Side-by-Side Comparison
| Spec | Garmin Forerunner 970 (47mm, titanium bezel) | Polar Grit X2 (45mm) |
|---|---|---|
| Price | $749.99 | $799.99 |
| Release Year | 2025 | 2025 |
| Display | 1.4-in 454x454 AMOLED touchscreen with sapphire lens, optional always-on | 1.28-in 416x416 AMOLED with sapphire lens, optional always-on |
| Smartwatch Battery ( days) | 15✓ | 7 |
| Always-On Display Cost | 7 days with always-on display, and GPS drops from 26 h to 20 h / multiband from 21 h to 15 h. DC Rainmaker found default brightness burns battery 'at an astonishing speed' and recommends about one-third brightness. | Polar does not publish a separate always-on smartwatch figure in the sources reviewed; the headline 7 days is already the shortest smartwatch runtime in this comparison |
| Battery, Single-Band GPS ( h) | 26 | 90✓ |
| Battery, Multiband GPS ( h) | 21 (the5krunner spec sheet) / 19 (garminrumors spec wiki) — sources conflict | 30 |
| GNSS Bands | Multi-band L1+L5 (GPS, GLONASS, Galileo, BeiDou, QZSS) with SatIQ auto-selection | Dual-frequency GNSS (GPS, GLONASS, Galileo, BeiDou, QZSS). The 90 h figure is Eco training mode with reduced fixes; 30 h is the full Performance mode with GPS and wrist HR running. |
| Onboard Maps | Full TopoActive topographic maps preloaded, free, with on-device routing and turn-by-turn, plus 2,000+ ski resorts and 43,000 golf courses in 32 GB | Offline TOPO maps for North America and Europe preloaded, with contour and POI layers; other regions download free. No on-device rerouting, and the compass must be calibrated before navigation. |
| Music Storage | 32 GB, roughly 2,000 songs, offline Spotify / Amazon Music / Deezer plus sideloaded MP3 | None. The watch controls phone music only — there is no on-device storage and no streaming. |
| Training Platform & Subscription | Garmin Connect is free and every core training metric — Training Readiness, Training Load, Training Status, HRV Status, Body Battery, recovery time — is Firstbeat-derived and free on the watch (Garmin bought Firstbeat in 2020). Connect+ is $6.99/mo or $69.99/yr and adds only AI wellness prompts, 3D maps, Trails+ routing, extra badges and nutrition logging — nothing a training plan depends on. But Running Economy and Step Speed Loss — two of the 970's headline new metrics — do not work from the wrist at all: they require the separate HRM-600 chest strap, which DC Rainmaker calls an upsell. | Polar Flow app and web are genuinely free with no paid tier. Training Load Pro, Nightly Recharge, Sleep Plus Stages and FitSpark are Polar's own science, not Firstbeat-licensed. |
| External Sensor Support | ANT+ and Bluetooth; HRM-200/HRM-600 straps, Stryd, power meters, Varia radar | Bluetooth LE only — no ANT+, so ANT+-only power meters and older straps will not pair. A Polar H10 chest strap is the recommended fix for the wrist sensor. |
| Data Export | Full .FIT file access over USB/MTP plus free automatic sync to Strava, TrainingPeaks, Runalyze, intervals.icu and others through Garmin Connect. | Free .FIT/TCX/GPX export from Polar Flow plus automatic sync to Strava, TrainingPeaks and Komoot |
| Warranty | 12 months | 24 months |
| Colors | Carbon Gray DLC Titanium / Black, Titanium / Whitestone | Black |

GPS Accuracy
The Garmin Forerunner 970 (47mm, titanium bezel) leads clearly here, 9.0 against 8.0 — a 1.0-point margin on trace quality in cities and under tree cover — multiband L1+L5 hardware plus what independent testers measured in the real world.. If that is what you are buying for, the Polar Grit X2 (45mm) does not close the gap elsewhere.
Battery Honesty
The Polar Grit X2 (45mm) is marginally ahead, 6.0 to 5.8. A gap this small rarely decides a purchase on its own, though it counts if how much of the headline battery claim survives the mode you would actually train in: all-systems plus multiband, always-on display, music playing. The number on the box is almost always the slowest, least accurate mode. is your priority.
Training & Recovery
The Garmin Forerunner 970 (47mm, titanium bezel) leads clearly here, 9.4 against 8.2 — a 1.2-point margin on depth of load, readiness and recovery analysis, and how much of it is free rather than gated behind a subscription or an extra chest strap..

Heart Rate
The Garmin Forerunner 970 (47mm, titanium bezel) leads clearly here, 8.4 against 5.0 — a 3.4-point margin on optical wrist accuracy during intervals and burst efforts, and whether the watch pairs with ANT+ and/or Bluetooth chest straps as a fix..

Pros & Cons
Garmin Forerunner 970 (47mm, titanium bezel)
Pros
- +Real preloaded TopoActive maps with routing, not a breadcrumb — the reason to step up from the 570
- +Multi-band GNSS plus SatIQ gives one of the most reliable traces in the category
- +ECG, skin temperature, flashlight and a sapphire/titanium build in a 56 g case
- +Deepest free training stack of any watch here — Training Readiness, Load, HRV Status and Garmin Coach cost nothing
Cons
- −Multiband battery is 21 h at most, and 15 h with always-on: the display, not the GNSS chip, is what kills it
- −Running Economy and Step Speed Loss require the extra HRM-600 chest strap — the watch alone cannot produce them
- −Sources disagree on the multiband figure (21 h vs 19 h), which is exactly the spec most buyers compare on
- −$749.99 buys less GPS runtime than a $429 Coros Apex 4 gives in its most accurate mode
- −DC Rainmaker recorded open-water swim HR errors not typical of previous Garmins
Polar Grit X2 (45mm)
Pros
- +Preloaded free offline TOPO maps for North America and Europe, with sapphire and a steel bezel
- +Polar Flow is completely free — no subscription tier exists, unlike Garmin Connect+
- +62 g with strap and MIL-STD-810H tested, one of the most comfortable big outdoor watches here
- +ECG, SpO2 and skin temperature on top of Polar's well-regarded Nightly Recharge recovery model
Cons
- −DC Rainmaker's optical HR testing was damning: it 'missed every single interval' on 400 m repeats and recorded 3,100 m for a ~1,900 m open-water swim. Budget for an H10 chest strap.
- −7 days of smartwatch battery is the shortest in this comparison, and 30 h in full Performance mode is beaten by a $249 Coros
- −No music storage at all on a $799.99 watch
- −Bluetooth only — no ANT+ support
- −Navigation demands a compass calibration first, and turn-by-turn has to be switched on manually after picking a route
