Analysis: where they really differ
Two high-end watches with maps, multi-band GPS, onboard music and titanium, picking opposite sides on the display. The Coros Apex 2 Pro uses transflective MIP and squeezes out 66 h of GPS (26 h multi-band) with 21 days of smartwatch use; it's the watch for anyone who wants battery to spare and a simple interface. The Garmin FR965 goes for a bright AMOLED, a far more complete ecosystem of metrics and features (Training Readiness, heatmaps, Garmin Pay, more integrations) and 31 h of GPS. Both weigh the same (53 g) and navigate equally well. In short: the Apex 2 Pro gives more battery and less complexity for less money; the FR965 gives the best screen and the deepest software.
Choose the Coros Apex 2 Pro if…
- You want 66 h of GPS and to not charge the watch all week
- You prefer a simple interface and the sunlight readability of a MIP screen
- You want a high-end mapping watch for less
Choose the Garmin Forerunner 965 if…
- You want the brightest AMOLED display and the most complete training software
- You use Garmin Pay, heatmaps and the Garmin ecosystem integrations
- 31 h of GPS is enough and you prioritise metrics over battery
