Most smartwatches are sold on the premise of convenience. They track your steps, ping you when you get a text, tell you to breathe, and remind you to stand up every hour like a politely nagging coworker strapped to your wrist. I don’t say that as a knock on the category. Convenience is genuinely valuable. But somewhere along the way, the smartwatch conversation became entirely about optimization and lifestyle metrics, and we kind of forgot that the wrist is also a really good place to put something that could keep you alive.

That’s where O-Boy comes in. Developed by Brussels-based design studio Futurewave, O-Boy is a satellite-connected smartwatch built specifically for emergencies in places where mobile networks simply don’t exist. No bars. No Wi-Fi. No backup signal. We’re talking mountains, open ocean, remote job sites, the kind of geography that doesn’t care about your carrier plan. In those environments, O-Boy functions as a direct link to satellite communication, allowing the wearer to transmit an emergency alert regardless of terrestrial infrastructure.

Designer: Futurewave

The premise sounds straightforward enough, but the execution is what makes this project interesting. Getting satellite communication hardware into a compact, wearable form factor is not a small feat. Futurewave brought together product designers, electronics engineers, and antenna specialists to make it work, and rethought the assembly system entirely from how conventional wearables are manufactured. That kind of cross-disciplinary collaboration tends to produce things that actually push the category forward rather than just iterating on what’s already there.

Visually, O-Boy reads as deliberate and utilitarian without being overtly tactical or rugged-for-rugged’s-sake. It doesn’t look like a watch that belongs exclusively to climbers or military personnel, which I think is actually the right call. The moment you design something to look extreme, you narrow your audience to people who already identify with that world. O-Boy appears to be reaching for a broader user: anyone who spends time in remote environments, whether for work or adventure, and wants a layer of safety that their phone simply cannot provide.

I’ll be honest about something. I’ve never been fully convinced that the average smartwatch user needs another notification device. The market is crowded, the differentiation is thin, and most new entries end up competing on specs that only matter to enthusiasts. O-Boy sidesteps that conversation almost entirely. It’s not trying to be the smartest watch. It’s trying to be the one you’d actually want on your wrist when a situation becomes life-or-death. That’s a completely different design brief, and it produces a completely different kind of product.

What I appreciate most is that the project seems to understand its context. Conventional mobile networks cover only a fraction of the Earth’s surface. Vast swaths of ocean, mountain ranges, deserts, and rural work sites exist in a communication dead zone that we collectively don’t think about until something goes wrong. The Apple Watch’s satellite SOS feature hinted at this need, but that capability is baked into a device designed primarily for a very different kind of user, sold at a premium price point and wrapped in a broader ecosystem. O-Boy is positioning itself as something more focused, more purpose-built, and arguably more honest about what it’s actually for.

Does it solve every problem in the wearable safety space? Almost certainly not. Satellite communication latency, subscription models for satellite access, and battery constraints are all real questions that any device in this category has to reckon with. Futurewave hasn’t published exhaustive technical specs publicly, so some of those answers remain open. But as a design concept and a signal of where wearables could be heading, it’s genuinely compelling.

The best design doesn’t ask you to change your habits. It meets you exactly where you are, anticipates the moment things go wrong, and gives you a way through. O-Boy feels like it was built with that thinking at its core. Whether it reaches mass production or stays within niche markets, the conversation it’s starting is one worth having.

Sailors used to carry pocket telescopes. Birdwatchers still carry monoculars. Geologists carry hand lenses. What these instruments share, beyond the obvious optical function, is a deliberate relationship to information: you raise the tool when you choose to engage with it, and the world stays unmediated the rest of the time. That’s actually a pretty sophisticated UX philosophy, and it’s one the entire wearable tech industry has quietly abandoned in favor of always-on overlays, persistent notifications, and the assumption that more access to information is axiomatically better. Yuxuan Hua’s Lens concept is a Silver A’ Design Award winner that makes the counterargument in hardware form.

The concept is a detachable AR smartwatch that splits into two objects: a wrist-worn puck for everyday use and a handheld monocular for AR-enhanced outdoor exploration. The back face of the module houses a dual-lens optical array, a wide camera and LiDAR sensor tucked into a vertical pill recess, while the face doubles as a circular display that overlays navigation prompts, species identification, and star charts over a live feed when held up like a field scope. The band itself is Alpine-loop textile, the lug system simple enough to suggest the module can swap across band styles, and the whole thing comes in at 48mm wide and 68g. The rendering detail is strong: the detached module has the cold, machined look of a quality compass or a classic light meter, the kind of object that rewards handling.

Designer: Yuxuan Hua

Hua interviewed hikers, foragers, and stargazers and found three consistent frustrations: devices were too bulky and fragile for rugged environments, and frequent screen interactions broke the rhythm of being outside. The phone-as-field-guide pattern, pull it out, unlock, navigate to the app, wait for it to load, try to hold it steady while pointing at something, is a sequence of six interruptions where you actually wanted zero. Smart glasses solve the unlock problem but introduce the far more annoying problem of a permanent digital scrim between you and whatever you came outdoors to look at. The monocular is the thing you raise when you want to know something and lower when you don’t, which is precisely how attention works when you’re actually engaged with a landscape.

