28800 VPH Watch. What Is It?

The moment you start to learn more about mechanical watches, it is very easy to get lost in the aesthetics: the complicated dials, the artistry of the case, or even the feel of the luxurious straps. However, one of the most endearing features of a mechanical watch remains literally underneath the surface: the movement, precisely the frequency at which that movement works. If you’ve ever heard of a  28,800 VPH watch and you’re wondering what it actually means, then this article is for you. 

In this blog post, we are going to cover everything there is to know about the 28,800 VPH movement: what it is, why it matters, and how it affects the performance of your timepiece.  Whether you are a seasoned watch enthusiast or a beginner collector, getting to understand this key feature can enrich your appreciation for the intricate mechanics of your wristwatch.

What Does VPH Mean In a Watch?

Let's begin with the basics: VPH stands for vibrations per hour, and it basically refers to the number of times the balance wheel inside the watch swings back and forth in an hour. The balance wheel is that very key component that acts like a pendulum in order to regulate the speed at which the movement ticks. 

Each time the balance wheel completes one swing in one direction is considered one vibration. When the balance wheel moves in one direction and returns back to its original position, that is one full oscillation (or two vibrations).

For example, if we say a watch works at 28,800 VPH, it means that in an hour it makes 28,800 vibrations of the balance wheel. Now, to break it down even more, this is 4 Hertz (Hz), since the balance wheel oscillates four times per second and each oscillation counts as two vibrations. The 28,800 VPH is indeed the most common frequency used in modern mechanical wristwatches. 

Why Does VPH Matter?

You may wonder why the number of vibrations per hour is relevant. It's all in a string with the relation of frequency, accuracy, and power reserve.

The higher the VPH, the more accurate the watch tends to be. The reason is that the faster the movement of the balance wheel, the more stable it is, and the less it is susceptible to variations from factors outside it, such as temperature variations, magnetic fields, or even physical shocks. 

In simpler terms, a watch that has a higher VPH is better at keeping the same time and with great accuracy. For instance, if the watch has a frequency of 28,800 VPH, then it would be able to time events down to 1/8th of a second and be more accurate as compared to a lower frequency, say 21,600 VPH or 18,000 VPH; these can time only up to 1/6th and 1/5th of a second, respectively.

The History of High-Frequency Movements

The quest for high-frequency movements has a long history within the circles of horology. In fact, one of the earliest examples can be attributed to  Louis Moinet.  In 1815, he designed the first chronograph with a frequency of 108,000 VPH. While this was a technological marvel at the time, it wasn't until the mid-20th century that high-frequency movements became more common.

In the 1960s and 1970s, several watchmakers began to experiment with higher frequencies. Seiko's Hi-Beat series introduced movements beating at 21,600 VPH, while the famous Zenith El Primero, from 1969, pushed the frequency to 36,000 VPH. The El Primero became an icon of precision and innovation, partly for its frequency but also because it was the very first self-winding chronograph.

Despite such steps forward, it would be well into years later that 28,800 VPH became an industrial standard. More and more watchmakers started to appreciate the fact that 28,800 VPH is a frequency that offers a balance between accuracy and durability. And so today, it has become the most common choice in luxury modern timepieces.

How Does Frequency Affect Watch Performance?

One thing there seems to be consensus on in the horological community is that the higher the frequency, the better the performance. To a large extent, this is the case, but again, with one or two nuanced considerations.

Accuracy:The higher the VPH, the more accurate the watch will be because the wheel has a faster rate of oscillation and can recover itself from external disturbances, like shocks and temperature changes. This makes them highly suitable for chronographs and other complications that need high precision in timekeeping.

Smoothness of the second hand:Amongst the major differences between high and low frequency movements relates to the smoothness of the second hand’s sweep. In a 28,800 VPH watch, the seconds tick along 8 times per second, thus creating a smooth, continuous motion. On watches with a lower frequency, say 21,600 VPH, with only 6 ticks per second, the motion of the second hand would be choppier or even staggered.

Power reserve:As we said earlier, the higher the frequency the more power is consumed. This leads to shorter power reserves compared to watches with lower frequencies. However, modern advancements in movement designs - especially with the introduction of silicon parts inside the mechanism - helped counteract this issue by making high frequency watches efficient without sacrificing too much power.

Is 28,800 VPH The Best Frequency for a Watch?

For most watch enthusiasts, 28,800 VPH offers just the right balance between performance, accuracy, and longevity. It gives sufficient precision for daily applications yet provides a decent power reserve and good durability. Watches that beat at 28,800 VPH are generally popular in the luxury watch industry, making it easier for collectors and watch aficionados to find the timepiece that suits their needs.

That being said, whether 28,800 VPH is the "best" frequency for you is a matter of personal preference. If ultra-high accuracy is more critical to you than infrequent servicing, then you may want to consider a higher frequency watch. Or if you're looking for something with a longer power reserve and less maintenance, you may find that a lower frequency watch may be more suitable for you.

Final Words

The 28,800 VPH movement is not just a number; it is the heart and soul of modern mechanical watches. The fact that it easily guarantees a perfect blend of accuracy, durability, and smoothness makes it the gold standard in the watchmaking industry. 

The next time you purchase a  mechanical watch,  consider its frequency. This may be the last thing you notice while searching for a new timepiece, but it's one of the most important things you should keep in mind when looking for a really good watch.
