This Smart Buckle turns your classic watch into a handsome fitness tracker

If your grandfather wasn’t too impressed when you swapped the family Seamaster for a plastic fitness band, this could be your ticket to getting back on good terms. The Smart Buckle (from $39) is basically a Fitbit-in-a-watch-clasp, promising to connect to most 20mm watch bands (or its maker’s own silicon and leather straps). It tracks all the usual steps, pace, calories, distance and sleep, and apparently lasts a week on a single charge. It’s also waterproof, should you actually take your sailing watch onto the high seas (or, more likely, get caught in some sideways British rain).

About

Mark's first review for Stuff was the Nokia N-Gage in 2004. Luckily, his career lasted a little longer than the taco phone, and he's been trying to figure out how gadgets fit back into their boxes ever since. While his 'Extreme Mark Wilson' persona was retired following a Microsoft skydiving incident, this means he can often be spotted in the wilds of South West London testing action cams, drones and smartwatches, and occasionally cursing at them.
