The Casio G-Shock GD350-1CR Digital Watch was engineered for those special secet missions that demand precision and stealth. The countdown timer function has a large, easily identifiable button for direct access and sure operation under the toughest of conditions. The large face of the GD350 is configured to ensure that the countdown timer is easily seen in the dark. A high luminance LED can be configured to light up for one, three, or five seconds, while an Auto Light feature causes the face to illuminate automatically.
