Main trade-off
Garmin Forerunner 970
Running economy needs specific session types and an accessory such as HRM 600. Subscription music needs its service conditions.
Head-to-head
Choose 970 for compatible subscription downloads, the lighter 56 g package and a larger AMOLED display. Choose APEX 4 46 mm when its MIP display, local MP3 workflow and higher published recording ceilings suit long outings. APEX’s supplied band starts at 140 mm versus 135 mm for 970. The Garmin running economy estimate also needs qualifying outdoor sessions and compatible extra hardware. Both still need a connected phone for ordinary calls.
Before you choose
APEX 4’s dual-frequency ceiling is 41 hours versus 970’s 21-hour multiband figure. With local music, the published figures narrow to 15 and 12 hours. Those are different manufacturers’ conditions, not evidence of a measured runtime ratio. More importantly, APEX needs computer-transferred MP3 files while 970 supports compatible subscription downloads. Someone whose long runs depend on a Spotify library should first decide whether rebuilding a local-file music routine is acceptable. The larger no-music number does not answer that question. Use the simultaneous-feature figure and keep reserve once the library choice is settled.
What this is based on
Long outdoor events plus subscription music crossed with file compatibility and mode-specific battery ceilings. No matched runtime ratio or guaranteed finish.

Main trade-off
64 g with the selected silicone band, which starts at 140 mm. Incoming calls only, with the phone connected and COROS app running. No streaming-service music downloads.

Forerunner 970 vs APEX 4 46 mm for long routes, Spotify and a small wrist. Compare the actual music setup and the inputs behind advanced running data.
These are cross-shopped premium mapped sports watches with Sapphire lenses, music and paired-phone call interfaces. The buyer can choose a lighter AMOLED Garmin or a MIP COROS with higher stated recording ceilings. Music source, exact fit and training inputs make the decision non-trivial.
Winner by situation
APEX’s supplied band and MP3 workflow do not meet those exact constraints.
APEX has higher published recording ceilings, with reserve still required.
The Garmin metric requires different inputs. No equivalent COROS claim is made.
Both have a supported paired-phone call interface. Neither makes the phone unnecessary.

The 970’s supplied band covers 137 mm, while the selected APEX 4 46 mm band begins at 140 mm. The Garmin also weighs 56 g rather than 64 g and has a larger 1.4-inch display. That combination can matter for a buyer wanting map space without adding a separately researched strap. It does not prove better comfort or readability. APEX’s smaller case diameter does not remove the band boundary. Try the actual watch and layout, especially if overnight wear or limited dexterity makes small physical differences important.
Small wrist plus map-display preference crossed with selected band range, total weight and display. No medical, dexterity or comfort benefit inferred.
A call from family may arrive while you are crossing a road, handling a dog or unable to stop immediately. Once you are in a suitable place, returning it becomes the job. The 970 Phone app can call a contact or dial through a connected compatible phone. APEX can receive calls on the watch but cannot start one, so a callback needs the phone or another supported interface. Its receiving function also requires the COROS app running in the background. If you usually answer the first ring after stopping, APEX may be enough. If missed calls are common and the phone stays buried in a pack, 970 removes a more complete part of the routine.
Interrupted activity plus a packed phone crossed with incoming-only versus incoming-and-outgoing calling. No safety, reception or call-quality guarantee.

Meaningful differences
| What changes | Garmin Forerunner 970 | COROS APEX 4 46 mm | Why it matters |
|---|---|---|---|
| Exact display and fit | 1.4-inch AMOLED, 56 g, 135–205 mm band. | 1.3-inch MIP, 64 g, 140–215 mm band. | A small wrist can rule out the supplied APEX band before battery matters. |
| Music source | Compatible subscription downloads with plan and renewal conditions. | Computer-transferred MP3 files. | A streaming library and an owned file library lead to different choices. |
| Dual-frequency activity | Multiband up to 21 hours or 12 with music. | Dual frequency up to 41 hours or 15 with music. | The apparent no-music gap narrows sharply when local playback is added. |
| Returning a family call | Watch Phone app can dial or call a contact through the connected phone. | Receives calls but cannot start one from the watch. Phone and background COROS app required. | Missing the first ring creates a different task from answering it. |
What you give up
Recommendation switch
Choose Garmin Forerunner 970. 970 fits the existing routine with explicit service conditions.
Choose COROS APEX 4 46 mm. APEX’s published endurance can justify its physical trade-offs.
What matters in practice
You want a watch for long outdoor days without buying a music workflow or training metric that your ordinary week cannot support.
