For the 2025 models, choose the Galaxy Watch8 Classic if you want its rotating bezel, stainless-steel case, and traditional watch styling. Choose the Galaxy Watch Ultra if you prioritize its titanium case, larger stated battery capacity, or higher published water-resistance rating. These are specification-based recommendations, not hands-on test results.
This comparison covers the Galaxy Watch8 Classic and Galaxy Watch Ultra (2025), not Samsung’s newest listed generations. Samsung’s US comparison page also lists the Watch9 and Ultra2, so buyers considering the current lineup may want to compare those models as well.

Battery life: compare the claims carefully
Samsung lists typical battery capacities of 445mAh for the Watch8 Classic and 590mAh for the Ultra. Its comparison gives the Ultra a claim of up to 60 hours with always-on display enabled. Samsung says its battery-life figures are based on internal lab tests for typical-use scenarios; this is not an independent real-world test or a guarantee of your runtime.

The cited sources do not provide a comparable Watch8 Classic runtime figure. Do not infer a specific number of hours or days for either watch from capacity alone. Settings and usage affect how long a watch lasts.
Water resistance and durability
Samsung’s comparison lists the Watch8 Classic at up to 50m, with IP68 and MIL-STD-810H ratings. It lists the Ultra at up to 100m, also with IP68 and MIL-STD-810H. These are manufacturer ratings, not activity-specific guarantees. Check Samsung’s guidance for the exact activity you plan to do, and do not treat a rating as proof that a watch is suitable for every water sport or condition.
