Amazon is offering a free $50 Amazon gift card when you preorder the Samsung Galaxy Watch 8. This promotional offer is only running until July 24, ahead of the smartwatch's release on July 25. If you know you want to upgrade, this deal makes a lot of sense. You can spend that $50 gift card on whatever you like, with no fees and no expiration date.

If you want the nicer Samsung Galaxy Watch 8, this one comes with a $100 gift card. Of course, it is also pricier, starting at $499.99.

The company's latest smartwatches look sharp, but the first-of-their-kind health tools could be what makes them most compelling.
