Galaxy Watch8: two world exclusives available at the best price!
With its new range of connected watches unveiled in July 2025, Samsung is taking an unprecedented step forward in wrist-based health monitoring. The Antioxidant Index and Vascular Load mark the arrival of functionalities previously reserved for professional medical equipment.
Connected watches no longer just count your steps. The Wearables market is experiencing strong growth, driven by growing demand for increasingly sophisticated health monitoring. In this context, Samsung stands out with two major innovations: the Antioxidant Index and the Vascular Load. So when a promotional offer (up to an additional 15% off with the code WATCH8GO) allows you to discover these innovations at a reduced price, the opportunity is worth the detour.
The Antioxidant Index: a world first on a connected watch
The Galaxy Watch8 series arrives with the Antioxidant Index, a first on a connected watch. This index measures carotenoid levels in just 5 seconds. Concretely, it tells you if you are eating enough fruits and vegetables.
A low score? This is a sign that you need to review your plates. A good level? You are on the right track. Carotenoids are natural pigments present in fruits and vegetables, responsible for their yellow, orange or red color. These substances have an important antioxidant role, protecting the body against certain diseases such as cancer, diabetes or cardiovascular diseases.
Measuring their concentration in the body allows you to evaluate the quality of your diet and adjust your nutritional habits. Until now, this type of measurement required laboratory blood tests. Samsung democratizes access to this data thanks to advanced optical sensors integrated into the watch case.
Measure vascular load to monitor your heart every day
Second major innovation: Vascular Charge which allows precise monitoring of vascular and cardiac health. This function analyzes the impact of the user’s lifestyle on their cardiovascular system, complementing already available measurements such as ECG, blood pressure or oxygen saturation (SpO₂). A preventative approach that allows weak signals to be detected before they become problematic. Combined with other health sensors the Watch8it transforms the watch into a real portable laboratory.
A complete health ecosystem driven by AI
Samsung focuses on health with AI-powered features and deep integration of Galaxy AI and Gemini. Beyond the measures, it is the personalized support that makes the difference. The Sleep Coach analyzes your nights for a minimum of three days to establish a detailed score and offer you recommendations on your ideal bedtime. The watch can also alert you to the presence of sleep apnea via a two-night test.
On the sports side, the Running Coach assesses fitness level on a scale of 1 to 10 and designs a tailor-made training session, while continuing to share advice in real time. A 12-minute test is enough to determine your profile and receive personalized training plans.
Exynos chip: 5 hearts to watch over yours
All watches from the Galaxy Watch8 range integrate the Exynos W1000 chip (5 cores, 3 nm) and run under One UI 8 Watch. This architecture guarantees the fluidity necessary for real-time processing of health data, from the Running Coach to sleep analyzes including continuous cardiac measurements.
Samsung is renewing this chip already present on the previous generation, an assumed strategic choice. The Exynos W1000 remains one of the most powerful chips on the connected watch market, capable of managing multiple sensors simultaneously without slowing down. Its 3nm engraving also optimizes energy consumption, a crucial asset for maintaining autonomy despite the addition of new health functions such as the Antioxidant Index.
Are you considering taking the plunge? Take advantage of the offer additional 15% reduction on the Watch8 and Watch8 Classic, and -10% on the Watch Ultra 2025 with the promo code WATCH8GO, which can be combined with current Black Friday promotions (including the €50 trade-in bonus available on the Watch8 Classic and Watch Ultra)!
