The Galaxy Watch Ultra features several upgrades, including a faster Exynos processor, doubled storage, tripled LEDs in the bottom health sensors, and dual-band GPS. It also boasts a durable titanium design, a programmable Quick button, and a dynamic lug system for easy band swapping. Additionally, the watch offers improved heart rate accuracy and advanced fitness tracking capabilities.

The Galaxy Watch Ultra's dual-band GPS performs well in tests, showing improvements over previous Galaxy Watch models. It demonstrated better accuracy and consistency in maintaining the running path during a 5K run and a five-mile run. The GPS map results were also better than the Galaxy Watch 6 in previous tests. However, it's worth noting that some minor inconsistencies were observed during a track run, but overall, the dual-band GPS is a significant upgrade for the Galaxy Watch Ultra.

The Galaxy Watch Ultra and Garmin Forerunner 965 both offer accurate heart rate tracking, but the Ultra's dual-band GPS map performed better in tests2. While Samsung's heart rate results were generally close to the Garmin's, it lagged slightly during rapid changes. Overall, both watches provide similar HR accuracy, with the Ultra having a slight edge in GPS performance.
