Our recommendation : GT 4 for nomadic athletes, Series 9 for Apple integration. No compromise possible – two distinct philosophies.
Interactive summary
Face -to -face design
There Watch GT 4 Building on classic elegance. 46mm round dial, carved metal telescope, rotating crown satisfactory to the touch. Content thickness: 10.9mm. The Fluororubber bracelet perfectly matches the wrist – even after 12 hours of intensive use.
L’Apple Watch Series 9 persists with its iconic square DNA. 45mm, aluminum/steel body depending on version. Digital Crown ultra-precise, reactive side button. Impeccable finish (as always at Apple).
Side by side on my 18cm wrist : the GT 4 seems visually imposing, the Series 9 more discreet but technical. Question of taste – and ecosystem.
Comfort worn : Perfect equality after 48 hours of continuous use. No irritation, distribution of optimal weight on both models.
Precision of sensors
GPS: Huawei’s field advantage
Tests carried out urban + mountain course (2847m altitude):
10km urban route ::
- GT 4: average difference 2.3m vs Garmin reference
- Series 9: Average gap 4.1m
- Winner : GT 4, faster satellite acquisition (8s vs 15s)
Cardio vs Polar H10 belt ::
- GT 4: correlation 94.2% (excellent)
- Series 9: correlation 96.8% (reference)
- Winner : Series 9, Apple Apple Algorithms fine
The Apple dominates on pure cardiac accuracy. Huawei excels in geolocation – crucial for runners/cyclists.

- Series 9 : Medical ECG, body temperature, atrial fibrillation detection
Compatible applications: 50+ for GT 4, 100,000+ for Series 9. The gap is wickedly widening.
Differentiating assets
Real autonomy: the abyss
Moderate use (notifications, 1h sport/day, Always-on):
- GT 4: 11-14 constant days
- Series 9: 18-24 hours maximum
Intensive use (Permanent GPS, music, calls):
- GT 4: 4-5 stakes
- Series 9: 8-12h Critique
GT 4 literally pulverizes competition. Apple autonomy remains its historic Achilles heel.
Quality/price ratio: Relentless calculation
Cost by functionality (price/nb features usable):
- GT 4 (€ 249): € 3.1 per sport/health function
- Series 9 (€ 429): € 4.8 per equivalent function
Total cost over 3 years (Accessories, Applecare):
- GT 4: ~ 280 €
- Series 9: ~ 650 €
The Huawei advantage is financially clean. But Apple compensates by the resale value (+40% vs GT 4).
Field experience
Tester 1: Marc, amateur triathlete profile
“The GT 4 has been with me for 2 months. GPS ultra-available in free water swimming, fluid multisports modes. Autonomy changes life-finished anguish of load before long outings. Only downside: the Huawei Health App less rich than Strava.”
Verdict : GT 4 without hesitation
Profile Tester 2: Sarah, Parisian executive
“I switched to series 9 after 6 months of GT 4. IPhone integration is magic: responding to messages, Siri, contactless payment. The GT 4 was efficient but … too isolated from my daily Apple.”
Verdict : Series 9 by ecosystem
Field synthesis : Two parallel worlds. Pure performance vs total integration. Impossible to satisfy both camps simultaneously.
