If you’ve been following NASA’s latest moon mission, you’ve probably seen headlines about everything from the floating iPhone in Artemis II to its advanced toilet system. And it seems like wearable makers are also capitalizing on this hype, with CircuitMess just announcing a quirky gadget.

Meet NASA Artemis Watch 2.0, a new smartwatch that brings a retro-futuristic look.

What’s so cool about this one?

NASA Artemis Watch 2.0 features a transparent rectangular body, and the design is easily the main attraction here. It has that chunky, sci-fi gadget body that looks more like a prop from an old-school space adventure than a polished mainstream wearable.

The Artemis Watch 2.0 has fairly modest hardware that uses an ESP32 microcontroller with Bluetooth support, allowing it to connect to Android phones and iPhones for incoming notifications. It also includes a gyroscope, accelerometer, temperature sensor, and compass.

It is not trying to compete with premium wearables out there, lacking popular health features like a heart rate sensor or SpO2 tracking. So it won’t be replacing your Apple Watch.

Why software is the real star here

What makes the Artemis Watch 2.0 stand out is its open-source firmware. The wearable can customize the software, build new watch faces and apps, access sensor data, and much more. It houses a USB-C port for both charging and data transfer, which makes it feel less like a true smartwatcha nd more like a tiny wearable project device.

Price and availability

CircuitMess just released the NASA Artemis Watch 2.0 on its official online store for $129. The company is even offering free shipping globally. It is not the most advanced smartwatch out there, despite what its look might suggest, but for those who want something more playful and programmable, this is a solid nerdy product.

Nothing might be taking on Meta with its own smart glasses

Viture Pro 2 smart glasses

Nothing has already made a name for itself with smartphones, earbuds, and other accessories that look a little different from everything else on the market. Now, the company may be preparing to add another product category to its lineup: smart glasses.

According to Roland Quandt, who shared the details on Bluesky, Nothing is working on two different types of smart glasses. One will reportedly focus on audio, letting you listen to music and take calls, while the other could offer a built-in camera, ChatGPT integration, and translation features. While Nothing hasn't officially confirmed either product, the leak gives us an early idea of what the company might be planning.

Samsung Health now needs just 3 days of sleep data to coach you toward better sleep

Samsung is making its Sleep Coaching feature easier to access while adding more personalized advice and clearer sleep reports.

Samsung health sleep tracking

Samsung is making it much easier to get started with Sleep Coaching in the Samsung Health app. With its latest update, you only need three days of sleep data from the past two weeks to begin, down from seven days in a month.

I think that’s a welcome change. Sleep Tracking only tells you how you slept, while Sleep Coaching tries to help you build better sleep habits. Lowering the requirement means you reach the more useful feature much sooner.

Fitbit Edge gives me more features, but my money’s still on the Fitbit Air

Fitbit Edge vs Fitbit Air: Sometimes, less really is more

Google Fitbit Edge launched

I'll admit, Google's new Fitbit Edge looks on par with some of the great fitness bands coming out of China. It takes everything I appreciate about traditional Fitbit trackers and wraps it in a sleek design and better polish. You get a 1.34-inch Hybrid OLED display, built-in GPS, ECG support, and a physical button. Google has even made the battery replaceable, something I genuinely appreciate in an era when most wearables become disposable once their batteries deteriorate.

For $179.99, the Edge seems to be reasonably priced too. However, the more I think about what I'd actually want from a fitness tracker, the more I lean towards Google's $99.99 Fitbit Air. Believe it or not, the lack of a display is also the Air's biggest strength.
