convert Hertz to vph (or vice versa), multiply (or divide by) 7,200: 3,600 (seconds in an hour) x two (half beats).

“Frequency” is most commonly referred to as “vibrations per hour,” though, and refers to how fast the escapement of the watch ticks.

With the lilt of Irish laughter

Every day and in every way

Now forever and ever after."

A good read.
WatchGeeks will go down in watch forum history as the worst watch related site that existed. Trolls, threats, bannings, and owners and sponsors talking out of their collective asses to fleece people out of hard earned money. - Koimaster
