Eco-Friendly Packaging, Inside and Out

We know how important the great outdoors is to everyone who picks up an Amazfit T-Rex 3. That's why we made sure to use 100% recyclable materials¹⁸ - free of plastic, and biodegradable - for the packaging.

We've even removed the charging cable from the box, which has allowed us to save 3g of metal and 4.5g of plastic per cable from being used in production processes. Plus, this means you won't have yet another connector cord tangled up and hidden away at home.

While the charging cable is removed, the charging base is still in the packaging - so you can pick up one of your many USB Type-C cables and plug it into the T-Rex 3's charging base.

Easily Change Your Strap

The Amazfit T-Rex 3 comes with a free strap-changing kit, which makes it super easy to replace the standard strap with one of your choosing. Show your love for the great outdoors with the new Amazfit Upcycled Silicone Straps, or check out our full range of straps on our accessories page.

Dive into the Watch Face Store in the Zepp App, and explore over 400 unique watch faces available for download. Pick one that matches your style, or one that populates the home-screen with the data that's important to you.
