The Fitbit Charge 4's display is functional, but much less impressive. Colors are vibrant, and it looks striking even at a low brightness setting. Although the narrow AMOLED display measures just 0.76in on the diagonal, is has a resolution of 124 x 206 pixels, meaning graphics and text are smooth and crisp. The Fitbit Luxe has one of the best screens of any fitness tracker we've tested.

Luxe is slightly smaller, but higher resolution.

Fitbit Charge 4 is monochrome backlit OLED.

The special edition comes with both the silicone band and a woven strap with reflective strands worked into the material. The Charge 4's case and buckle are plastic, and it has a silicone band with a subtle diamond texture.

It's available in a range of dark colors (black, navy blue and deep purple). The Fitbit Charge 4 was released before Fitbit introduced its Biologic Design Language, and has a more angular look. †Premium content and features subject to change.The Fitbit Charge 4 has a more angular design than the Fitbit Luxe, with a plastic case rather than stainless steel (Image credit: Fitbit) If you believe you are experiencing a medical emergency, call emergency services.
