Analysis: where they really differ
The Polar Pacer Pro is a training watch: 41 g, 35 h GPS and wrist-based running power as its signature, at an entry price. The Suunto 9 Peak Pro steps up to the high end with multi-band (40 h), an AMOLED screen and titanium-and-sapphire build. Battery is close; the difference is GPS accuracy in tight mountain terrain and materials. If you train by data and race short-to-mid trail, the Polar gives you almost everything for much less.