Most AR concept hardware reaches for science fiction: translucent surfaces, glowing elements, the visual grammar of a prop department. Lens reaches instead for the instrument drawer: the detached module has the proportions and material honesty of a quality compass housing or a Leica light meter, machined aluminum with visible fasteners and a lens array that looks like it belongs in an optician’s toolkit. It doesn’t look like the future. It looks like a very well-made tool, which is a significantly harder design target to hit.

Hua began developing Lens in 2021, during the pandemic, which is useful context. Lockdown-era design projects often reveal what designers actually miss about the physical world when it’s taken away, and what Lens mourns, obliquely, is uninterrupted attention. The whole concept is an argument that the best AR device for outdoor use is one that disappears when you’re not using it, one that earns its presence by staying out of the way until the moment it’s needed, then delivers exactly what the moment requires. Whether the engineering can catch up to that vision, packing AR projection, LiDAR, and a wide-FOV camera into a 68g coin of aluminum, is another question entirely. As a design proposition, it’s already done its job.

Je ne suis pas très montre. Je n’en porte pas, je n’en possède pas… Ce temps qui passe c’est l’angoisse mais je me souviens très bien des montres Pebble qui avec leur écran e-ink tenaient des semaines sur une charge et qui ont carrément démocratisé le concept de smartwatch grand public dès 2012.

Hé bien good news, le fondateur Eric Migicovsky a décidé de les ressusciter sauf que c’est en train de tourner au vinaigre avec les bénévoles qui ont maintenu l’écosystème durant 9 ans.

Pour ceux qui ont raté tout le feuilleton, après la faillite de Pebble en 2016 et le rachat par Fitbit (puis Google), une communauté de passionnés appelée Rebble s’est formée pour sauver les meubles. Ils ont récupéré les données de l’App Store, monté une infrastructure de serveurs, financé des développements… Bref, ils ont maintenu en vie un écosystème que tout le monde avait abandonné.

Puis en janvier 2025, Google a ouvert le code source de PebbleOS et Migicovsky a sauté sur l’occasion et a lancé sa boîte Core Devices en mars pour vendre de nouvelles montres Pebble : La Pebble 2 Duo à 149$ et la Pebble Time 2 à 225$. D’ailleurs, 70% des premières unités ont déjà été livrées. Bref, jusque là, tout va bien.

Sauf que Rebble accuse maintenant Core Devices de piller leur travail sans compensation. Selon ce qu’ils racontent leur blog , Migicovsky aurait “scrapé leurs serveurs” le jour même où il devait les rencontrer pour discuter partenariat. Rebble affirme avoir investi des centaines de milliers de dollars pour maintenir l’App Store et les services backend… et Core voudrait un accès illimité à tout ça pour potentiellement créer un App Store concurrent propriétaire.

La bibliothèque mobile libpebble3 utilisée par l’app Core Devices s’appuie notamment sur du code que Rebble a financé via son programme de subventions. Et c’est pareil pour le portage Bluetooth open source vers PebbleOS puisque c’est Rebble qui a payé les devs. Et bien sûr quand ils demandent un engagement écrit que Core ne créera pas un store concurrent… C’est silence radio.

Migicovsky a ensuite répondu sur son blog perso histoire de se justifier. Il nie tout vol et affirme que 90% du code de libpebble3 a été écrit par Core Devices, et pas par la communauté. Et pour le scraping, il explique qu’il construisait juste une petite webapp pour afficher ses watchfaces préférées et que ça n’a rien téléchargé de substantiel.

Et il contre-attaque en accusant Rebble de vouloir créer un pré-carré bien verrouillé emprisonnant les 13 000 et quelques applications que des développeurs indépendants ont créées. Rebble revendiquerait 100% des données de l’App Store alors qu’ils ne sont que l’hébergeur…

Alors qui croire ? Difficile à dire mais la bonne nouvelle c’est que Core Devices a ouvert les schémas électriques et mécaniques de la Pebble 2 Duo sur GitHub et bientôt, l’installation d’apps se fera via un système de feeds multiples, un peu comme les gestionnaires de paquets open source. Chacun pourra alors choisir son store.

Reste à savoir si les deux camps arriveront à s’entendre puisque Rebble a apparemment fait marche arrière sur certaines revendications, notamment sur la propriété du contenu hébergé. Mais le climat de confiance est sérieusement entamé et pour la communauté qui a bossé durement et gratos pendant 9 ans pour sauver tout écosystème… c’est sûr que ça fait mal de voir le fondateur original débarquer et se servir OKLM.

Après pour ceux d’entre vous qui ont une Pebble ou qui lorgnent sur les nouvelles, surveillez le subreddit r/pebble et le Discord Rebble car c’est là que tout ça se passe.
