For a watch that would impress the most hardcore Navy Seal, look no further than the Tactix Bravo GPS Watch from Garmin. It's not only equipped to track whatever workout you have in mind, it's also prepared to assist you, should you find yourself dropped into a war zone. It tracks elevation data, can mark up to 1,000 waypoints, and even has a mode that acts like a trail of breadcrumbs - guiding you back to your starting point. And it's all achieved with a battery that's built to last from 20 hours to three weeks depending on the mode. It comes packaged in a stainless steel casing with a scratch-resistant sapphire lens that's even readable using night vision goggles. It's hard to imagine a more complete timepiece for your next special ops mission behind enemy lines.
