Press the lower button to go to the next screen.


The status bar symbolizes how close you are to your set daily calorie target. You can set this daily goal in the VIITA app.

Note: If you are not wearing your VIITA Watch, our intelligent algorithm will recognize and take this into account. The algorithm deactivates the HRV and Micro-Movement measurement technique and uses values from your individual past instead. This ensures that you get accurate information about your calorie consumption even when you are not wearing your VIITA Watch.



Your VIITA automatically calculates the amount of water you need every day and also shows you your current consumption. So you know at any time how much water you have used so far. An example: If the display of your VIITA shows 2.3 liters at 10:00 pm, you should have consumed at least 2.3 liters of water from 00:00 to 10:00 pm.

Big Data

By a multiplicity of data, which VIITA has collected millionfold since 2011, it was possible to develop an algorithm which makes it possible to determine your water consumption very exactly. Already 2% fluid loss leads to a performance deficit of up to 20%. This loss of performance is reflected in many measurable factors.

The following measured data are used to calculate your individual water consumption:

  • Data of the Micro-Movement-Sensor
  • Pulse
  • Heart rate variability
  • Regeneration status
  • Stress course
  • Movement patterns of the last 7 days
  • Sleep duration and quality

Note: If you do not wear your VIITA Watch, our intelligent algorithm will detect and take this into account. The algorithm deactivates the HRV and Micro-Movement measurement technique and uses values from your individual past instead. This ensures that you get accurate information about your water consumption, even when you are not wearing your VIITA Watch.


This screen shows you your current regeneration status. If it is high, you are well regenerated and ready for the next training, but if it is low, you should skip your training.


If this value is high, you are currently exposed to high stress. Not only physical stress but also psychological stress is recognized.


Endurance Training

This screen shows you your current individual training recommendation. This displayed value represents the upper limit of your pulse range. Your training should take place in a heart rate zone below this limit and should not exceed the displayed value.

Strength Training

Your body is not ideally regenerated. Better take a break.


The training is done with relatively little weight. You should do about 15-25 repetitions per exercise and not use more than 50% of your maximum power. You should complete 1-2 sets and take about 90-120 seconds break between each set. For example, if you are able to do a bench press repetition with 100kg, then you should not take more than 50kg for light training.


In normal training your goal is to achieve 8-15 repetitions per set. The intensity should be 60-70% of your maximum (in the example from above this would be 60-70 kg for bench press). Do 2-3 sets per exercise and 1-2 exercises per muscle group with about 60-90 seconds break between sets.


During hard training your goal is to achieve a strong training stimulus. Your goal is to achieve 6-12 repetitions per set. The intensity should be at 70-80% of your maximum (in the example from above this would be 70-80 kg for bench press). Do 2-3 sets per exercise and 2 exercises per muscle group with a 60-90 second break between sets.

Correct warm-up - warming up is extremely important to prevent injuries! Use about 20-30% of your maximum power for warming up and do 10-15 repetitions with this weight before you start the actual training. The warm-up must be done for each muscle group separately and immediately before the exercise

Please note the following:
The training recommendation provides information about what training your body can tolerate based on your general regeneration. If you have a localized muscle soreness, it is possible that this does not or hardly affect your regeneration. In this case we would also advise you against training the affected muscle groups. If you are injured, you should not follow the training recommendations of your VIITA Watch.


You can record all your activities with the multisport function. Your heart rate variability and the duration of your activity are stored. These are stored in the internal memory of your VIITA Hybrid until you synchronize your watch with the VIITA app.

In the VIITA App you can view the exact course of your training sessions. You can see the details in day view as well as in week view.

Press the upper button to start an activity. During an activity the display remains permanently on and shows you the duration of the activity and your current heart rate.

To pause the activity press the upper button.

Press the lower button to save the activity, the upper button to continue the activity.

When you have finished your activity press the lower button to go to the Home screen.


Your VIITA Hybrid HRV is able to display notifications received on your smartphone. It shows you from which service (Facebook, Whatsapp, E-mail etc.) the message comes from and who the sender is.

Press the upper button to read the message, the lower to mark it as read.

Press one of the two buttons to no longer show the call on your VIITA.


Please note:

To use Push Notifications on your Smartwatch you have to allow the display of notifications in the history on your smartphone. You can find out how this works with Apple here. You also need to enable notifications in the VIITA app.

Maintenance and support

Handle the instrument carefully - do not drop it or subject it to shocks.

Under normal circumstances, the watch does not require maintenance. After use, clean the case carefully with a soft, damp cloth or chamois leather.

Use only original VIITA accessories - damage caused by non-original accessories is not covered by the warranty.

Use and storage

  • Use the product at temperatures between -10 °C and 45 °C.
  • The product should be stored in a clean, dry place at temperatures between 10 °C and 30 °C when not in use.
  • Avoid extreme temperature fluctuations.
  • Avoid any kind of shock, whether physical, thermal or other. Such shock could damage the internal and external components of your watch.
  • Keep the case of your VIITA away from sharp and hard objects to prevent scratches.
  • Keep your VIITA and all accessories out of the reach of children - there is a danger of suffocation by small parts.
  • If you don't use your VIITA fully charge it once every 3 months to prevent the battery from draining.

Measure heart rate

    • The blood circulation of the skin, i.e. the amount of blood that flows through the skin, varies from person to person and depending on the environment. Under certain circumstances the VIITA may not be able to provide an accurate heart rate measurement.
    • The technology used in the VIITA is based on the light absorbed by your skin and blood. Any permanent or temporary changes to your skin, such as tattoos, sweat or even hair on your wrist, may affect the measurements.
    • Environmental factors can affect the VIITA's ability to take accurate measurements. For example, water can hinder or change the scattering of light, and cold weather can have an effect on the blood circulation of the skin.
    • In order for the VIITA to provide a measurement of heart rate, it must not slip back and forth. Activities that exert force on the wrist, such as boxing or volleyball, can prevent precise heart rate measurement with the VIITA.

Wear my VIITA right

Your VIITA should sit about one centimeter below the wrist. To ensure that your heart rate is accurately measured, the bracelet should be worn comfortably tight around your wrist.


  • Your VIITA is waterproof to 10 ATM. So you can wear it when washing your hands, swimming, showering or snorkeling. But it is not suitable for diving.
  • Avoid contact with chemicals and chemical products like solvents, detergents, perfume or cosmetics. These can damage the bracelet or case of your watch.
  • Avoid extreme environments (such as saunas or steam baths).

Repair and maintenance

  • Do not repair or attempt to repair or modify your VIITA yourself. Repair and maintenance work not described in this manual should be carried out by qualified technical personnel.
  • Extremely high or low temperatures can shorten the battery life.
  • The water resistance of the watch may also be affected by aging of the material. Therefore, we cannot guarantee water resistance indefinitely.

Clean my VIITA

  1. Clean the glass and housing of your VIITA Active HRV with a lint-free cloth moistened with water.
  2. Rinse the silicone bracelet under running water and clean it thoroughly with hypoallergenic soap.
  3. Dry the silicone bracelet with a soft cloth.

Charge the battery

Your VIITA will last up to 14 (40m models) or 21 (45mm models) days without charging.

To recharge your VIITA, please follow these steps:

  1. Connect the USB end of the charging cable to a power source.
  2. Position your VIITA in the supplied charging cradle. You can read the battery level on the clock display while the battery is charging.

Please note that you can continue to use your VIITA Hybrid HRV even with a flat battery. However, in power saving mode you can only read the time. All functions that require a display can only be used with a charged battery. You have to charge your VIIT Hybrid HRV if you want to record the heart rate.
