Two watches to go out of the beaten track. One speaks the language of iOS, the other that of Android. Same promise: hold the shock, guide, measure, reassure. This comparison “Apple Watch Ultra Samsung Galaxy Watch Ultra” goes to the essentials: material, real uses, autonomy, ecosystems, prices.
Design and robustness
Apple Watch Ultra 2
49 mm grade 5 titanium housing, flat sapphire glass, apparent screws, Button actionintegrated mermaid. WR100 (ISO 22810) sealing and compliance in 133319 for leisure diving up to 40 m. IP6X dust resistance and MIL -STD -810H tests. A watch designed for cold, warm, sandy, salty environments.
Samsung Galaxy Watch Ultra
47 mm titanium case (1.5 “), sapphire glass, Quick Buttonprotected crown. 10 ATM + IP68 and MIL – STD – 810H. Screen very readable in the sun (up to 3,000 nits) and emergency mermaid up to 86 dB.
What it changes on the wrist – The Apple is wider and angular, very stable with gloves or underwater. The Samsung is a little more compact, less massive, comfortable for mixed city/land use. The two screens are extremely bright: clear readability in full sun as at night.
Health and safety sensors
Apple Watch Ultra 2
ECG, SPO₂, temperature (skin/water), always active altimeter, deep meter, detection of falls and accidents, sleep monitoring with detection of probable apneas. Leisure diving (up to 40 m) is based on dedicated apps (eg Oceanic+) with diving journal and surface GPS points.
Samsung Galaxy Watch Ultra
Bioactive sensor (ECG, cardiac frequency), followed by blood pressure via Samsung Health Monitor (calibration with brassard), metabolic aged index, detection of falls and SOS. Note: in Europe, ECG and tension require a compatible Galaxy smartphone for the dedicated app.
In practice – Beginners/confirmed divers: Apple advantage thanks to compliance in 13319 and the deep meter designed for regular aquatic use. Cardio + tension follow -up: Samsung advantage, provided you are in the Galaxy ecosystem.
Sport, GNSS and navigation
GPS double – frequency (L1 + L5) on both. In dense town or in conceded valleys, the precision progresses significantly compared to previous generations.
Apple side use
Precision Start, advanced racing/trail profiles, racing dynamics, cards and points of interest, backtrack, fine compass, mermaid and context button. Global logic favors the moving clarity and the reliability of alerts.
Samsung side use
Multisports mode (triathlon), GPX guidance with track back, personalized FC zones, Quick Button for fast transitions, Night Automatic Mode. The approach emphasizes the continuity of effort and the reading of the traces.
Autonomy: useful figures, no hollow promises
Apple Watch Ultra 2
- Up to 36 h in daily use of connected watch; up to 72 hours in energy reduction mode.
- In sport: approximately 12 hours (full GPS), 17 h (GPS in energy reduction) and up to 35 hours with spaced GPS/FC surveys.
Samsung Galaxy Watch Ultra
- Up to 100 h in energy saving mode; Up to 48 hours in sport -oriented energy saving.
- On a daily basis, most uses run between 36 and 48 hours according to AOD, LTE and GPS. Typical continuous GPS recording: about 6 p.m.
User translation – Bivouac weekend with GPX traces and offline photos: Samsung best takes long continuous recording. Apple compensates by fine energy saving settings and a very rich outdoor apps ecosystem. On a daily basis (work + long session), the two go: plan a recharge every 36 to 48 hours to keep margin.
Connectivity and ecosystems
Apple
LTE/UMTS ESIM, Bluetooth 5.3, Wi-fi, UWB of 2e Generation (Locate/Precision Find), Apple Pay, Gymkit. Works only with the iPhone: Siri, Plans, Health, Fitness+, Homekit are fitted without friction. The whole is consistent, responsive and secure.
Samsung
LTE ESIM, Bluetooth 5.3, Wi -Fi, NFC (Samsung Wallet), Wear OS with One Ui Watch, Smartthings integration and Galaxy AI functions (Energy Score, Coaching). Android 11 and more compatible, optimal experience with a galaxy smartphone. Large flexibility on the notifications, widgets and dials.
Materials, water resistance and details that matter
- Materials : titanium + sapphire on both; Grade 5 titanium for Apple. Specific bracelets for the sea, the mountain or the race on each side.
- Water resistance : Apple WR100 + EN13319 (Leisure diving 40 m); Samsung 10 ATM + IP68 (sea, swimming pool, water sports, no diving with dedicated instruments).
- Sensors : Apple (ECG, SPO₂, temperature, deepimeter); Samsung (ECG, Voltage, Ages, FC). SAMSUNG ECG/Voltage: require a Galaxy smartphone compatible in Europe.
- Sport features : Bi -fequence GPS on both, GPX/Track back and nervous multisports at Samsung; Precision Start, backtrack and structured diving at Apple.
Prize in France (September 2025)
- Apple Watch Ultra 2 : 899 € Public price (excluding titanium bracelets, certain packs at € 999). Promotions exist depending on the period.
- Samsung Galaxy Watch Ultra : € 699 at launch, often lower during ODR or bundles.
Which profile for which connected watch?
- IPhone on a daily basis, regular sea outingsneed a certified deep and a clear navigation: Apple Watch Ultra 2.
- Android (ideally Galaxy), triathlons, long GPX tracessiren and Quick Button thought of “terrain”: Samsung Galaxy Watch Ultra.
Purchasing experience
Clear summary
- Matter : titanium + sapphire on both; Apple in grade 5.
- Tightness : Apple WR100 + EN13319 (diving 40 m); Samsung 10 ATM + IP68.
- Health sensors : Apple (ECG, SPO₂, temperature, deepimeter); Samsung (ECG, tension, ages). SAMSUNG ECG/Voltage: Galaxy smartphone required in Europe.
- Sport/GNSS : Bi -Frequency L1+L5 on both; GPX/Track Back + Multisports at Samsung; Precision Start, backtrack and structured diving at Apple.
- Autonomy : Apple 36–72 h (12/17/35 h in GPS according to mode); Samsung 36–48 H typical, 100 h in economy, ≈18 h of continuous GPS.
- Connectivity : ESIM LTE, Bluetooth 5.3, Wi-fi on both; Apple adds the UWB and a deep stowage to iOS.
- Indicative price FR : Apple € 899; Samsung € 699 at launch (frequent promotions).
Sober conclusion: two philosophies, the same playground. If your digital life is centered on the iPhone and the sea is part of your outings, the Apple Watch Ultra 2 remains the most consistent. If you are living on Android, look for GPS endurance and the flexibility of an action button designed for multi -stage racing, the Galaxy Watch Ultra is essential. In both cases, we talk about tools: they must disappear at your service, not the opposite. Choose according to your journeys, not the technical sheet.
