iwatch 3 spa heat test

Hi

You should not wear your Apple Watch in an 103° F hot tub.

Doing so would fall outside of Apple's handling guidelines. Apple advises that:

• Apple Watch is designed for use in ambient temperatures between 32° and 95° F (0° and 35° C).

  Your watch can be damaged and battery life shortened if used outside of this range.

• You should avoid exposing your watch to dramatic changes in temperature or humidity.
• Examples of usage that may affect the water resistance of your watch and should be avoided include wearing it in a sauna or steam room.

Note that using your Apple Watch outside of Apple's handling guidelines may render your watch ineligible for service under warranty, AppleCare+ and/or chargeable repair service.
