Autonomy & GNSS: the nerve of war
Enduro 3 : 60 h in All Systems + Multi-Bande; 120 h in GPS alone; 9 p.m. in Max Battery; 320 h in GPS alone with solar (light conditions required). By shipment, we are talking about weeks. Suitable for a 200 km with margin or a 3–5 -day trek without recharge.
Ultra 3 : Up to 42 hours in daily use, 72 h in low consumption mode. In continuous GNSS follow -up, ~ 8 p.m. in optimized profile: a quick 100 km, a large mountaineering day. Fast load: 0–80 % ≈ 45 min.
Conclusion : If your criterion #1 is “do not recharge”, the advantage is clear for the enduro 3. If your criterion #1 is “versatility + native satellite safety”, ultra 3 checks the boxes.
GNSS & stability of the route (trail, forest, urban)
The two watches manage the double frequency. In dense forest and urban canyons, Enduro 3 Keep a slight advantage over long durations thanks to the possible dense recording without sacrificing the battery. In urban/mixed, Ultra 3 Start quickly, smoothly and is more than enough for leisure training. In the high mountains, the comfortable autonomy of the enduro 3 authorizes GNSS adjustments rich over several days.

Training & reading: two philosophies
Garmin Enduro 3 : Training Readiness, Training Load, HRV, Sleep Score, Recovery. These scores contextualize your sensations and guide charge and intensity. Ideal for long -term endurance.
Apple Watch Ultra 3 : Solid base (FC zones, estimated VO₂max, triathlon/swimming, track detection), coaching via apps (Trainingpeaks, Athlytic, Gentler Streak, etc.). No native reading, but very fluid workflows with iPhone.

Screen, ergonomics, robustness
Ultra 3 : Very bright OLED (~ 3000 nits), fluid entertainment, perfect readability indoors and end of the day. Crown + Action button + Tactile.
Enduro 3 : Unbeatable transflective half in full sun, very frugal. Reliable physical pimples in rain/gloves, tactile for the carto.
Robustness : titanium/sapphire glass, 100 m of sealing, siren (Apple), LED flash (Garmin).
Usage scenarios (final choice)
- Ultra-trail 100–200 km / trek 3–5 days :: Enduro 3 (cards + dense GNSS without recharge).
- Large bike passes + family safety in white zone :: Ultra 3 (integrated satellite).
- Triathlon / Swimming / track : the two are suitable; Ultra 3 shines by the iPhone apps and simplicity, Enduro 3 by the Pro Ant+/BT sensors and endurance.
- Daily use + regular sport + payments :: Ultra 3.
- Training Data-Driven + Chronic Load :: Enduro 3.
