Exchange Watch

Hello,

If you purchased your Series 8 within the last 14 days (in the U.S.) you are likely eligible to exchange it for an Ultra.

"Standard Return Policy

There are a few important things to keep in mind when returning a product you purchased online from Apple: 

• You have 14 calendar days to return an item from the date you received it.
• Only items that have been purchased directly from Apple, either online or at an Apple Retail Store, can be returned to Apple. Apple products purchased through other retailers must be returned in accordance with their respective returns and refunds policy.
• Please ensure that the item you're returning is repackaged with all the cords, adapters and documentation that were included when you received it."

"Exchange an item

If you purchased your item from Apple in the U.S., you can take it to any U.S. Apple Store for an exchange. Item exchanges are, of course, subject to in-store product availability. It's a good idea to check if a product is in stock by visiting apple.com and then seeing if it's available for pickup at a store nearby. The only exchange exceptions are personalized items (such as engraved iPad or AirPods) and Macs that have been custom-configured. These items cannot be exchanged in store; they can only be returned and your refund will be issued to the payment method you used on your order (per the guidelines in our Standard Return Policy)."

I hope this helps.

Your name sounds like you may live in India? In which case the 14 day return does not apply due to Indian laws. You cannot exchange it that way.
