Samsung Galaxy Watch Ultra 2 Gets EN13319 Diving Certification

Samsung Galaxy Watch Ultra 2 leaks reveal EN13319 diving certification, 800 mAh battery, and 5,000 nit display ahead of the July 22 Galaxy Unpacked event.

Samsung is updating its wearable lineup with the Galaxy Watch Ultra 2, a device that finally brings professional diving certification to the series. This change matters because previous Ultra models lacked the specific standards required for serious underwater use. The Galaxy Watch Ultra 2 introduces EN13319 diving certification, bringing Samsung's underwater capabilities in line with those previously available from competing brands. We can see how this shift addresses a clear gap in the current market.

Titanium build and 800 mAh battery accompany new diving standards

The Galaxy Watch Ultra 2 arrives alongside the standard Galaxy Watch 9 models. Both devices draw leaked promotional images ahead of the July 22 Galaxy Unpacked event. The Ultra 2 builds on the rugged design of its predecessor with a titanium body. This material choice keeps the device durable while allowing for a thinner profile.

Galaxy Watch Ultra 2 Specifications

Battery Capacity (40mm): 390 mAh
Battery Capacity (44mm): 445 mAh
Battery Capacity (Ultra 2): 800 mAh
Display Brightness: 5,000 nits
Water Resistance Certification: EN13319, IP69K

Specs for the Ultra 2 show a significant jump in battery capacity to 800 mAh. The display brightness increases to 5,000 nits for better outdoor visibility. The device also gains EN13319 certification for diving and IP69K water resistance. These ratings confirm the watch can handle high-pressure water environments.

The new design is 12% thinner than the original Ultra model. Standard Galaxy Watch 9 sizes also see battery updates. The 40mm version increases to 390 mAh and the 44mm version reaches 445 mAh. The increased battery capacities, ranging from 390 mAh to 800 mAh, indicate improved endurance for the Galaxy Watch 9 and Ultra 2 models.
