Featuring a vibrating alarm clock to suddenly and noiselessly awaken you from your slumber, the G-Shock GD-350 has officially been unveiled by Casio Japan. Scheduled to begin hitting retailers on February 28th, 2013, this brand-new G-Shock watch will be available in three color variations upon its release. The options will include a black model with a positive display (GD-350-1JF), a black model with a negative display (GD-350-1BJF) and a gray model with a two-tone display (GD-350-8JF). Aside from the vibrating alarm clock, other high points of the GD-350 include a 1000-hour stopwatch, a 24-hour CDT and a high-capacity cr2032 battery, which is reported to last at least 5 years (without the use of vibrator functions). Retail price will be 13500 Yen ($150 USD).
