A large LCD shows at-a-glance readouts of the data produced in each mode. A high-performance pressure sensor provides altitude readings up to 10,000 meters and automatic air pressure readings every two hours. Measurement results are displayed graphically, which can be used to predict upcoming weather with reasonable accuracy.
Large function buttons allow to one-push operation of display illumination and altitude measurement. 100-meter water resistance and low-temperature resistance up to -10 °C/14 °F allow these models to be worn in the rain, around water, and just about everywhere else. Functions include World Time, stopwatch, 5 alarms and much more. An aluminum bezel and five screws provide a handsome look of quality.
These models come with a choice of three bands: plastic, cloth, or metal.
