"These new winter additions to the G-LIDE series are destined to become timepieces of choice among top winter sports athletes. The main feature of these models is low temperature resistance (-20C/-4F), which make them the perfect choice for snowboarders, back country skiers, and others who seek their adventure in extreme cold. These models are based on the big case 8900 series, and come with an Auto LED ""Super Illuminator"" that allows you to activate the backlight with a flick-of-the-wrist for easy reading under harsh conditions. GLS8900-2 is a digital blue resin watch with black dial and negative LCD."
