"A proper running watch that brings Garmin's core software to a more accessible price."
The 'Brilliant AMOLED Display' translates to a bright, phone-quality screen that's easy to read, but it's also the primary reason you'll be charging this weekly, unlike older Garmin models that lasted longer on dimmer screens.
New runners or those upgrading from a simple tracker who want Garmin's excellent training software without paying for pro-level hardware. A person who values a bright screen for daily use and accepts the weekly charging trade-off. Anyone who runs with their phone and therefore doesn't need music storage on the watch itself.
Athletes who need the best GPS accuracy in urban canyons or forests should spend more for a multi-band model. Anyone wanting to leave their phone at home will need the more expensive 'Music' version. Users prioritizing maximum battery life should look at Garmin's monochrome MIP-display watches instead.
