How many Hertz and ticks per second is a 43,200 BPH watch movement?
⚡ Instant Calculated Answer
A 43,200 BPH mechanical movement operates at exactly 6.0 Hz (6.0 cycles per second) and produces 12 escapement ticks per second, with an oscillation period of 83.33 ms.
6.0 Hz

📐 Mathematical Formula & Step-by-Step Substitution
- Understand that 1 full balance wheel oscillation cycle equals 2 beats (one clockwise tick and one counter-clockwise tock).
- Convert beats per hour to full cycles per hour: 43,200 / 2 = 21,600 cycles/hour.
- Divide by 3,600 seconds per hour to calculate frequency in Hertz: 21,600 / 3,600 = 6.0 Hz.
- Calculate pallet fork impulses (ticks) per second: 43,200 / 3,600 = 12 ticks per second (period T = 83.33 ms).
