Can I return the band wrist for my apple watch if I don't like it?

Did you buy the watch band separately? For returns & refunds, see:

Returns & Refunds - Shopping Help - Apple

If you bought the watch & band together, you may have too return both. To get a definitive answer us the 'Get Support' link at the top-right corner of this page.

Then for returns & refunds, see:

or simply return it to the store you bought it from.
