Best Samsung smartwatches: which Galaxy Watch should you buy?

Samsung Galaxy Watch 9 is the best all-round choice for most people because its light, slim case works from commuting to sleep. Choose the Galaxy Watch Ultra 2 for long outdoor sessions, the Watch 8 Classic for its rotating bezel, or the Watch FE for the simplest, least intimidating entry point.

Samsung Galaxy Watches at a glance

The Galaxy Watch 9 is the easiest model to recommend broadly, while the other watches earn their places through a specific control, endurance or price advantage.

The deciding factor is fit: choose the watch you can comfortably keep on overnight unless long outdoor sessions make the Ultra 2’s endurance-focused build more valuable.

Best overall - 1. Samsung Galaxy Watch 9

The Samsung Galaxy Watch 9 is best for commuting, everyday health tracking and sleep because it puts capable hardware into the slimmest case in this shortlist.

You can choose a 40mm case measuring 42.7 x 40.4 x 8.6mm or a 44mm case measuring 46.0 x 43.7 x 8.6mm. They weigh 31.5g and 34.0g respectively. That relatively low weight and 8.6mm depth matter when your sleeve catches the watch on a train, or when you roll onto your wrist in bed.

• Display: 1.34-inch or 1.47-inch, with up to 3,000 nits for a clear glance outdoors
• Battery capacity: 390mAh or 445mAh, depending on case size
• Storage: 32GB
• Controls: 2 buttons
• Water resistance: 5 ATM / IP68

The smaller version is the more natural choice if you have a narrow wrist or intend to track sleep every night. The larger case gives you more display area and battery capacity without moving into the bulk of the Classic or Ultra.

At the time of writing, the Samsung Galaxy Watch 9 costs £349 in its smaller size and £379 in its larger size. The catalogue of Samsung Galaxy Watch 9 straps includes silicone, nylon, leather, Milanese, metal and titanium, so the same watch can move from exercise to work without forcing you into one look or feel.

Who it suits: you want one Galaxy Watch for the commute, gym, notifications and overnight health tracking. Unless you regularly spend long training days away from a charger, this is the balanced choice.

Best for tactile controls - 2. Samsung Galaxy Watch 8 Classic

The Samsung Galaxy Watch 8 Classic is the right choice if a physical rotating bezel matters more to you than keeping the case light and unobtrusive overnight.

Its 46mm stainless-steel case measures 46.4 x 46 x 10.6mm and weighs 63.5g. You will notice that extra presence compared with either Watch 9 size, but it is part of the appeal if you prefer a more traditional watch shape and a control you can operate without covering the display.

• Display: 1.34-inch with up to 3,000 nits
• Battery capacity: 445mAh
• Battery with always-on display: up to 30 hours
• Storage: 64GB
• Controls: rotating bezel and Quick Button
• Water resistance: 5 ATM / IP68

The bezel is particularly useful when you wear gloves, have damp fingers or simply dislike repeated swipes on a small screen. It also gives the watch a dressier character. The trade-off is straightforward: this is substantially heavier than the Watch 9, so it is not the first model to choose for a small wrist or sensitive sleep.

At the time of writing, the Samsung Galaxy Watch 8 Classic costs £449. Available Samsung Galaxy Watch 8 Classic straps include silicone, nylon, leather, Milanese, metal and titanium, which lets you soften its sporty side or lean into the stainless-steel case.

Who it suits: you strongly prefer tactile navigation and a substantial, conventional-looking watch. If the rotating bezel is merely nice to have, the lighter Watch 9 is easier to live with around the clock.

Best for outdoor endurance - 3. Samsung Galaxy Watch Ultra 2

The Samsung Galaxy Watch Ultra 2 is the strongest option for serious hiking, running and long outdoor training, but most everyday buyers do not need its larger endurance-focused build.

The 47mm titanium case measures 47.4 x 47.1 x 10.7mm and weighs 61.5g. It is both wider and deeper than the Watch 9, so check how that footprint sits on your wrist rather than assuming the premium model will automatically feel better.

Its practical advantage appears once your training runs long: GPS battery runtime reaches up to 20 hours. Battery life with the always-on display active reaches up to 60 hours, backed by an 800mAh battery. Those are the figures that justify accepting the larger case if you track lengthy routes away from easy charging.

• Display: 1.52-inch, 498 x 498 and up to 5,000 nits
• Battery capacity: 800mAh
• GPS battery runtime: up to 20 hours
• Storage: 64GB
• Protection: Sapphire Crystal
• Water resistance: 10 ATM / IP69K
• Control: Quick Button

The brighter display is easier to read in direct sun, while the higher water-resistance ratings and titanium construction make more sense around demanding outdoor use. None of that makes the Ultra 2 automatically better for sleep, office days or a smaller wrist. Fit still wins there.

