As well as Bluetooth music, the 645 comes with Garmin Pay, which is ideal for that post-workout coffee (or beer, we won't judge). In addition, prospective owners should be wowed by the pretty steel bezel, the first Forerunner to get such a flashy addition. Battery life is always an issue with running watches, and the 645 will last up to seven days on a charge or five hours on GPS.

Garmins always have sturdy build quality and should last you forever, so it's no surprise to see the 645 Music having a pleasing heft. In addition, it's a lot slimmer and tidier than previous iterations, and the steel bezel really does make it look much more elegant than other wearables in its class.

The Garmin Forerunner 645 Music is available for $450, and it comes with either a black or reddish-pink cerise band and will arrive within the next three months. If you're still devoted to that old iPod Shuffle, you can pick up a music-free version that's priced at $400, which comes in black or sandstone.
