The most conspicuous thing about the Suunto Ambit 3's design is its size on the wrist. It stands 15.5mm proud and weighs 80g. The result is, compared to even most GPS watch rivals, problematic.
On my large wrist the GPS module, which extends from the bottom of the watch face, tended to dig in against my bone. On thinner wrists, the watch's size meant it was difficult to get it to sit still comfortably. And it looked ludicrous.
