Wins overall by 1.1 points
Quick Verdict
The Garmin Venu 4 (41mm) takes this by a clear 1.1 points. Ten days, an FDA-cleared ECG and full iPhone/Android parity — with a $6.99/mo AI paywall. The Apple Watch SE 3 (40mm, GPS, Aluminum) only makes sense if it wins on a category you care about more than the total.
The Garmin Venu 4 (41mm) and Apple Watch SE 3 (40mm, GPS, Aluminum) are both current-generation smartwatch models, and the Apple Watch SE 3 (40mm, GPS, Aluminum) is $301 cheaper than the Garmin Venu 4 (41mm) ($249 vs $549.99). On Ecosystem Freedom, the Garmin Venu 4 (41mm) leads (8.5 vs 1.0/10) — the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing. On Battery Life, the Garmin Venu 4 (41mm) leads (9.0 vs 4.5/10) — real endurance between charges, judged against what the claim actually assumes rather than the headline number. On App Ecosystem, the Apple Watch SE 3 (40mm, GPS, Aluminum) leads (10.0 vs 6.0/10) — whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. Overall, the Garmin Venu 4 (41mm) scores 8.1/10 across our 8 scoring categories versus 7.0/10 for the Apple Watch SE 3 (40mm, GPS, Aluminum). Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Garmin Venu 4 (41mm) | Apple Watch SE 3 (40mm, GPS, Aluminum) |
|---|---|---|
| Price | $549.99 | $249.00 |
| Release Year | 2025 | 2025 |
| Phone Compatibility | Both iOS and Android, with no feature gated to a Garmin-branded phone (Garmin makes none). Garmin Connect is the same app on both platforms — the widest genuine compatibility of any premium watch here. | iPhone only. Requires iPhone 11 or later running iOS 26 or later. No Android support of any kind. |
| Claimed Battery Life (hrs) | 240✓ | 18 |
| What the Battery Claim Assumes | Garmin's 10-day 41mm figure is smartwatch mode with the always-on display OFF (the 45mm is rated 12 days). Enabling the always-on display, multi-band GNSS or continuous pulse-ox roughly halves it; Garmin publishes a separate 'battery life assumptions' support page per size because the modes differ so much. | Apple's 18 h figure assumes the same mixed-use day as Series 11 (90 time checks, 90 notifications, 15 min app use, 60 min workout) with the always-on display active and no LTE. Add overnight sleep tracking and you are charging twice a day. |
| Case Size (mm) | 41 | 40 |
| Display | 1.2-inch AMOLED with an optional always-on mode. Peak brightness is not published by Garmin. | LTPO OLED, always-on (new to the SE line), up to 1000 nits |
| Operating System | Garmin proprietary OS | watchOS 26 |
| Third-Party Apps | Garmin Connect IQ store — a real third-party store with watch faces, data fields and apps, but a much smaller and more fitness-skewed catalogue than the Play Store or App Store | Full on-device App Store — identical native watchOS catalogue to Series 11 and Ultra 3 |
| Health Features Enabled in the US | ECG app with AFib detection is FDA-cleared and available in the US (adults 22+ only, and region-restricted elsewhere). Also Pulse Ox, wrist temperature, HRV status, respiration and the new Health Status baseline alerts. No blood pressure and no hypertension notification. | Live in the US: ECG, irregular rhythm notifications, sleep apnea notifications and hypertension notifications (FDA-cleared), plus wrist temperature. Blood Oxygen uses the same post-Masimo design as Series 11 — captured on the watch, calculated on the iPhone. There is no depth gauge and no skin-temperature-driven ovulation estimate beyond what Series 11 offers. |
| Subscription Wall | Core metrics are free, but Garmin now runs a paywall: Garmin Connect+ costs $6.99/mo and gates Active Intelligence AI insights, extra coaching and premium performance dashboards. Buying a $549.99 watch does not include it. | None required; Apple Fitness+ ($9.99/mo) is optional. |
| LTE Option | The Venu 4 has no LTE variant; Garmin's cellular models sit in other product lines. | Separate SKU: Apple lists SE 3 GPS + Cellular at a $50 upcharge and it needs its own carrier line. The cellular 40mm has repeatedly been discounted to $249.99 at Amazon, closing the gap. |
| Water & Dust Rating | 5 ATM (50 m) | 50 m water resistant (WR50), IP6X dust resistant |
| Battery Replacement | Garmin does not sell a user or dealer battery-replacement service for the Venu line; out-of-warranty support is a discounted replacement unit. | Apple out-of-warranty battery service is a flat $99 — over a third of the watch's price. |
| Warranty | 12 months | 12 months |
| Colors | Slate with Black band, Silver with Periwinkle band, Lunar Gold with Bone band | Midnight, Starlight |
