3. Purchase date: Record the purchase date of the watch to help confirm the warranty period.

4. Warranty period: Indicate the warranty period of the watch, usually one year.

It is recommended that users keep it properly and provide it to an Apple authorized repair service center when repair or warranty is needed.
