Most gadgets that want to change your habits arrive with a screen, a dashboard and a stream of notifications about your notifications. Arc has none of that.
It’s a concept bracelet from the Belgian product studio Futurewave, one open curve of solid silver. Set a limit once from your phone, say 30 minutes of scrolling. When you hit it, a small pulse travels through the metal into your wrist. Keep going and it pulses once more. Then it lets you be.

That restraint is our favorite thing about it. Arc doesn’t lock your apps or keep score, and Futurewave says it stores no data. It taps you on the wrist and trusts you with the rest.



The technology is a guest.

The shape is much older than the idea. Arc is a torc, the open-ended ring worn across Iron Age Europe. Instead of studying other wearables, the team looked at rib cages, wishbones and seed pods, chasing a form that looks found rather than designed.

They 3D printed form studies, made prototypes in stainless steel and titanium, then cast the final shell in Argentium silver. No clasp, no hinge, not a single visible component.

Inside, a flexible circuit follows the curve, carrying a low-power Bluetooth chip, a curved 25 mAh battery and a piezoelectric element that makes the pulse.

That’s the part that stuck with us. Luxury is built to last and technology is built to be replaced, so Futurewave designed Arc to outlive its own electronics. When the battery finally gives out, you still have a silver bracelet. More gadgets should plan for their own retirement!
We asked Futurewave if we could try one on, and the answer was a polite not yet. Arc is still a concept, with no price or launch date, and whether two gentle taps can beat an endless feed is anyone’s guess.
We’d wear it anyway. It’s also the second open circle to catch our eye this month, after a 98-foot gold serpent on the High Line. More from the studio on Instagram, and more objects that changed how we live in our visual guide to iconic design.
