Side-by-Side Comparison
| Spec | COROS APEX 4 (42mm) | Garmin Forerunner 970 (47mm, titanium bezel) |
|---|---|---|
| Price | $429.00 | $749.99 |
| Release Year | 2025 | 2025 |
| Display | 1.2-in 240x240 3rd-gen transflective MIP, always-on, no AMOLED battery penalty — but DC Rainmaker and Tom's Guide both call it dim indoors and in low light | 1.4-in 454x454 AMOLED touchscreen with sapphire lens, optional always-on |
| Smartwatch Battery ( days) | 15 | 15 |
| Always-On Display Cost | No always-on penalty — the MIP screen is permanently on. (The 46 mm version is rated 24 days smartwatch and 65 h all-systems GPS if you want the bigger numbers.) | 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. |
| Battery, Single-Band GPS ( h) | 41✓ | 26 |
| Battery, Multiband GPS ( h) | Not published by COROS for the 42 mm in any source reviewed here. For reference the 46 mm is rated 65 h all-systems vs 41 h dual-frequency — expect a similar ~35-40% drop. | 21 (the5krunner spec sheet) / 19 (garminrumors spec wiki) — sources conflict |
| GNSS Bands | Dual-frequency L1+L5 chipset covering GPS, GLONASS, Galileo, BeiDou and QZSS. DC Rainmaker warns GPS accuracy degrades noticeably when route navigation is running. | Multi-band L1+L5 (GPS, GLONASS, Galileo, BeiDou, QZSS) with SatIQ auto-selection |
| Onboard Maps | Free global offline topographic and landscape maps with street/trail names and POIs, downloaded through the COROS app, plus turn-by-turn on preloaded routes. No ClimbPro equivalent and no automatic rerouting. | 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 |
| Music Storage | MP3 files only, sideloaded. No streaming services and no phone-music control. | 32 GB, roughly 2,000 songs, offline Spotify / Amazon Music / Deezer plus sideloaded MP3 |
| Training Platform & Subscription | COROS app and EvoLab analytics are entirely free, no subscription tier. COROS' own metrics, not Firstbeat. | 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. |
| External Sensor Support | Bluetooth only — no ANT+ at all, which rules out ANT+-only power meters | ANT+ and Bluetooth; HRM-200/HRM-600 straps, Stryd, power meters, Varia radar |
| Data Export | Free .FIT/GPX export plus auto-sync to Strava, TrainingPeaks, Apple Health and Health Connect | Full .FIT file access over USB/MTP plus free automatic sync to Strava, TrainingPeaks, Runalyze, intervals.icu and others through Garmin Connect. |
| Warranty | 24 months | 12 months |
| Colors | Black | Carbon Gray DLC Titanium / Black, Titanium / Whitestone |

Pros & Cons
COROS APEX 4 (42mm)
Pros
- +Free global offline topo maps with street and trail names at $429 — Garmin charges $749.99 before you get maps
- +Titanium bezel and sapphire glass at a price where rivals use aluminium and Gorilla Glass
- +MIP means the 41 h all-systems figure is what you get, with no always-on display tax
- +Two years of warranty and zero subscriptions anywhere in the platform
Cons
- −COROS does not publish a dual-frequency battery figure for the 42 mm, and dual-frequency is where accuracy actually lives
- −DC Rainmaker measured a real GPS accuracy drop when a route is loaded and navigation is active
- −MIP display is dim indoors and at night compared with every AMOLED rival here
- −No ANT+, no NFC payments and no LED flashlight
- −The depth gauge has no certification and cannot record dives to the app, and there are no dive sport profiles
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
