(Pocket-lint) - Garmin's latest GPS sportswatch is chock-full of features and doubles as a personal trainer. It's the new Forerunner 920XT, and it isn't exactly cheap.

The watch, which has a slim profile and is supposedly 15 per cent lighter and 18 per cent thinner than its predecessor, can record detailed metrics for swimming, cycling, and running. It has a flexible, hinged watch band, high-resolution colour display, and Bluetooth support for pairing.

Garmin said athletes can use something called watch-mode as well as activity tracking features to do everything from monitor steps to track calories. The watch also receives GLONASS signals and GPS signals, ensuring connectivity when in range of a smart device.

That means you can receive notifications from your smart device on the watch, including incoming texts, emails, calls, and reminders. And you'll still receive this stuff should you drop the watch in water, as the new Forerunner has a water rating of 5 ATM4 (water proof for 50 meters).

Speaking of water, swimmers have access to advanced swim metrics. Metrics range from drill logging and recording swim distance to stroke type and stroke count. Swimmers can even track SWOLF scores and set distance and time alerts. The watch also includes two types of rest timers.

Other features are specific to cyclists and running. Cyclists, for instance, can use the watch's built-in altimeter for precise ascent, descent, and gradient data. The Forerunner 920XT is also compatible with ANT+ power meters, including Vector S and the dual-sensing Vector system.

You can even pair the watch to a heart rate monitor. Runners should find that feature particularly useful. In fact Runners should enjoy many of the Forerunner 920XT's features such as the ability to track cadence, vertical oscillation, ground contact time, etc.

The watch even shows a colour gauge to enable comparison between running peers. Other handy tools provided are a metronome, with vibration and audible alerts, as well as guide cadence training and a race predictor based on VO2 max for running. There's also a recovery advisor.

The Forerunner 920XT is available in the following colour combination options: black and blue or red and white. It will cost £389.99 (or £419.99 for the premium heart rate monitor bundle) when it launches in the fourth quarter of 2014.
