Garmin has announced a new GPS navigator watch called the Garmin Tactix. 

Garmin says it's inspired by "the requirements of Law Enforcement and Police Special Operations", hence the name.

The Garmin Tactix is a rugged watch, offering 50-metre waterproofing, is shock resistant and with a scratch-resistant display.

It will provide you with GPS information, altitude, barometer and compass data while you're out on tactical operations, or just strolling in the hills in your surplus BDUs and Magnum boots.

In addition, in the US it will be preloaded with tide data, for all those amphibious raids on Californian beaches, as well as Jumpmaster software.

The design reflects the special forces ambitions, coming in a matte black finish with a green backlight, designed to be night-vision friendly. The display is a negative mode LCD, with a black background.

"Tactix packs Garmin's trusted navigation technology into a GPS watch that both soldiers and civilians can rely on," said Dan Bartel, Garmin VP of worldwide sales. "Plus, the preloaded tide data and Jumpmaster software, along with its stealth design, really sets Tactix apart from other wrist worn GPS devices." 

The Garmin Tactix is said to give 50 hours of battery life in UltraTrac mode, 16 hours in full GPS mode, or five weeks if you're just using it as a regular watch.

If you're preparing for Hell Week the Garmin Tactix will also act as your training companion: it's ANT+ compatible so you can create a Bluetooth connection to heart rate monitors, cadence sensors and so on.

The Garmin Tactix will be available in autumn 2013 for $449.99 (£278), but there's no word on UK pricing or release date.
