FREQUENTLY ASKED QUESTIONS
How does Frederique Constant Analytics work?
Frederique Constant Analytics is composed of a clip with a microphone that measures the sound signal generated by the mechanical movement of the watch. The application analyses the sound signal and can tell the precision of the watch.
Does Frederique Constant Analytics work on Quartz watches?
Frederique Constant Analytics only works with mechanical watches.
Does Frederique Constant Analytics work with my smartphone?
Frederique Constant Analytics application was developed for iOS and Android platforms. However, some smartphones may not be compatible with the application or the clip. Please check the supported devices list.
Do I need an internet connection to use Frederique Constant Analytics?
You need an internet connection to authenticate the clip serial number, to create a Frederique Constant Analytics cloud account, to back-up and restore measurements.
To perform measurements on watches, you don’t need an internet connection.
Why should I create a Frederique Constant Analytics cloud account?
The first time you launch the application, you need to create a cloud account in order to authenticate the serial number of your clip.
Then you can use your cloud account to log in and use the application.
On your cloud account, you will be able to store your watch measurements. Thus, you can keep track of the behavior of a watch. If you change phone, you can restore all your data.
What happens with my Frederique Constant Analytics cloud data?
Your data is securely stored on your cloud account, hosted and backed-up in Switzerland and remains anonymous.
Can I use my Frederique Constant Analytics clip on several phones?
With your Frederique Constant Analytics cloud account credentials, you can log in the application on several smartphones.
What can I do if the measurements are not satisfying?
Please check the Troubleshooting page.
What is the effect of a Noisy Environment?
Frederique Constant Analytics is designed to be extremely sensitive to sound, especially to high-frequency sound. Finding a quiet place helps a lot to get a reliable result.
What is the Measurement Time?
The measuring time is how long Hairspring takes to calculate the precision. The shorter the measuring time is, the faster the result will come out, but with a lower accuracy. The longer the measuring time is, the slower the result will come out, but with a higher accuracy. Usually, a measuring time of 30s is enough to get a ±1s/day accuracy. Tap the settings button to set the measuring time and the watch’s frequency.
Why is a longer Measurement Time better?
A longer measuring time helps to get a more accurate result, it is more likely to be affected by noises, which means if a noise goes into the system, it will affect the result for longer time if we choose a longer measuring time. In a noisy environment, a shorter measuring time helps to get a more reliable result, though with less accuracy.
What is the Oscilloscope?
The oscilloscope shows the waveform of the signal, with a length of exactly 1 second. It will automatically amplify the signal to a proper amplitude for easy observation. The frequency of the watch can be calculated from the oscilloscope. For example, if there are 6 tick-tocks in 1 second, the watch’s frequency = 6 * 60 * 60 = 21600 (VPH). The noise level can also be told from the oscilloscope. The wave height shows the level of noise.
Which Frequencies are supported?
Frederique Constant Analytics supports wide range of frequencies:
- 14,400 VPH
- 16,200 VPH
- 18,000 VPH
- 19,800 VPH
- 21,600 VPH
- 23,400 VPH
- 25,200 VPH
- 28,800 VPH
- 36,000 VPH
What is the Lift Angle?
Lift Angle is the angle the balance passes through while interacting with the pallet fork. Most modern watches have a lift angle of 52 degrees. Generally lift angles range from 44 to 58 degrees. The are exceptions, for instance the Omega Co-Axial movement angle is 30 degrees. Along with the Rate, Lift Angle is the second required information in analyzing the performance of a watch movement. Given those, Analytics can calculate balance wheel Amplitude and Beat Error.
What is the Beat Error ?
Beat Error shows how equal each swing of the balance wheel oscillation is. It is the amount of time by which the duration of swing differs from one side to the other in the oscillation of a balance wheel. Its value is calculated by subtracting the duration of the second vibration from the duration of the first vibration.
- Excellent : 0.0 – 0.5 milliseconds
- Acceptable : 0.6 – 1 milliseconds
What is Amplitude?
The measure of the amount of rotation in the swing of the balance wheel, in either direction. Amplitude is higher when a watch is lying flat and usually falls when the watch is in a vertical position, due to increased friction. Amplitude can also fall as the watch winds down and the mainspring delivers less power.
Amplitude is a good indicator of the movements health and if is too high or too low, or that changes too much in different positions, can indicate a problem with the movement.
- Excellent: 270-310 degrees
- Acceptable: 250-270 degrees
What is the Rate?
Rate shows how fast/slow the watch runs in seconds per day. This is the most basic statistic and will at least let you know how accurate your watch is. If your watch is COSC certified, in order to be in good health it needs to be running between -4 and +6 seconds per day. Otherwise it will depend somewhat on the watch, but with a few exceptions you should consider the following to be a good range of your movement’s health:
- Excellent: +/- 7 s/d
- Acceptable: +/- 20 s/d
What means Beats per Hour (BPH)?
The top-line statistic when describing a mechanical watch movement is the BPH. In other words, the number of times the balance wheel will swing half a rotation over the course of sixty minutes. This relates directly to Beats per Second:
- 14,400 bph = 4 beats per second
- 18,000 bph = 5 beats per second
- 21,600 bph = 6 beats per second
- 28,800 bph = 8 beats per second
- 36,600 bph = 10 beats per second
