Can I return an Apple Watch if I took off the plastic on the box?

Hi

Subject to its return policies, Apple only accepts products for exchange or refund that have been purchased directly from Apple.

For an Apple Watch that has been purchased directly from Apple, Apple's Standard Return Policy can vary by country, but is typically 14 days, including if the Apple Watch has been unwrapped and tried on.

More information and instructions for returning an item are available here (for the US, for example):

Returns & Refunds - Shopping Help - Apple

If you need help with your return, then contact Apple (in the US, for example):

Contact - How to Contact Us - Apple

If you are in a different country, then check the corresponding page for your location, as the policy may be different.

Other retailers' return policies may also vary.

(Note that you are not talking to Apple here - this is a user-based technical support community).

You have 14 days if you bought in from an Apple Store.

Yes, you got 14 days and if there's no damages.
