Finnish sport instruments maker Suunto has just announced AMBIT, a new watch that combines a GPS, barometric sensor (altimeter), 3D compass and heart monitoring (in combination with a chest strap). 

With the built-in SiRF IV low power GPS chipset, the battery lifetime is said to hold up to 15 hours with continuous GPS tracking and 50 hours with GPS tracking every 1 minute.

The watch is water resistant to 100m. 

AMBIT can be used for training outdoor and indoor and while swimming.

Suunto AMBIT is offered in two colors, black or silver and comes with or without a heart rate belt. It will become globally available in March 2012 in selected outdoor stores and the price is estimated to be between €400 and €500.
