The blue and yellow G-Shock G-RESCUE G-7900-2 is usually associated with being an overseas Asian and European model but it is also sold by Amazon.com in the U.S. (Be sure to select Amazon.com as the seller to get the 1-year Casio warranty). The G-7900-2 case has an extra rugged style and is designed for emergency rescue workers with its large glove-friendly buttons and tide and moon graph. The unique colorway will match a variety of outerwear or team colors and provides a refreshing alternative to the standard black-red G-7900-1 (amazon), green G-7900-3 (amazon), and red G-7900A-4 (amazon).
Features include shock resistance, 200-meter water resistance, low temperature resistance (-20°C), flash alert, world time, dual 1/100 second stopwatches with one 5-second countdown auto-start, countdown timer (24 hours), 5 multi-function alarms with 1 snooze alarm, hourly time signal, and auto EL backlight with afterglow (3/5 seconds). The G-7900-2 measures 52.4x 50 x 17.7 millimeters and weighs 68.2 grams.
Another recommended G-RESCUE model is the Tough Solar/Multi-Band 6 version of the 7900, the GW-7900-1 (amazon), which is also sold by Amazon.com.
