Introducing two new color variations of the tough and durable G-Rescue Series, the G7900MS.  The hybrid leather/cloth bands of these models utilize ballistic nylon, a lightweight fabric originally designed for use in flight jackets to enhance their overall toughness.  As with all of the G-Rescue series, these watches are distinguished by their 4-point bezel protection, oversized buttons and tide/moon data.  Low-temperature resistance, shock resistance and 200M water resistance ensure dependable operability in the harshest of conditions.
