We liked Samsung's Gear Fit 2, but it had its limits. You couldn't use it to track your swimming, for starters. It's a good thing, then, that well-known leaker Evan Blass claims to have a training deck detailing a sequel that should be unveiled at Samsung's August 23rd event. The Gear Fit 2 Pro would look much like its predecessor, complete with that tall, curved display, but would include some big design upgrades. Most notably, it would add 5 ATM water resistance and that hoped-for swim tracking -- it'll sync up with the Speedo On app. Accordingly, the Pro switches from a snap-on strap to a watch-like buckle to prevent it from falling off in mid-backstroke.
