Garmin Forerunner 965 vs Apple Watch Series 11: Worth $170 More?

The Garmin Forerunner 965 and Apple Watch Series 11 sit at similar price points but serve fundamentally different users. One is an athlete’s training computer that happens to tell time; the other is a premium smartwatch that happens to track workouts. Choosing between them comes down to what you value more: training depth or daily-life convenience.

Key Differences

• Battery life: The Forerunner 965 lasts up to 23 days in smartwatch mode and 31 hours with GPS. The Apple Watch Series 11 needs a charge every night, with roughly 8 hours of GPS runtime.
• GPS accuracy: Garmin uses multi-band GNSS for superior positioning in dense tree cover and urban canyons. Apple relies on single-band GPS.
• Smartwatch features: The Series 11 has a built-in mic and speaker for phone calls, Siri, and LTE connectivity. The Forerunner 965 has none of these.
• Display size: Apple’s 1.96-inch screen dwarfs Garmin’s 1.4-inch panel, making it easier to read maps and notifications at a glance.
• Training tools: Garmin offers structured workouts, training load analysis, recovery metrics, race predictor, and ANT+ sensor support — features the Apple Watch simply doesn’t match.
• Ecosystem lock-in: The Apple Watch requires an iPhone. The Forerunner 965 works with both iOS and Android.

Deep Dive Comparison

Design & Comfort

At 53g, the Forerunner 965 is light for a feature-packed GPS watch, thanks to its fiber-reinforced polymer case with titanium bezel. It wears like a dedicated sport watch — chunky by fashion standards but comfortable during long runs. The Apple Watch Series 11, at just 37.8g in its 46mm aluminum case, is noticeably lighter and sleeker on the wrist. It transitions from the gym to the office without looking out of place.

Both are water resistant — the Forerunner at 5 ATM and the Series 11 at 50 meters (functionally equivalent for swimming). The Apple Watch adds a depth gauge and water temperature sensor, giving it a slight edge for open-water swimmers.

Battery Life

This is where the Forerunner 965 dominates the conversation. With up to 23 days in smartwatch mode and 31 hours of continuous GPS, you can run an ultramarathon, forget to charge it for a week, and still have juice left. The Apple Watch Series 11 tops out at about 24 hours of general use and roughly 8 hours with GPS active — meaning marathon runners may need to worry about their watch dying before the finish line.

If you train daily and hate managing chargers, the Garmin is in a different league. Apple Watch users will need to build nightly charging into their routine.

Health & Fitness Features

Both watches cover the essentials: optical heart rate, blood oxygen monitoring, and a barometric altimeter. The Forerunner 965 adds Pulse Ox tracking, a thermometer for acclimatization data, and deep training metrics like VO2 max estimates, training status, recovery advisor, and race predictions. It also supports ANT+ connections for chest straps, power meters, and cycling sensors — critical for serious athletes.

The Apple Watch Series 11 counters with an electrical heart sensor for ECG readings, a skin temperature sensor for cycle tracking, and a depth gauge. Its health notification system — irregular heart rhythm alerts, fall detection, crash detection — is more polished for everyday safety monitoring. For clinical-style health alerts, Apple has the edge. For training performance analysis, Garmin wins handily.

GPS accuracy is another clear Garmin advantage. Multi-band GNSS on the Forerunner 965 provides more reliable tracking under tree cover, near tall buildings, and in mountainous terrain. The Series 11’s single-band GPS is fine for most road runs but can drift in challenging environments.

Smart Features

The Apple Watch Series 11 is a full smartwatch. It takes phone calls, plays music through a built-in speaker, supports Siri voice commands, handles Apple Pay, and offers LTE connectivity so you can leave your phone at home entirely. The app ecosystem is massive — from Spotify streaming to third-party workout apps.

The Forerunner 965 handles notifications, contactless payments via Garmin Pay, and stores up to 32GB of music for offline playback through Bluetooth headphones. But there’s no microphone, no speaker, and no cellular option. It’s a capable notification mirror, not a phone replacement.

Both support NFC payments. Both sync with their respective ecosystems (Garmin Connect vs. Apple Health). If staying connected away from your phone is important, the Apple Watch is the clear pick.

Price & Value

The Apple Watch Series 11 launches at $429, while the Garmin Forerunner 965 carries an MSRP of $599. On paper, the Apple Watch looks like the better deal — and it is, if you want a do-everything smartwatch. But for dedicated athletes, the Garmin’s multi-band GPS, three-week battery, and advanced training analytics justify the premium. You’re paying for tools that directly improve your training, not just convenience features.

Keep in mind that the Forerunner 965 launched in early 2023, so street prices may dip below MSRP. The Series 11, as a 2025 release, will hold its price for a while.

The Verdict

Buy the Garmin Forerunner 965 if you train seriously — whether that’s marathon prep, triathlon season, or structured interval work. Its multi-band GPS, 23-day battery, ANT+ sensor support, and deep performance analytics are built for athletes who track training load, not just calories. You’ll also appreciate it if you use Android or simply refuse to charge a watch every night.

Buy the Apple Watch Series 11 if you’re an iPhone user who wants one device for fitness, health monitoring, communication, and daily convenience. It’s lighter, has a bigger screen, takes phone calls, and costs $170 less. The fitness tracking is solid for most gym-goers, runners, and swimmers — just know you’ll be tethered to a charger nightly, and the GPS won’t match Garmin’s precision on technical trails.

For most people who work out regularly but aren’t training for competition, the Apple Watch Series 11 delivers more daily value for less money. But for dedicated endurance athletes, the Forerunner 965 remains the gold standard — and no amount of smartwatch polish can replace what it offers on race day.
