The Samsung Galaxy Watch Ultra 2 is Samsung’s most advanced outdoor smartwatch yet. Officially styled as the Galaxy Watch Ultra2, it combines a rugged titanium body, an 800mAh battery, a brighter display and specialised tools for running, cycling and diving.

Samsung announced the watch during Galaxy Unpacked in London on 22 July 2026. Although the design remains familiar, the company has made important changes to durability, performance, battery capacity and outdoor tracking.

Moreover, the Galaxy Watch Ultra 2 runs on Samsung’s latest wearable software and brings deeper Galaxy AI health insights to the wrist. Therefore, it targets serious athletes, outdoor explorers and Android users who want a premium alternative to specialist sports watches.

Galaxy Watch Ultra 2 Specifications

Samsung offers the Watch Ultra 2 in one 47mm LTE configuration. Consequently, buyers do not need to choose between several case sizes or connectivity options.

Galaxy Watch Ultra 2 Design

At first glance, the Watch Ultra 2 looks similar to Samsung’s previous Ultra watch. It retains the circular display inside a cushion-shaped titanium case, along with three physical controls on the side.

The Quick Button remains central to the design. Users can assign it to workout features, while holding it can activate the emergency siren.

In addition, Samsung continues to use sapphire crystal over the screen. The titanium body should provide better resistance against scratches, impacts and demanding outdoor conditions than a standard aluminium smartwatch.

Galaxy Watch Ultra 2 Colours

Samsung currently lists two main finishes:

• Titanium Grey
• Titanium Silver

Meanwhile, buyers can pair the watch with Marine, PeakForm and Trail bands in several colours. Band availability may differ by market and promotion.

The overall appearance remains rugged rather than minimal. Therefore, buyers who prefer a slim everyday watch may find the regular Galaxy Watch9 more comfortable.

Galaxy Watch Ultra 2 Display

In addition, Samsung has fitted the watch with a 1.52-inch Super AMOLED display protected by sapphire crystal.

More importantly, brightness now reaches up to 5,000 nits, compared with 3,000 nits on the previous Galaxy Watch Ultra. As a result, route information, heart-rate data and dive metrics should remain easier to read in strong sunlight or underwater.

The display also uses a high-contrast interface designed for outdoor visibility. Nevertheless, actual brightness will vary depending on content, battery conditions and automatic brightness settings.

Is the Screen Bigger?

Yes, but only slightly.

The Samsung Watch Ultra 2 uses a 1.52-inch display, while the previous Ultra had a 1.47-inch panel. Therefore, the difference may not transform everyday use, although it provides slightly more room for maps, health data and workout information.

Galaxy Watch Ultra 2 Battery Life

More importantly, Battery capacity represents one of the watch’s biggest upgrades.

Samsung has increased the battery to 800mAh, up from 590mAh in the earlier Galaxy Watch Ultra. In addition, the new model supports fast charging and can reach approximately 40% in around 30 minutes with the included charger.

Consequently, the watch should suit longer outdoor activities better than Samsung’s mainstream smartwatch models.

However, real-world battery life will depend on:

• LTE usage
• GPS activity
• Screen brightness
• Always-on display
• Sleep tracking
• Health monitoring
• Workout duration
• App notifications

Continuous GPS, mobile data and high display brightness will reduce endurance more quickly. Even so, the larger battery gives Samsung more room to support long trail runs, cycling sessions and outdoor navigation.

Snapdragon Wear Elite Performance

The Samsung Watch Ultra 2 uses Qualcomm’s Snapdragon Wear Elite Platform.

Samsung says the processor improves app launch speed, responsiveness and general interaction. Therefore, menus, health screens and third-party apps should feel faster than on previous Galaxy watches.

Furthermore, the watch includes 2GB of RAM and 64GB of internal storage. The storage can hold apps, downloaded music, routes and offline content.

Although benchmark results will reveal the full performance difference, the processor upgrade should also support more advanced health analysis and Galaxy AI features.

Galaxy Watch Ultra 2 Durability

Furthermore, Samsung designed the watch for difficult environments.

It carries:

• IP69K dust and water resistance
• 10ATM water resistance
• MIL-STD-810H durability
• EN13319 diving certification
• Titanium construction
• Sapphire crystal protection

The IP69K rating adds resistance against dust and high-pressure water jets. Meanwhile, the 10ATM rating supports water pressure associated with deeper swimming and outdoor water activities.

Most importantly, the Samsung Watch Ultra 2 is Samsung’s first watch to meet the EN13319 standard for diving instruments.

However, users should still follow Samsung’s care instructions. Water resistance can decline over time, especially after impacts, repairs or exposure to unsuitable chemicals.

Galaxy Watch Ultra 2 Diving Features

For example, Diving support is one of the most distinctive Watch Ultra 2 features.

The watch can track dives down to 40 metres, or approximately 130 feet. During a dive, the Depth app can display:

• Current depth
• Water temperature
• Elapsed dive time

Moreover, Samsung worked with diving equipment company Mares on its underwater features. The watch begins tracking when the user enters the water and displays essential information in real time.

