For a dive-oriented rugged option, TechRadar reviews the Amazfit T-Rex 3 Pro; for multisport and swim training, consider Garmin Fenix 8 or Forerunner 970. No ATM or meter marking alone makes a watch a dive computer or proves it is safe at that real-world depth.
“Best waterproof smartwatch” is a common search phrase, but Apple’s guidance is more precise: its watches are water resistant, not waterproof. Choose based on the manufacturer’s allowed activities, swim features, phone compatibility, comfort, and any actual dive mode and limit.
Quick comparison
| Watch | Best fit | Resistance or dive information in the research | Key trade-off |
|---|---|---|---|
| Apple Watch Ultra 3 | iPhone users seeking swimming and supported recreational scuba | Wareable reports 100 m resistance and EN13319 recreational scuba compliance to 40 m. Apple says Ultra and later are limited to recreational scuba at 40 m. | Wareable says its 49 mm case can feel chunky; specialist dive metrics with Oceanic+ may require a subscription. |
| Apple Watch Series 11 | iPhone users who mainly swim | Apple rates Series 2 and later at 50 m under ISO 22810:2010 and permits shallow-water swimming; it does not recommend diving or high-velocity water sports. | Not a scuba watch or the ruggedest water-sports choice. |
| Samsung Galaxy Watch 8 | Android users seeking pool and open-water swimming | Wareable reports 5 ATM / 50 m and pool and open-water swimming support. | Do not confuse it with the Galaxy Watch Ultra models; verify current Samsung guidance. |
| Samsung Galaxy Watch Ultra / Ultra 2 | Android users considering a rugged watch for ocean use | Samsung’s cited support page covers Galaxy Watch Ultra: 10 ATM and IP68, ocean use, but not scuba diving. Verify the Ultra 2 manual separately. | Do not transfer one generation’s water guidance to another. |
| Amazfit T-Rex 3 Pro | Rugged value and dive-oriented features | TechRadar reports 10 ATM, dive certification to 45 m, and a dedicated dive-computer mode. | TechRadar notes Zepp OS lacks several major third-party apps. Its $399 review-time price is not a current offer. |
| Garmin Fenix 8 | Multisport and swim training | TechRadar lists 10 ATM, dive and multisport modes; battery figures vary by model variant. | Confirm the exact variant and current firmware before relying on detailed specifications. |
| Garmin Forerunner 970 | Swimming and triathlon training | Wareable lists it as a swim and triathlon choice; the supplied excerpts do not establish all resistance limits. | Check official documentation for the exact model’s allowed water activities. |
| Suunto Ocean | Diving and multisport | Wareable selects it for diving and multisport; the supplied research does not establish detailed resistance limits. | Check official product documentation and dive limits before purchase. |
Choose by water activity
| Activity | What to confirm | Starting point |
|---|---|---|
| Pool swimming | The manufacturer permits swimming and the watch has the swim features you need. | Apple Watch Series 11 for iPhone; Galaxy Watch 8 for Android, per Wareable’s guide. |
| Open-water swimming | An explicit open-water profile, GPS support, and current manufacturer guidance. | Wareable lists Apple Watch Ultra 3 and Galaxy Watch 8 for water use and swimming; check each current model’s documentation and software. |
| Ocean use | Model-specific permission, saltwater care, and a secure fit. | Samsung’s cited guidance permits ocean use for Galaxy Watch Ultra, but not scuba; verify separate guidance for Ultra 2. |
| Scuba diving | Explicit dive support and depth limits; distinguish a dive-capable smartwatch from a dedicated dive computer. | Apple Watch Ultra 3 is limited to supported recreational use up to 40 m. TechRadar reports dive features for Amazfit T-Rex 3 Pro and Garmin Fenix 8; confirm current manuals before use. |
| High-velocity water sports | Specific manufacturer approval; a resistance number alone is not enough. | Apple does not recommend Series 2 and later for water skiing or other high-velocity water sports. |
What water-resistance ratings mean
ATM, meter, and IP markings describe different tests. A nominal depth is a pressure rating under specified conditions, not a promise that you can take the watch to that depth. The 2026 WatchRanker explainer describes 5 ATM / 50 m as a defined resistance test commonly associated with swimming or surface immersion where the maker permits it, not scuba to 50 m. A 10 ATM / 100 m rating indicates greater pressure resistance, not dive-computer capability.
