Garmin Venu 4 (41mm) vs Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium)
Garmin Venu 4 (41mm)
Ten days, an FDA-cleared ECG and full iPhone/Android parity — with a $6.99/mo AI paywall.
Wins overall by 0.1 points
Quick Verdict
This is close. The Garmin Venu 4 (41mm) edges ahead by 0.1 points, but that margin is inside the noise — the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is a defensible pick on its own terms. Satellite SOS, 42-hour battery and a depth gauge — Apple's only watch that lasts a weekend.
The Garmin Venu 4 (41mm) and Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) are both current-generation smartwatch models, and the Garmin Venu 4 (41mm) is $249 cheaper than the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) ($549.99 vs $799). 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 App Ecosystem, the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) 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. On Battery Life, the Garmin Venu 4 (41mm) leads (9.0 vs 7.5/10) — real endurance between charges, judged against what the claim actually assumes rather than the headline number. Overall, the Garmin Venu 4 (41mm) scores 8.1/10 across our 8 scoring categories versus 8.0/10 for the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium), though the gap is close enough that your specific use case should decide it. 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 Ultra 3 (49mm, GPS + Cellular, Titanium) |
|---|---|---|
| Price | $549.99 | $799.00 |
| 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 on iOS 26. Satellite features additionally require the watch to be out of cellular range, and are US/Canada-region dependent. |
| Claimed Battery Life (hrs) | 240✓ | 42 |
| 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 42 h figure assumes the always-on display active and a mixed-use day with one workout; 72 h is Low Power Mode with the always-on display disabled and some sensors throttled. Multi-hour GPS workouts and satellite use pull it down sharply. |
| Case Size (mm) | 41 | 49 |
| Display | 1.2-inch AMOLED with an optional always-on mode. Peak brightness is not published by Garmin. | LTPO3 wide-angle OLED, always-on, up to 3000 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 — the same native watchOS catalogue as Series 11, plus dive and outdoor apps that use the depth sensor |
| 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 (all FDA-cleared), plus wrist temperature and a depth gauge. Blood Oxygen is the post-Masimo redesign — sampled on the watch, computed on the iPhone. |
| 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. Satellite features are included with the hardware, not sold as a subscription. |
| LTE Option | The Venu 4 has no LTE variant; Garmin's cellular models sit in other product lines. | Not an option — 5G cellular is included in every Ultra 3 and is part of the $799 price. A carrier line is still required and billed separately. |
| Water & Dust Rating | 5 ATM (50 m) | 100 m water resistant (WR100), IP6X dust, EN13319 dive certified to 40 m |
| 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, the same as the aluminium models. |
| Warranty | 12 months | 12 months |
| Colors | Slate with Black band, Silver with Periwinkle band, Lunar Gold with Bone band | Natural Titanium, Black Titanium |
Category Scores
Battery Life
The Garmin Venu 4 (41mm) leads clearly here, 9.0 against 7.5 — a 1.5-point margin on real endurance between charges, judged against what the claim actually assumes rather than the headline number. If that is what you are buying for, the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) does not close the gap elsewhere.
Health Tracking
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 9.6 against 8.2 — a 1.4-point margin on depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Fitness & GPS
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is marginally ahead, 9.4 to 9.2. A gap this small rarely decides a purchase on its own, though it counts if workout tracking, GPS accuracy, sport modes and training analysis is your priority.
Ecosystem Freedom
The Garmin Venu 4 (41mm) leads clearly here, 8.5 against 1.0 — a 7.5-point margin on 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. If that is what you are buying for, the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) does not close the gap elsewhere.
App Ecosystem
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 10.0 against 6.0 — a 4.0-point margin on whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Display
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 9.8 against 8.4 — a 1.4-point margin on panel type, brightness, always-on behaviour and legibility in sunlight. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Build & Durability
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 9.6 against 8.4 — a 1.2-point margin on case and glass materials, water and dust ratings, and how well it survives daily wear. If that is what you are buying for, the Garmin Venu 4 (41mm) does not close the gap elsewhere.
Value
The Garmin Venu 4 (41mm) is marginally ahead, 7.0 to 6.8. A gap this small rarely decides a purchase on its own, though it counts if what you get for the money once LTE upcharges and subscriptions are counted in is your priority.
