What is VPH?
Vibrations per hour (VPH) is a critical measurement in horology, indicating the frequency at which a watch’s balance wheel oscillates. It reflects the heart rate of a mechanical movement, directly influencing the watch’s accuracy, stability, and overall performance.
Common VPH Rates
-
18,000 VPH (2.5 Hz): Found in vintage and traditional watches, this rate offers a visibly distinct ticking motion but lower precision.
-
28,800 VPH (4 Hz): The modern standard for high-performance mechanical movements, balancing accuracy, energy efficiency, and durability.
-
36,000 VPH (5 Hz): Known as a high-beat frequency, this rate ensures superior precision and smoother motion of the second hand but demands advanced materials and regular maintenance due to increased wear.
Why VPH Matters
Higher VPH rates translate to shorter intervals between ticks, allowing the escapement to divide time into finer increments. This results in greater timekeeping accuracy and a more fluid motion of the second hand. However, higher frequencies also impose greater mechanical strain, requiring meticulous craftsmanship and durable components.
