Working as a regular wristwatch, the eCO2 by James Kershaw and Chad Garn is an innovative air-purifier that captures CO2 straight from the atmosphere and provides sanitized air, so you may breathe in fresh air all the time even without putting too much pressure on your respiratory organs. Powered by the kinetic energy, the athletic wristwatch makes use of the CO2 scrubber technology, allowing the users to reduce individual carbon footprints and playing their part in sustaining the environment. The eCO2 not just purifies the air, but it also boasts of a fashionable design, matching the latest trends and technology of wearable timepieces.
