Get fit in style
Fitness and style collide with the fashionably cool Fitbit Blaze. On the inside, it’s loaded with features to keep you fit, healthy, and in control. The built-in PurePulse tracking technology provides automatic, continuous heart rate tacking. It connects to your phone's GPS to map your routes and track your activity stats. Plus, it wirelessly syncs automatically to popular smartphones and computers. On the outside, you can switch out bands and frames to match your Fitbit to your activity or outfit. And it features a classic watch face, so it really blends when the occasion calls for it.
With the built-in PurePulse technology, accurately monitor calorie burn, maintain intensity, maximize training, and optimize your health—minus the unruly chest strap.

Fitbit Blaze is sweat, rain and splash proof, but is not swim proof. We recommend taking it off before showering, as it’s best for your skin if the band stays dry and clean.
If Fitbit Blaze gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Give your wrist a rest by taking the band off every now and then, and regularly clean your band and wrist. Learn more >
