It is very rare, yet possible, that some users may have a reaction to certain materials. This may be due to allergies, environmental factors or prolonged exposure to irritants such as soap or sweat.

  • An allergic reaction to the materials used in the back case of the watch.
  • A photosensitizing medication.
    Note that our watches are in compliance with the photobiological lamps standards (IEC EN 62471).

Notes about wristbands:

Our wristbands are either made of FKM, silicone, leather, recycled PET or stainless steel (Milanese and metal wristbands).

To make sure you have the best experience, we recommend you to follow the tips below:

  • Make sure your wristband is clean and dry, particularly after workouts (running, swimming…). It’s also important to clean the inside of your wristband, especially after the shower.
  • Make sure to let your skin breathe. If you wear your watch all day, do not hesitate to remove it for at least an hour. For instance, you can remove your watch before taking a shower.
  • Make sure your wristband is tight enough while still remaining comfortable. If you experience redness, we recommend you to loosen your wristband a bit.

Your wristband should be cleaned regularly. Moisturizers, soaps, and sweat residues can cause skin irritations. In case of skin irritation, we advise you to get in touch with a dermatologist before you put your watch back on.

If you encounter an issue with your wristband, please check this article.
