You will find that timekeeping is not the only thing that the Garmin Tactix GPS watch is good at, as it will also come with an altimeter, barometer and a 3-axis compass. For those who happen to pick up a US-based Garmin Tactix GPS watch, it will arrive preloaded with tide data, while all the other watches will also include Jumpmaster software. It happens to be waterproof up to 50 meters, boasting a night-vision-friendly green backlight with the ability to track GPS coordinates for up to 50 hours on a single charge of your battery. Of course, it does the timekeeping bit just fine, accompanied by a timer, stopwatch, world clock and alarm functionality. Unfortunately, the Garmin Tactix only arrives in one shade – matte black, where it will arrive later this year for $450. [Press Release]
