Let’s face it. Mechanical watches will never be as accurate as cheaper quartz watches, but not all quartz movements can be made. Let’s take a look at what the Longines V.H.P. can do to resist your average quartz movement.
First of all, for those who are wondering ” what does VHP stand for?” It stands for “very high precision”. This should serve as a good indication of the direction of this article and commentary. How precise is it? Very accurate!
Initially, all watches were mechanical and had a set frequency to regulate the speed of the gears in the movement. This frequency was measured in vibrations per hour (VPH) or hertz (Hz). When battery-powered watches were introduced, they used a new watchmaking technology that used a battery and a quartz crystal. The battery sends a small charge to the crystal, which causes it to vibrate and helps regulate the frequency of the watch. The quartz vibrates very quickly and resonates very steadily compared to traditional watches. Depending on the make and model, conventional high frequency beats resonate between 5 Hz (36,000 VPH) and 18 Hz (172,800 VPH).
Quartz crystals, on the other hand, vibrate at 32,768 Hz. Again, this is Hertz, not VPH, which literally translates to 235,929,600 VPH.
This can be compared to the Bugatti supercar, the cheap sedan that left the dust on the highway, only with less quartz movement. And the difference in speed is more comparable to a rocket or light spacecraft. When comparing the speed of the car in the above example with the speed of oscillation or vibration, one could say its accuracy. That said, some battery powered movements are more accurate than others, and today we’re going to focus on a very special quartz watch,replica omega watches uk the Longines Conquest VHP 41mm.Let’s look at how to measure the accuracy of a watch and see how a normal quartz movement will stand up and show the difference compared to the Longines Conquest VHP.
How accurate is a Longines watch? In traditional watchmaking, the accuracy of a mechanical watch is measured using a metric of +/- a certain number of seconds per day. This means that there will be a certain number of seconds off each day. A plus sign means it is running fast, a minus sign means it is running slow. Some lucky high-precision mechanical watches have a time deviation of about -4 / + 6 seconds per day, and these watches often receive a special designation from a third-party laboratory called COSC to provide exceptional accuracy, and this designation is called a chronograph. Many Longines watches are COSC-certified chronographs. However, the basic quartz movement deviates by about +/- 15 seconds per month and about 180 seconds per year. An interesting example of mixing these two types of movements is the Grand Seiko watch with automatic spring drive, which also uses quartz and integrated circuits. However, it is accurate in its own right, but is not necessarily considered a quartz powered timepiece.
