Casio just made its digital ring watch actually wearable for everyone. The company's new G-Shock Nano DWN-5600, launching this November for $94, ditches the awkward spacers from the original model and adds a proper adjustable strap that fits finger sizes from 48mm to 82mm. It's the upgrade that should've been there from day one.
The wearable tech world just got a little more practical. Casio dropped news of its second-generation G-Shock ring watch, and the biggest change isn't about new features - it's about basic wearability. After the original CRW-001's awkward spacer system left smaller-fingered users struggling with fit, the new DWN-5600 finally gets what every watch should have: an adjustable strap.
The timing couldn't be better. Since bringing its digital ring watch to the US last December, Casio has been quietly listening to user feedback. The original's rigid band and included spacers were more engineering compromise than elegant solution. Now the DWN-5600 sports a traditional strap with adjustment holes spanning 48mm to 82mm - finally making this quirky gadget accessible to actual human finger diversity.
Pricing tells an interesting story too. At 14,300 yen (around $94) in Japan and €99.90 ($115) across Europe, the DWN-5600 undercuts its predecessor significantly. That's partly because Casio swapped the metallic finish for a more utilitarian resin construction, fully embracing the G-Shock's rugged DNA. The result trades some of the original's jewelry-like appeal for serious durability credentials.
The functionality remains unchanged from last year's CRW001 - and that's probably the right call. The six-segment LCD displays time, includes a stopwatch and calendar, plus an LED backlight that flashes during alarms. Three tiny side buttons handle mode switching and time setting. It's basic digital watch functionality shrunk down to finger size, nothing more or less.
What's fascinating is Casio's regional rollout strategy. The DWN-5600 is launching simultaneously in Japan, France, Germany, and the Netherlands this November, with US availability still TBD. That suggests the company's treating this as a serious product category rather than a novelty experiment. The original ring watch generated enough buzz - and presumably sales - to justify this more thoughtful iteration.
The 200-meter water resistance rating puts this firmly in serious watch territory. You can shower with it, swim with it, probably wash dishes without worry. The two-year battery life matches what you'd expect from a basic digital watch. Casio recommends professional battery replacement to maintain waterproofing, which makes sense given the engineering challenges of sealing electronics in something this small.
Competitively, Casio is still playing in a market of one. While smartwatch makers have experimented with rings (looking at you, Oura), nobody else is making actual digital timepieces you wear on your finger. The closest competition comes from Samsung's Galaxy Ring or similar health-focused wearables, but those are fundamentally different products serving different needs.
The color options - black, red, and yellow - mirror classic G-Shock aesthetics while keeping manufacturing costs reasonable. This isn't about premium materials or luxury positioning. It's about making a functional, affordable digital watch that happens to go on your finger instead of your wrist.
Industry observers will be watching whether this updated design fixes the original's fit issues enough to drive broader adoption. Ring-based wearables face inherent challenges around comfort, durability, and social acceptance. But if any company can normalize wearing a digital watch on your finger, it's probably Casio - the brand that made calculator watches cool in the 1980s.
The DWN-5600 represents exactly the kind of iterative improvement the ring watch category needs. By fixing the original's most obvious flaw - the inability to properly fit different finger sizes - Casio transforms a novelty gadget into something approaching practical daily wear. At $94, it's positioned as an accessible tech curiosity rather than a luxury statement piece. Whether that's enough to make finger-worn timepieces mainstream remains to be seen, but this adjusted approach gives the concept its best shot yet.
