In our heart-rate tests, the Forerunner 245 performed slightly better than the Pace 2, though it struggled a bit in our tests (a separate chest strap can help bolster precision).

It has a less robust battery life than the Coros Pace 2. It uses a quintet of buttons (our other top pick, the Coros Pace 2, has a digital dial and one button), and its interface is easy to navigate. The Forerunner 245 is customizable, from its on-the-run data screens to watch faces. We like the Garmin Forerunner 245 for runners who want a trustworthy, traditional running watch with enhanced smartwatch features (notifications, the ability to sync to a calendar, local weather) that make all-day wear appealing. But if those extras aren’t critical for you, the Pace 2’s run-specific metrics-including power (which can help inform running efficiency and evaluate workout intensity) and a no-fuss function and feel-deliver lots of value. The Pace 2 shows notifications of your choice, but it doesn’t offer other smartphone features, like onboard music capabilities or the ability to sync to your calendar or local weather report.

It offers 16 activity modes, including indoor run and track run (though no trail option, which the Forerunner 245 has). The watch did a good job of tracking our daily step counts.

The Pace 2 stumbled when it came to heart-rate tracking (to improve accuracy, it can be paired with a heart-rate strap). Instead of a suite of buttons like on the Forerunner 245, a digital dial and a separate button steer the Pace 2’s navigation. The robust battery life (20 days in standby mode, 30 hours of continuous GPS) outdoes that of our other top pick, the Garmin Forerunner 245, by days. Its speedy GPS acquisition time (about 13 seconds) launched us into our runs quickly, and its GPS distance and route-tracing precision were largely dependable (though not perfect). The lightest watch we’ve tested so far, the reasonably priced Pace 2 packs a raft of run-specific features to please a variety of runners. If you want a super-lightweight watch with a longer battery life than most-and you don’t care as much about extra smartwatch features-we think the Coros Pace 2 is your best option.
