4 Amazfit watches are on sale at Best Buy, including the Bip for $60 (Update: Expired)

This is the watch that put Amazfit on the map, and it's long been a personal favorite. With its always-on screen, exceptional battery life, heart-rate monitor and built-in GPS, it's no wonder CNET asked this question in its Amazfit Bip review: "Why can't more smartwatches be like this?"

Originally $200, the Stratos never won as much attention as the Bip -- but it has a lot of fans. That's because in addition to all the usual fitness features, it offers a large, lovely display, a water-resistant design and even onboard storage for your music. Read ZDNet's Stratos review to learn more.

The Verge is essentially the Stratos' plastic cousin, offering most of the same features (including the sideload-able music storage), but with a slightly smaller screen encased in a plastic housing. It does have one extra perk not afforded by the Stratos: built-in Amazon Alexa. That feature relies on your phone, of course, but it's still pretty rare in any smartwatch, let alone one at this price.

For exactly what you'd originally pay for the Bip, the Verge Lite offers a big, beautiful AMOLED screen and up to 20 days of battery life (roughly four times that of the standard Verge). It's a little lighter on overall fitness features, but still offers heart-rate monitoring and GPS. You don't get the onboard music storage or Alexa support. Still, for $80? That's pretty hard to beat.
