Editor's take
Samsung's rugged Ultra2 is rated 100m water resistant, IP69K dust-tight and EN13319 dive-certified with a built-in Mares dive computer app, plus a 5,000-nit display for outdoor visibility — a genuine rival to Apple's Ultra 4 with 198 reviews at 4.6 stars already behind it.
The Ultra2 is built specifically for outdoor and water use: it's rated IP69K (dust-tight) and 10ATM, with Amazon's spec table confirming 100m water resistance and EN13319 dive certification. A built-in dive computer app from Mares gives real-time ascent/descent monitoring, depth limit notifications and safety stop information — features aimed squarely at divers rather than casual swimmers. The 1.9-inch display reaches up to 5,000 nits of brightness, well above typical smartwatch displays, for visibility in direct sunlight.
Trail running gets dedicated support too: path, elevation and pace guidance plus personalized hydration alerts. Built-in GPS, LTE cellular, NFC and Wi-Fi are all confirmed in Amazon's spec table, and the watch weighs 2.08 ounces (about 59g) on its own.
No battery-life figure was published in this listing's specs or bullets, so that's left unconfirmed rather than assumed. With 198 reviews at 4.6 stars, it has a solid, credible review base — and at $699 it undercuts the Apple Watch Ultra 4 by $80 while matching its 100m water resistance.
Pros
- Confirmed 100m water resistance, IP69K dust rating, and EN13319 dive certification with a built-in dive computer app
- 5,000-nit display brightness for outdoor visibility
- 198 reviews at 4.6 stars — a solid, credible review base
- Built-in GPS, LTE cellular, NFC and Wi-Fi all confirmed
Cons
- No battery-life figure published in this listing
- Android-only, requires a Samsung or other Android phone
- Dive computer app functionality depends on a third-party app (Mares), not native Samsung software
- At 47mm, it's a large watch that may not suit smaller wrists
Ideal for: Android users who dive, hike or trail run and want confirmed 100m water resistance and dive certification at a lower price than Apple's Ultra 4.
Reviews
198 reviews averaging 4.6 out of 5 — a solid, well-established rating.
