What sets this running watch apart from most others?

It is waterproof. That makes it really great for triathletes who need to rapidly transition from running to biking to swimming.  This also has all the connectivity you need to beam data using a wireless link to your computer so that you can track performance.

Move from water to bike with ease
After a swim you can easily and quickly switch the watch from its wrist mount onto a bike mount (optional quick release fitting) without upsetting your data collection.
You can also connect to a foot pod or cadence sensor as well as a heart rate monitor so you are tracking just about all the variables you can.
