Features a touch-sensitive sapphire crystal that activates various functions including compass, altimeter, thermometer, barometer, chronograph, and alarm. Uses CR1632 battery. The caseback has air-flow cutouts for the barometer/thermometer sensors with a specialized filter that allows air pressure measurement while maintaining 30m water resistance. Notable for being one of the first tactile watch movements.
