[ES]
The Nexus Beam arrives in 2026 as a wrist-worn AI companion that projects a crisp 720p touch interface onto your palm. It's ambitious, but after two weeks of testing, it mostly delivers.
Design and Comfort
At 54 grams, the Beam is lighter than last year's LumaLoop and uses a flexible titanium band. The micro-projector sits flush above the wrist, and the 1.4-inch OLED backup screen handles notifications when projection isn't practical. It's IP68 rated, so rain and workouts are fine. The magnetic charging puck is sturdy but adds a proprietary cable to your bag.
Projection and Display Quality
The projected 720p image reaches up to 32 nits brightness—visible indoors and in shade, though direct sunlight washes it out. The auto-keystone correction is fast, and touch detection on the palm is surprisingly accurate for taps and swipes. Pinch gestures fail occasionally, but a quick reset fixes it.
Performance and AI Features
Powered by the Nova Q2 chip and 4GB RAM, the Beam feels snappy. Real-time translation supports 54 languages and worked well in noisy café tests. The on-device voice assistant summarizes messages, suggests replies, and can run offline routines. Health tracking includes ECG, SpO2, skin temperature, and a new hydration index—accurate against a chest strap within 4%.
Battery and Connectivity
The 410mAh cell lasts about 18 hours with light projection, or 9 hours with mixed use. Heavy projection drops that to 6 hours. Wi-Fi 6E and Bluetooth 5.4 are stable; cellular costs extra. Charging to 80% takes 35 minutes.
Comparison: Nexus Beam vs. LumaLoop 2 vs. PulseRing Air
Feature | Nexus Beam | LumaLoop 2 | PulseRing Air
Projection | 720p palm | none | 480p monochrome
Battery mixed | 9h | 14h | 7h
Translation | 54 langs offline | 30 online | 40 online
Health sensors | ECG, SpO2, temp | HR, SpO2 | HR, temp
Price | $499 | $349 | $299
The LumaLoop 2 lasts longer, but lacks projection and offline translation. The PulseRing Air is cheaper but its tiny monochrome pico projector is a gimmick.
Verdict
The Nexus Beam is the first wrist wearable that makes projection genuinely useful. It's not perfect—outdoor visibility and battery life under heavy projection are weak points—but the offline AI and solid health tracking justify the $499 price for early adopters. If you want a smartwatch that goes beyond a screen, this is the 2026 gadget to beat.
