What is actually inside
We would rather name the sensor and the lens material than call it a breakthrough.
Five sensors in a closed band
Three optical sensors and two temperature sensors sit flush against the base of the finger. Because the band is closed and there is no clasp, contact stays consistent through the night.
Charging without a cable hunt
Magnetic contacts align the ring the moment you drop it in the case. Eight to twenty full charges per case depending on the model.
Lens technology you can verify
UV400 across the range. TAC for polarizing, PC for impact, CR-39 and nylon for prescription. We name the material instead of calling it 'premium optical grade'.