At the time of writing, the Samsung Galaxy Watch Ultra 2 costs £649. The available Samsung Galaxy Watch Ultra 2 straps span silicone, nylon, leather, Milanese and metal; nylon and silicone are the practical starting points when the watch will regularly get wet or sweaty.

Who it suits: you record long outdoor sessions, value a highly visible display in sunlight or spend enough time away from charging to use the extra endurance. For ordinary runs and gym sessions, Watch 9 remains the more comfortable all-rounder.

If your training revolves around route recording and social workouts, the next practical step is learning how to use Strava on Samsung Galaxy Watch.

Best entry point - 4. Samsung Galaxy Watch FE

The Samsung Galaxy Watch FE is the simplest route into Samsung’s watch platform if a compact case and lower price matter more than the newer hardware and larger displays elsewhere in the range.

Its 40mm aluminium case measures 39.3 x 40.4 x 9.8mm and weighs only 26.6g. That makes it particularly approachable on a small wrist. It is slightly deeper than the Watch 9, however, and its 1.2-inch display gives you less room for reading messages and workout information at a glance.

• Display: 1.2-inch at 396 x 396
• Battery capacity: 247mAh
• Processor: Exynos W920
• Storage: 16GB
• Display protection: Sapphire
• Water resistance: 5 ATM / IP68

The smaller battery capacity and storage are the clearest compromises, so the FE is better viewed as a focused entry point than a cheaper version of every premium feature. Its light case remains a genuine advantage if you dislike bulky watches or are buying a first smartwatch as a gift.

At the time of writing, the Samsung Galaxy Watch FE costs £199. You can find silicone, nylon, leather, Milanese and metal among the available Samsung Galaxy Watch FE straps, giving this simpler watch considerably more flexibility in comfort and appearance.

Who it suits: you want a compact first Galaxy Watch for notifications, everyday activity and health tracking without paying for the endurance build of the Ultra or the physical bezel of the Classic.

Which Samsung Galaxy Watch should you choose?

Choose by how long you will wear the watch, how it sits on your wrist and whether your outdoor sessions genuinely exceed the needs of the lighter models.

• If you wear your watch to bed: start with the Galaxy Watch 9, particularly the 40mm case. Its slim profile is less intrusive against bedding, and changing to a soft Samsung Galaxy Watch 9 40mm silicone strap can make overnight wear more practical.
• If you commute and train several times a week: choose Galaxy Watch 9. It balances readable displays, manageable weight and enough storage without putting an outdoor-focused case on your wrist all day.
• If you navigate by touch: choose Galaxy Watch 8 Classic. The rotating bezel is the reason to accept its heavier stainless-steel case.
• If you track long hikes or extended runs: choose Galaxy Watch Ultra 2. Its GPS runtime is the concrete advantage; its larger case is the cost.
• If you have a small wrist or are buying a first smartwatch: compare Galaxy Watch FE with the smaller Galaxy Watch 9. The FE is lighter and less expensive, while Watch 9 is slimmer and offers the more current all-round package.
• If appearance changes between work and training: prioritise the watch fit first, then change the strap. Each model here has both sporty and dressier strap materials available.

For most wrists, the answer comes back to Galaxy Watch 9: it is capable enough for regular exercise yet easier to keep on through commuting, work and sleep. Move to Ultra 2 only when outdoor endurance outweighs that everyday comfort; choose Classic for the bezel, or FE for a simpler start.

Frequently asked questions

Here are the practical compatibility and ownership answers to check before choosing your Galaxy Watch.

Should I choose Bluetooth or LTE?

Choose Bluetooth if your phone normally comes with you. Choose LTE if you want to make calls, send messages, stream music and use connected features while leaving your phone behind, with mobile service activated on the watch.

Will every health feature work with a non-Samsung Android phone?

No. Core Samsung Health tracking works with compatible non-Samsung Android phones, but ECG, irregular heart rhythm notifications and sleep apnea features require a compatible Samsung Galaxy phone.

Do Samsung Galaxy Watches work with an iPhone?

No. Current Galaxy Watch models that run Wear OS, including Galaxy Watch FE and newer Galaxy Watch generations, do not work with an iPhone.

Can I swim or shower with a Galaxy Watch?

If the watch is rated 5 ATM and IP68, it can be used for pool swimming and shallow water, but not diving, water sports or high-pressure water. Remove leather or hybrid bands first, then rinse and dry the watch after pool or sea water.

Do Samsung Health features require a subscription?

Core Samsung Health tracking does not require a subscription. Optional premium content powered by iFit requires a paid subscription.
