Galaxy Watch Ultra 2 Experimental Health Sensors Detailed: AGEs, Antioxidant Levels, and Vascular Load Tracking Coming at $699

Ahead of the July 22 Unpacked reveal, new details have emerged about the Galaxy Watch Ultra 2's most ambitious feature: three experimental health sensors that go far beyond standard heart rate and SpO2 tracking.

The Three Experimental Sensors

• AGEs (Advanced Glycation End-Products): Measures the accumulation of AGEs in your body through optical spectroscopy. High AGEs levels are associated with accelerated aging, diabetes, cardiovascular disease, and metabolic dysfunction — making this a potential early-warning system for long-term health risks
• Antioxidant Level Monitoring: Estimates your body's antioxidant capacity, which may reflect dietary quality, oxidative stress, and recovery status
• Vascular Load: Tracks arterial stiffness and blood vessel health, providing a window into cardiovascular fitness that standard heart rate monitoring cannot offer

How They Work

All three sensors operate separately from Samsung's existing BioActive sensor (which handles heart rate, ECG, blood pressure, and body composition). They require a one-time calibration during initial setup and take approximately 30 seconds per reading. Samsung labels these as "experimental" because they are not FDA-cleared and are intended for wellness insights rather than medical diagnosis.

Hardware Specs Recap

• Price: $699 — matching the original Galaxy Watch Ultra
• Battery: 800mAh (35% larger than the original)
• Display: 3,000-nit Super AMOLED, 480 × 480 px
• Chip: Snapdragon Wear Elite (3nm)
• Connectivity: 5G RedCap in US and South Korea, LTE elsewhere
• Availability: Pre-orders July 22, shipping August 5

What This Means for Buyers

The experimental sensors make the Ultra 2 the most sensor-dense smartwatch on the market — no other watch tracks AGEs or vascular load. However, "experimental" means limited clinical validation and no FDA clearance. If you want proven, medically actionable health data, the Apple Watch Ultra 3 at $640 offers FDA-cleared ECG and crash detection. If you want bleeding-edge health insights and don't mind the experimental label, the Ultra 2 at $699 is compelling. Compare both in our smartwatch guide.