Therefore, recreational divers may find the Ultra 2 more useful than a conventional smartwatch.

Nevertheless, serious divers should check whether its functions meet their specific training, certification and safety requirements before relying on it as their only instrument.

Better Trail Running Tools

Samsung has expanded its trail-running experience with navigation, elevation and hydration features.

Users can load GPX routes and follow turn-by-turn directions through the watch’s built-in GPS. In addition, Climb Guidance shows upcoming elevation gain and average gradient, helping runners adjust their pace before difficult sections.

The Water Intake Alarm can also estimate when runners should drink during a session.

Meanwhile, Trail Run tracking records elevation, climbing progress and terrain impact. Therefore, runners can review more than basic distance and pace data.

Track Back and Route Navigation

Track Back can guide users along the route they previously travelled.

This feature may prove especially useful during hiking, cycling and trail running in unfamiliar locations. However, users should still carry suitable navigation tools and avoid relying on a smartwatch alone in remote areas.

Galaxy Watch Ultra 2 Cycling Features

The Samsung Watch Ultra 2 can connect directly to compatible cycling sensors without requiring the phone to act as an intermediary.

As a result, cyclists can view:

• Cadence
• Power
• Speed
• Heart rate
• Personalised heart-rate zones

The watch also supports GPX routes, climb guidance and Race Yourself. The latter lets cyclists compare their current effort with previous performance in real time.

Furthermore, Samsung has integrated Strava support, although some Strava features may require a paid subscription.

Galaxy Watch Ultra 2 Health Features

Samsung has positioned the watch as both an adventure device and a continuous health companion.

Its sensor package includes:

• Optical heart-rate sensor
• Electrical heart sensor for ECG
• Bioelectrical impedance analysis
• Blood oxygen sensor
• Temperature sensor
• Accelerometer
• Gyroscope
• Barometer
• Compass

These sensors support a broad range of Samsung Health features.

Energy Score

Energy Score uses sleep, activity and heart-related data to estimate how prepared the user may be for exercise or recovery.

For example, the watch may suggest a demanding session after strong recovery data. On the other hand, it may recommend lighter activity after poor sleep or unusually high strain.

Fitness Index

Fitness Index reviews body composition and workout history to generate a personalised assessment of physical condition.

Therefore, users can follow changes over time rather than relying on one isolated measurement.

Vitals

Vitals analyses heart rate, heart-rate variability, respiration, temperature and blood oxygen information.

The system looks for changes from the user’s typical pattern. Consequently, it may help users notice when their body appears different from normal.

Heart Health Score

Samsung also provides broader heart-health insights based on tracked signals.

However, health features should not replace professional diagnosis or medical treatment. Availability can also differ by region because some tools require regulatory approval.

Sleep Tracking and Sleep Apnoea

The Watch Ultra 2 includes Samsung’s Sleep Coaching system.

Users wear the watch for several nights to establish a sleep profile. Afterward, the software recommends gradual changes designed to improve habits and sleep quality.

In supported regions, the watch can also look for signs associated with moderate to severe obstructive sleep apnoea by analysing blood oxygen data during sleep.

Nevertheless, this feature does not provide a medical diagnosis. Anyone who receives an alert or experiences ongoing symptoms should consult a qualified medical professional.

Galaxy AI Features

Galaxy AI helps turn tracked information into more understandable recommendations.

Instead of showing only raw numbers, the watch can connect sleep, exercise and recovery data. As a result, users receive guidance through features such as Energy Score, Wellness Tips and daily health summaries.

Moreover, Samsung designed the watch to work closely with the Samsung Health app on a compatible Galaxy phone. Users can review trends, workouts and sleep information on a larger screen.

Some features may require a Samsung account, a compatible phone or an internet connection.

Emergency and Safety Tools

The Galaxy Watch Ultra 2 includes several safety features for outdoor users.

Emergency Siren

Holding the Quick Button for five seconds activates an 86-decibel siren.

Samsung says the sound can travel up to 180 metres in suitable conditions. Therefore, it may help attract attention after an accident or during an emergency.

Fall Detection

The watch can identify a hard fall and check whether the user needs assistance.

If the user does not respond, the system can contact an emergency service or saved contact, depending on settings and regional support.

Emergency SOS

Five presses of the Home button can activate Emergency SOS.

However, emergency features depend on network availability, correct setup and location support. Users should configure their emergency contacts before travelling.

Galaxy Watch Ultra 2 Software

The watch runs Wear OS powered by Samsung, combined with Samsung’s One UI Watch interface.

This provides access to:

• Samsung Health
• Google Maps
• Google Wallet
• Samsung Wallet
• Google Play Store apps
• Music and podcast apps
• Messaging notifications
• Third-party fitness services

Additionally, LTE connectivity allows selected features to work without a nearby phone, although carrier support and separate mobile plans may be required.

Galaxy Watch Ultra 2 vs Original Galaxy Watch Ultra

The larger battery and brighter display represent meaningful upgrades. In addition, the new diving certification creates a clearer reason for water-sport users to choose the Ultra 2.

However, existing Galaxy Watch Ultra owners who mainly track everyday workouts may not need to upgrade immediately.
