What to do
- Remove the watch and let the skin air out and fully dry.
- Wash the band with mild soap and water regularly, especially after workouts.
- Loosen the band slightly so air can circulate underneath.
- Switch to a breathable or hypoallergenic band material, such as a perforated silicone or woven fabric band, if irritation continues.

- Apply a fragrance-free moisturizer to the area once it's clean and dry, avoiding use under the band while wet.
