My Apple watch is heating and i have got skin burn and apple engineer says it could be perfume or coz i am wearing to tight

Hi

If you experience irritation or discomfort on your skin around or beneath your watch, Apple recommends that you remove your watch and consult a doctor / physician before wearing it again.

Discomfort or skin reactions can be a result of various causes including:

• Allergies (eg to nickel);
• Extended exposure to irritants (eg soap or sweat);
• Environmental factors;
• Wearing the band too tightly or too loosely.

If you still have questions for Apple, I suggest that you continue discussing the issue with them (this is a user-based support community).
