Smart Access to vital information in an instant
The Smart Access feature of this new addition to the Gravity Defier lineup of aviator concept watches provides instant access to vital information no matter where your adventures take you. Simple electronic crown operations let you instantly change the city setting, switch between home time and city time, or access Coordinated Universal Time (UTC). An innovative quick-lock mechanism supports both reliable locking and easy release. The hour, minute and second hands are driven by separate, independent motors, so hands instantly move to the required positions no matter what type of operation you are performing. Other features include TRIPLE G RESIST construction, easy-to-read hands and numerals, and solar-powered multi-band radio-controlled atomic timekeeping.