| Marking | What it indicates | What it does not establish |
|---|---|---|
| 3 ATM | Pressure equivalent to approximately 30 m under relevant test conditions, according to the WatchRanker explainer. | That the watch is suitable for swimming. |
| 5 ATM / 50 m | A defined watch-resistance test; commonly associated with swimming or surface immersion where the maker permits it. | Safe scuba use to 50 m. |
| 10 ATM / 100 m | Greater pressure resistance than 5 ATM. | That the watch is a dive computer or suitable for every dive. |
| IP68 | Dust and immersion ingress protection under specified IEC 60529 conditions. | The same pressure test as an ATM rating or permission to swim. |
| IP69K | Resistance to powerful, high-temperature water jets under a specified test. | Scuba suitability. |
Apple states: “Your Apple Watch is water resistant, but not waterproof.” Its guidance says Ultra and later can be used for recreational scuba diving up to 130 feet (40 meters). Series 2 and later are rated 50 m under ISO 22810:2010 for shallow-water swimming, not diving or high-velocity water sports. Follow the guidance for the exact model rather than generalizing across a brand.

Model notes
Apple Watch Ultra 3
Wareable names the Ultra 3 its best water-resistant smartwatch overall and reports 100 m resistance, EN13319 recreational scuba compliance to 40 m, swimming metrics, and compatibility with Oceanic+ for specialist dive metrics. Apple’s support guidance also sets the Ultra family’s recreational scuba limit at 40 m. It is a premium iPhone option, but Wareable notes that the 49 mm case may feel chunky. Check the app’s current compatibility, features, subscription terms, and regional availability before relying on it for diving.
Apple Watch Series 11
Wareable lists Series 11 as an iPhone-oriented swimming option. Apple’s guidance covers Series 2 and later: 50 m under ISO 22810:2010 and shallow-water swimming, but not scuba diving, water skiing, or other high-velocity water activities. It is the more appropriate choice for iPhone users whose needs are swimming rather than dive functions.
Samsung Galaxy Watch 8 and Ultra models
Wareable lists Galaxy Watch 8 as its Android swimming option, reporting 5 ATM / 50 m and pool and open-water swimming. Samsung’s cited U.S. support guidance is specifically for Galaxy Watch Ultra: it gives 10 ATM and IP68, permits ocean use, recommends rinsing with fresh water and drying afterward, and says it is not intended for scuba diving. Do not apply that guidance to Galaxy Watch Ultra 2 without checking its own current manual. TechRadar reports Galaxy Watch 9 at 5 ATM and IPX8; its review is not a substitute for Samsung’s model-specific water instructions.

FAQ
What is the best waterproof smartwatch?
“Waterproof” is common search wording, but it is not a promise of unlimited protection. Apple says its watches are water resistant, not waterproof. For 2026 water use, Wareable’s picks vary by need: Ultra 3 overall, Galaxy Watch 8 for Android swimming, and Series 11 for iPhone swimming.
Can I scuba dive to 50 m with a 5 ATM watch?
No. A 5 ATM / 50 m marking is a test rating, not a recommended scuba depth. Use a watch for diving only when its manufacturer explicitly supports the activity and provides applicable limits.
Is IP68 enough for swimming?
Not by itself. IP68 describes ingress protection under specified conditions and is not the same test as an ATM rating. Check the manufacturer’s permitted activities for the exact model.
Rank #4
Can I scuba dive with a Samsung Galaxy Watch Ultra?
Samsung’s cited U.S. support page says Galaxy Watch Ultra is not intended for scuba diving, despite its 10 ATM and IP68 ratings. Check the exact model’s current manual, especially for Ultra 2, rather than assuming the generations share the same guidance.
Can I scuba dive with an Apple Watch Ultra 3?
Apple says Ultra and later support recreational scuba up to 40 m. Follow Apple’s instructions and the limits of any compatible dive software; this does not make the watch suitable for unlimited or technical diving.
Does a 10 ATM rating mean a watch is a dive computer?
No. It indicates a higher pressure-resistance rating, not the functions or approved use of a dive computer. Confirm that the exact model has explicit manufacturer-supported dive modes and limits.
Which smartwatch is best for swimming on Android?
Wareable lists Galaxy Watch 8 as its best water-resistant Android smartwatch and reports pool and open-water swimming support. Check current model-specific instructions and software before relying on those features.
What should I do after swimming in the ocean?
Follow the model’s care instructions. Samsung’s cited guidance for Galaxy Watch Ultra recommends rinsing with fresh water and drying thoroughly after ocean use.
