Galaxy Watch Ultra 2 Leak Reveals Non-Invasive Glucose Monitoring and 4,000-Nit Display

The full specification sheet for Samsung's upcoming Galaxy Watch Ultra 2 has leaked, and the headline feature is non-invasive glucose trend monitoring — a capability that would make it the first mainstream smartwatch to offer blood sugar insights without a needle or patch.

Leaked Specifications

• Glucose monitoring: Non-invasive glucose trend tracking via Advanced BioActive Sensors — exclusive to the Ultra 2 model
• Display: 4,000-nit peak brightness (up from 3,000 nits on current Ultra)
• Processor: Dual-chip architecture — Snapdragon Wear Elite for performance + low-power co-processor for always-on health tracking
• Connectivity: 5G network support (confirmed for US; Europe may be limited to 4G)
• Health: Blood pressure monitoring, ECG, BIA body composition, skin temperature, advanced sleep tracking
• AI: Galaxy AI-powered health insights and predictive wellness alerts

Pricing and Timeline

The Galaxy Watch Ultra 2 is expected to launch at Samsung Unpacked in July 2026 alongside the Galaxy Z Fold 8, priced between $649 and $699. It will ship under the codename "Galaxy Watch 9 Ultra" internally.

What This Means for Buyers

Non-invasive glucose monitoring would be a genuine breakthrough — Apple has been working on this for years but hasn't shipped it. If Samsung delivers reliable readings, the Ultra 2 could become the top health-focused smartwatch regardless of ecosystem. Current Galaxy Watch Ultra owners at $639 may want to wait for the July reveal. Apple Watch Ultra 3 owners should stay put — currently $609 on Amazon. Compare options in our smartwatch guide.
