Diet plans reduce. That's the whole point. But the weight loss usually results in an added loss elsewhere: less spontaneity, less fun. Less food, less energy. There are exceptions, though. Where you feel a bit trembly and weird on a wan keto food plan, Michael B. Jordan's watch is alert. Spritely, even. That's because the Piaget Altiplano - a watch that broke world records thanks to a barely-there, 3.65mm waistline - has kept the signature sharpness that made for an industry heavyweight in the first place.

During the 63rd BFI London Film Festival, the Coach frontman opted for the ref. G0A43121, another Altiplano keen to flaunt its newfound figure. Unlike the usual mainline however, Jordan's piece has undergone the most complicated of workouts: the double weighted, cross body crunch mockingly plastered all over your Instagram stories.

But, unlike the local Klitschko-like gym regular, this is an elegant exercise. The watch in question slides a complex, Piaget 900P mechanical hand-wound movement into a slight 18-carat white gold case, and achieves such by moving the hours and minutes display to an off-centred position. The reconfiguration has also proudly exposed the mechanical bridges and wheels for all the world to see (and envy in due course).

What's more, the barrel - a component that houses the mainspring, which in turn is the power source of a mechanical watch - has been suspended. This is important for two reasons. Traditional barrels are usually attached to the bottom side plate. And, in Piaget's case, the movement has been reverse constructed, thus leaving the barrel attached by a single bridge to the side of the dial. Look, we said it was complicated.

And yet, for all its painstaking construction, the watch is far from the over-engineered varnish of a bejewelled arm cannon. That's not really Piaget's bag. Instead, it's about elevated dress watches that lose the brawn, but keep the brains. Let's be honest: the biggest guy in the gym isn't always the strongest.
