It's also one of the few major differences between the pair, though. And that means the array of sensors is still as good as it gets whichever model you opt for. We've commented in our in-depth reviews that both the Fitbit Sense and Sense 2 are excellent health watches - much more so than they are smartwatches, even. The specs show that the Sense 2 is lighter, we should also say, likely thanks to having a slightly thinner case, but we can't say this is something we've massively noticed during testing.

There's a 1.58-inch AMOLED display, the water resistance rating remains at 5 ATM and the battery life is still around six or seven days.

It's now much easier to access, and, though it doesn't look quite as neat, it makes the Sense 2 a much friendlier device to interact with.Īs we say, it's the same story elsewhere when it comes to the overall design. However, there is one crucial difference - the solid state button from the original Sense, one that was located slightly on the underside of the bezel, has been replaced with a physical button on the Sense 2.
