Galaxy Watch Ultra 2 Final Spec Update: 5,000-Nit Display, Bluetooth 6.0, and IP69K Rating Confirmed

Android Authority has published what appears to be the final, most complete spec sheet for the Galaxy Watch Ultra 2, revealing several details not previously confirmed — most notably a 5,000-nit peak brightness display that would make it the brightest smartwatch screen ever shipped.

New Details Confirmed

• Display brightness: 5,000 nits peak — a 67% increase from the original Galaxy Watch Ultra's 3,000 nits, and significantly brighter than the Apple Watch Ultra 3's 2,000 nits. This ensures full readability in direct sunlight during outdoor activities
• Bluetooth 6.0: Both the Watch 9 and Ultra 2 will be among the first smartwatches to ship with Bluetooth 6.0, bringing improved connection stability, lower latency, and better power efficiency
• IP69K rating: The Ultra 2 adds IP69K certification for high-temperature, high-pressure water resistance — a step above the standard IP68 and 5ATM ratings, offering protection against steam cleaning and pressurized water jets
• Dual-band Wi-Fi: Both 2.4GHz and 5GHz support for faster data transfers and more reliable connectivity

Full Spec Summary

Combined with previously leaked details, the Ultra 2 spec sheet now reads: Snapdragon Wear Elite (3nm), 800mAh battery, 5,000-nit 480×480 display, Bluetooth 6.0, 5G RedCap, IP69K, experimental AGEs/antioxidant/vascular load sensors, and up to 64GB storage. Price holds at $699 with pre-orders opening tomorrow at Unpacked.

What This Means for Buyers

The 5,000-nit display alone makes the Ultra 2 a compelling upgrade for outdoor enthusiasts who found the original Ultra's screen insufficient in bright sunlight. Combined with Bluetooth 6.0 and IP69K, Samsung is positioning this as the most rugged mainstream smartwatch available. The Apple Watch Ultra 3 at $640 offers a more mature health ecosystem but caps at 2,000 nits. If outdoor visibility matters, the Ultra 2 wins on paper. Compare both in our smartwatch guide.
