The Samsung Galaxy Watch Ultra2 smartwatch will be equipped with an exclusive diving app, a product of collaboration with renowned diving brand Mares. However, unlocking its full potential requires an additional subscription. This smartwatch has successfully earned the EN13319 diving equipment certification, demonstrating its capability to support underwater activities at depths of up to 40 meters. It also boasts an impressive peak screen brightness of 5000 nits, ensuring visibility even in challenging lighting conditions.

Through the "Depth" app, users can conveniently access real-time data such as water depth, temperature, and dive duration. It's worth noting that, straight out of the factory, the watch does not include no-decompression limit tracking. To harness the complete functionality of a dive computer, users will need to download the dedicated companion app, which is slated for release.

The diving app presents three distinct subscription models to cater to divers of varying needs and expertise. The first is a complimentary timer mode, offering essential dive data and ascent rate alerts. For those seeking more, a standard paid snorkeling mode is available at $2.99 per month, adding GPS tracking and mapping capabilities. At the top tier, a premium paid diving mode is offered at $7.99 per month or $59.99 annually, supporting advanced professional features such as multi-gas diving and decompression calculations.

Safety remains paramount, and users are reminded to always have backup equipment on hand and adhere to established safety procedures when diving.
