Only available from Hammacher Schlemmer, this is the watch that achieves precise time using both atomic timekeeping and GPS technology. It’s updated six times a day by the nearest world atomic clock transmitter and uses GPS technology to automatically adjust its time according to zone and daylight savings, ensuring accurate time no matter where you are in the world. A resin case secures the watch and a scratch-resistant, non-reflective sapphire crystal protects the 2 1/4"-diameter face. Six electro-mechanic motors operate the hands, chronograph (1/20th second accuracy), world time, 24-hour time, latitude and longitude indicators, and its classic date display. Its rechargeable battery stores energy collected by a solar cell in the watch’s face and provides up to six months of use on a full charge. Water-resistant down to 656'. With an LED light and an 8 1/2"-long adjustable carbon fiber band that secures with buckle.
