In terms of size, the Forerunner 965 measures 47.1 x 47.1 x 13.2 mm. This closely matches the Vantage V3’s dimensions of 47 x 50.8 x 14.5 mm. The similarity in size ensures that both watches maintain a substantial presence on the wrist without being overly bulky. Which means they suitable for both everyday wear and during workouts.

AMOLED display

AMOLED is where it is at. The two devices have been upgraded to this type of display from lower spec options of its predecessors.

The Forerunner 965 sports a slightly larger 1.4-inch diameter screen compared to the Vantage V3’s 1.39-inch. The display resolution is identical at 454 x 454 pixels, ensuring crisp and clear visuals. The always-on screen option on both devices means that key information is just a glance away. This is the case whether you’re in full sunlight or the dim light of dawn.

The Forerunner 965 is available in classic Black and a Whitestone/Powder Gray option. This provides a more traditional look that can easily transition from the track to the boardroom. The Vantage V3 offers a more vibrant palette with Sunrise Apricot, Night Black, and Sky Blue. Those colour options cater to those who prefer a pop of color and a more expressive style.

When it comes to water resistance, the Forerunner 965 is rated at 5 ATM. This suggests it can withstand pressures equivalent to a depth of 50 meters. The Vantage V3 is similarly rated at WR50, which generally means it’s suitable for swimming but not high-impact water sports or diving.

In terms of satellite connectivity, again not much of a difference. The Forerunner 965 and Vantage V3 feature dual-frequency GPS, GLONASS, and Galileo support, ensuring accurate tracking of outdoor activities. The Vantage V3 goes a step further by including BeiDou and QZSS, which could offer improved coverage and accuracy, particularly in challenging environments.

The Forerunner 965 boasts 32 GB of onboard storage. This is used not only for data but also for music storage. The Vantage V3 matches the Forerunner in terms of storage capacity but does not support onboard music storage, which means athletes will need to carry their smartphones if they want to listen to music during their activities. The V3 also lacks an NFC chip for contactless payments.

Battery life

Battery life is important for a sports watch. The Forerunner 965 certainly doesn’t disappoint on this count. With up to 23 days in smartwatch mode, it ensures that even the most active users won’t be left frequently searching for a charger. When it comes to GPS usage, the watch can last an excellent 31 hours in GPS-Only GNSS mode. For those who need the utmost precision there’s the All-Systems GNSS mode plus Multi-Band, which can go up to 19 hours. Even with music playing, which traditionally drains battery quickly, you can expect up to 10.5 hours of GPS-Only GNSS mode, ensuring your soundtrack to the grind won’t cut out mid-session.

The Polar Vantage V3, offers a shorter duration in smartwatch mode at up to 8 days. But it shines in GPS-connected training mode, where it can last up to a remarkable 61 hours with single-frequency GPS (power save) and optical heart rate. With dual-frequency GPS and optical heart rate this falls to a, still excellent, 47 hours. For ultra-endurance athletes, the Vantage V3’s power save training mode extends this even further to 140 hours, making it a powerhouse for those long, uninterrupted stretches of training or racing.
