The smartwatch market has come a long way in just a few years, and Samsung remains at the forefront of that evolution. From the sturdy Gear S3 to today’s refined Galaxy Watch range, the brand continues to combine timeless design with cutting-edge innovation.
For UK users, the Samsung Galaxy Watch 4 Classic 46mm and Galaxy Watch6 Classic LTE represent two of the most advanced wearables available — stylish enough for the boardroom, powerful enough for the gym, and smart enough to make daily life just that little bit easier.
At KEUBE, we’ve tested these watches in real-world conditions — from rainy London runs to busy commutes on the Northern Line — and here’s our complete take on how these two icons redefine the smartwatch experience.
1. The Galaxy Watch4 Classic 46mm — Where Smart Meets Timeless
When Samsung launched the Galaxy Watch4 Classic, it aimed to deliver the perfect blend of sophistication and practicality. With its stainless-steel body and physical rotating bezel, the 46mm Classic feels more like a luxury timepiece than a piece of wearable tech.
Design Built to Last
The first thing you notice about the Watch4 Classic is its craftsmanship. The stainless-steel case offers durability with a polished premium finish, while the Gorilla Glass DX-protected AMOLED display provides clarity even under the unpredictable British sunshine.
Available in Silver and Black, the watch can easily shift from a morning jog around Hyde Park to a client meeting in Canary Wharf. Many UK professionals have praised the 46mm model for its comfort during long wear, saying it “feels substantial without being bulky.”
Rotating Bezel — A True Classic Feature
Samsung’s decision to retain the physical rotating bezel was a masterstroke. It allows effortless scrolling through menus and apps — no more smudging the display mid-workout. One user we spoke to, Mark from Manchester, described it as “the perfect tactile balance between digital and mechanical — it’s the bit that makes me love wearing it every day.”
2. Health and Wellness at Your Fingertips
Health tracking is now central to the smartwatch experience, and the Galaxy Watch4 Classic introduced Samsung’s BioActive Sensor, a 3-in-1 marvel that combines optical heart rate, electrical heart monitoring, and bioelectrical impedance analysis in one compact chip.
Body Composition Analysis
The standout feature remains Body Composition measurement — something that was once exclusive to professional gym equipment. Within 15 seconds, the watch can provide readings for:
-
Skeletal muscle mass
-
Basal metabolic rate
-
Body water percentage
-
Body fat percentage
Personal trainers across the UK have started using this function to help clients monitor progress between sessions. At KEUBE, we tested it over four weeks, comparing results with gym-grade InBody scans — and the accuracy was within 3–5%, an impressive achievement for a wrist-based sensor.
Sleep & Stress Tracking
Samsung has improved sleep tracking dramatically. The Watch4 Classic not only records sleep stages but also analyses snoring patterns and blood oxygen levels throughout the night. For those working late or dealing with irregular schedules, the Sleep Score feature helps users identify exactly what affects rest quality.
Stress management, heart rate zones, and guided breathing sessions round off an impressive wellness toolkit — perfect for busy Londoners balancing work, fitness, and recovery.
3. Seamless Connectivity: Wear OS + One UI Watch
The Galaxy Watch4 Classic was the first to feature Wear OS Powered by Samsung, built in collaboration with Google. This combination brought the best of both worlds: Samsung’s hardware precision and Google’s rich app ecosystem.
Google Integration
Now, UK users can enjoy Google Maps, Google Pay, Google Keep, and YouTube Music directly from their wrist. Whether you’re navigating central London or grabbing a coffee using contactless payment, it’s all fast, intuitive, and secure.
The One UI Watch interface syncs automatically with your paired phone. Install WhatsApp, Strava, or Calm on your Galaxy smartphone, and they’ll appear instantly on your watch — no extra setup required.
Bixby, Gestures, and Smooth Performance
The rotating bezel is complemented by intuitive gesture controls: lift your wrist to answer a call or twist twice to dismiss notifications. Powered by Samsung’s Exynos W920 5nm processor and 1.5GB RAM, the Watch4 Classic handles multitasking fluidly.
Even during intensive sessions — navigating with Google Maps while streaming Spotify — the watch remains impressively responsive.
4. Real-World Case Study: The British Commuter Test
To understand real usage, we lent a Galaxy Watch4 Classic 46mm LTE to a user in Birmingham for two weeks.
Here’s what she found:
“I cycle to work most days, and I used to rely on my phone for navigation. With Google Maps on the Galaxy Watch, I can now keep my phone safely tucked away. The rotating bezel lets me zoom in and out of routes easily. The only drawback was the battery — I get around 36 hours before a recharge, but the fast charge does help.”
This echoes wider user feedback across the UK — performance and convenience are excellent, but battery life on LTE models remains around 1.5 days.
5. Galaxy Watch6 Classic LTE — Refining the Experience
Fast forward to 2025, and the Galaxy Watch6 Classic LTE builds upon everything the Watch4 Classic pioneered. While the Watch4 Classic remains a fantastic value, the Watch6 LTE is the polished evolution for those who want uncompromising performance.
Design Evolution
Samsung returned to the rotating bezel after removing it in the Watch5 Pro, acknowledging user demand. The Watch6 Classic offers a slimmer frame, brighter display (up to 2000 nits), and even more premium feel.
It’s available in 43mm and 47mm sizes, with new hybrid eco-leather straps and custom watch faces that adapt automatically to your outfit.
Performance Boost
The LTE model now runs on the Exynos W930 chipset, offering a 20% CPU boost and improved energy efficiency. Samsung claims up to 40 hours of use even with LTE enabled — a clear upgrade for users who found the Watch4’s battery limited.
Wellness Upgrades
The Watch6 Classic refines Samsung’s sleep tracking further, integrating with Sleep Coaching in Samsung Health — and it automatically adjusts your SmartThings devices for optimal rest (like dimming lights or setting the thermostat).
The temperature sensor, first introduced in the Watch5, now enhances cycle tracking and skin temperature analysis — features that appeal to both fitness and health-conscious users across the UK.
6. LTE Connectivity: Freedom Without a Phone
One of the biggest draws of both models — especially the Galaxy Watch6 Classic LTE — is standalone connectivity. Paired with EE, Vodafone, or O2, you can take calls, stream Spotify, and send texts directly from the watch.
However, earlier LTE models (like the Watch4 Classic) had some overheating issues during summer use. We recreated these tests in July conditions in London — around 28°C — and while the Watch4 Classic did warm up during long LTE Spotify sessions, the Watch6 Classic stayed cool, thanks to improved thermal management and processor efficiency.
7. User Reviews: What People Across the UK Are Saying
Hannah, London (Watch4 Classic 46mm):
“I’ve worn mine almost daily since 2022. The rotating bezel is still the best feature on any smartwatch. It looks elegant with both formal and casual outfits.”
James, Glasgow (Watch6 Classic LTE):
“The LTE model finally works properly! I can leave my phone at home on runs and still take calls. Battery lasts about two days, which is plenty for me.”
Priya, Bristol (Upgraded from Watch4 to Watch6):
“Sleep tracking accuracy has definitely improved. It’s much smoother, and the watch face customisation makes it feel new every day.”
