Buyer beware! This is advertised as the heart rate monitor version on the ambit 3 sport. After receiving my initial purchase there was no HR monitor. I called zappos to report this issue and another was immediately sent out. Again, the second watch was missing the hr monitor!

I bought the watch to use for triathlon training but I tend to use it primarily for running and cycling. On occasion I use it for indoor training (functional fitness or climbing) with the heart rate monitor and it serves as a great log for heart rate training.

The Suunto Ambit 3 Sport is the middle of three new Suunto sports watches that offer GPS, heart rate and general activity tracking simultaneously. These watches are powerful, highly configurable and, unlike most on the market, can track your heart rate not just out on the trails, but in the pool...

Tracks GPS; heartrate and daily fitness; Tracks heartrate while swimming; Multi-sport and navigation features

Very bulky/uncomfortable on wrist; Daily fitness summary very limited; Pricey compared with new rivals

SUUNTO has been making "smart" watches long before the word smartwatch was even coined, producing watches with a variety of functions like temperature sensors, digital compass, and a load of other functions for sport and outdoor life enthusiasts.

Multisport tracking, including swimming; heart rate monitor; very good battery life

Pricey
