Technical information

WHY RUN WITH A HEART RATE WATCH?

Heart rate is measured in BPM (beats per minute). The more intensively you exercise, the faster your heart beats, and the more your BPM increases. As you train, you will learn the best heart rate for you to be able to complete your run without losing your breath. Aim for that rate, and you will be able to run more regularly and more easily.

Fabric strap for greater comfort

Electrodes have been built into the elastic of the fabric strap. The electronic module is attached on the outside of the elastic. As a result, no hard components are in contact with your skin.

It is also possible to remove the module to put the strap in the washing machine. Note: the module is perspiration and rain resistant, but must not be put in the washing machine.

MEASURE THE INTENSITY OF YOUR EXERCISE

Unless you set the manual target zone, the watch automatically indicates the intensity of your effort in real time using your heart rate: very light, light, moderate, hard or very hard workout.

Very light: 50 to 60% of your MHR
Light: 60 to 70% of your MHR
Moderate: 70 to 80% of your MHR
Hard: 80 to 90% of your MHR
Very hard: 90 to 100% of your MHR

RUNNING WITH YOUR HEART RATE TO SET THE PACE

Are you often out of breath at the end of a run? The HR gives you real-time information so that you can adjust your speed and avoid going beyond your limits. When the watch indicates "Weak" intensity, you can run and talk at the same time. In the "Moderate" zone, exercise is more intense, but you shouldn't lose your breath. In the "Difficult" zone, you should be out of breath within a few minutes.

RUNNING WITH YOUR HEART RATE TO BURN FAT

Do you run to stay in shape? The "Weak" zone is particularly useful because it allows you to burn more fat and avoid losing your breath. In fact, in this zone, your body is not under stress. It has time to burn fat properly to turn it into energy for your muscles.

SET YOUR TARGET ZONE

You can set up target zones for better management of your training. A graphic indicator shows you, in real time, whether you are within the target zone you have set up.
The watch allows you to set heart rate target zones (in BPM or %HRmax).

PROGRAM YOUR INTERVAL EXERCISES

With this function, you can set up a full interval training: warmup time, active time, rest time and relax time, number of interval series and rest time between series.

COMPARE YOUR RUNS

The watch gives you a summary of your last 5 runs. For each session, you'll find your run duration, your average heart rate and the number of calories burnt. If you have set a target zone, you can also see the time spent in that zone.

It's a watch too!

The watch also tells the time and date, for everyday use. You can also set an alarm.

Easy to read in the sun and in the dark.

The watch has what is known as a reflective screen. It reflects the surrounding light. The more sun there is, the easier it is to read the screen!
When running in the dark, you can use the backlight button to light your screen.

Can I connect my watch or my strap to my phone?

We chose to use our Bluetooth strap to ensure the best possible connection between the watch and the strap. In real terms, it is therefore possible to contact the strap to any sports application on the market which has a heart rate function. But please note: the strap can only be connected to one device at a time. If it is already connected to a phone, it cannot be connected to a watch.

CAN MY SIGNAL BE DISTURBED BY OTHER HEART RATE MONITORS?

No! The signal of the watch is encrypted. The communication between your watch and your strap is therefore unique, and will not interfered by another heart rate monitor. That said, while your watch is pairing with the strap, it is important to stay away from other heart rate monitor users. Once they are paired, you can use your watch near other users.

HOW IS MY HEART RATE MEASURED?

Your heart rate is measured by the strap worn around your chest. The strap has two electrodes and a transmitter.

When your heart beats, it transmits very weak electric fields. They are detected by the electrodes and sent to your watch via the transmitter on the chest strap.
