The frequency of a watch movement's balance wheel, measured in vibrations per hour (VPH), does indeed play a significant role in its accuracy. Generally, higher frequencies allow for smoother operation and potentially higher accuracy due to the increased number of vibrations.
Watch movements with a frequency of 28,800 VPH (8 beats per second) are quite common and have been widely adopted in the watchmaking industry. They offer a good balance between accuracy, energy efficiency, and durability. Many renowned watch manufacturers have used movements with this frequency in their timepieces.
However, movements with frequencies higher than 28,800 VPH, such as 36,000 VPH (10 beats per second), are less common. There are a few reasons why manufacturers may choose not to utilize higher frequencies:
*Energy Consumption:* Higher frequency movements consume more energy compared to those with lower frequencies. This can lead to reduced power reserve, meaning the watch needs to be wound more frequently or have a larger mainspring barrel, which may affect the size and design of the watch.
*Durability and Serviceability:* The increased vibration frequency can potentially put more stress on the movement's components, leading to faster wear and tear. This might require more frequent servicing, which can be a concern for both manufacturers and consumers.
*Cost and Complexity:* Developing and manufacturing movements with higher frequencies can be more complex and expensive. It may require more precise engineering and finer tolerances, which could drive up production costs and retail prices.
While higher frequency movements offer potential advantages in terms of accuracy and smoothness, watchmakers need to carefully consider these factors before deciding to incorporate them into their timepieces. As a result, movements with frequencies higher than 28,800 VPH are often reserved for specific models or limited editions where the benefits justify the added complexity and cost.
