The Oakley D1 is timing technology for the human machine. Developed for the training requirements of professional athletes, a proprietary software engine drives integrated circuitry with the precision of digital calibration. An expanded memory core allows the logic module to store comprehensive timing data. Powered by a true lithium battery, a unique array of liquid crystal diodes maximizes display contrast with the optics of electroluminescence.
