I have been looking for a good deal on a suunto d4 for a while and whilst searching found the oceanic geo 2.0, both stylish DCs and wearable as a watch, I've been leaning towards the oceanic only for the fact it's more to my budget, however I am worried about its seemingly short battery life. If I wore it all the time as a DC and a watch, can someone shed some light on just how much battery it would chew through compared to say the d4? Or would it be better just to bite the bullet and spend the extra on the suunto in the first place??
