The limited edition Isobrite Afterburner Series watches were inspired by the incredible power of the twin afterburners of the F-22 Raptor, not only in shape but also in visible intensity. When the afterburners ignite to thrust the F-22 through the night sky, the exhaust flames light up the night. We have successfully harnessed the power of the afterburners with these incredibly bright watches. Each model features ultra bright T100 tritium markers that will glow for up to 50 years. Plus, the uniquely flat shape of the markers increase the visible surface area making you feel the intensity of the afterburners. To ensure uninterrupted service, the watch is powered by a reliable Swiss Ronda 715Li movement with a 10-year lithium battery. When your adventure involves water, the watch is ready to accompany you diving down to 200 meters. Constructed out of lightweight carbon fiber reinforced polycarbonate and scratch resistant sapphire crystal, the watch weighs in at only 3 ounces. Plus, the included silicone strap provides the utmost in comfort and adaptability. Also comes with the following extras: - a black nylon military-style band with stainless steel hardware - a spring bar pin tool for swapping out bands
