Hey @Alexanderf82! Regarding any irritation, Samsung recommends the following guidelines:
When you wear your smartwatch for a long time, or do a high-intensity exercise while wearing it, skin irritation may occur due to friction and pressure. If you have worn your smartwatch for a long time, remove the watch from your wrist for several hours.
Skin irritation may occur due to an allergy, environment factors, other factors, or when your skin is exposed to soap or sweat for long periods of time. If irritation occurs, stop using your smartwatch, and wait 2 or 3 days for the symptoms to ease. If the symptoms continue or worsen, immediately contact your doctor.
Make sure your skin is dry before wearing your smartwatch. If you wear a wet smart watch for a long time, your skin may be affected.
If you use your smartwatch in the water, remove any foreign materials from your skin and the watch and dry them thoroughly to prevent skin irritation.
Do not use any accessories except the smartwatch in water.
