Apple Watch SE 3 vs Garmin Forerunner 70: Quick Comparison

Battery figures are manufacturer estimates under specified usage conditions. Actual performance varies with settings, display use, GPS mode and connected features.

1. Design and Everyday Comfort

Both watches are designed to be comfortable during everyday wear and exercise, but their approaches to design are noticeably different.

Apple Watch SE 3: A Smartwatch for Everyday Life

The Apple Watch SE 3 keeps Apple’s familiar rectangular design with an aluminum case, rounded edges and interchangeable bands. It is available in 40mm and 44mm sizes, giving buyers options for different wrist sizes.

Its always-on OLED display makes it easy to check the time, notifications and activity information without raising your wrist. The interface is built around watch faces, widgets, apps and quick controls, so the watch feels like a natural extension of an iPhone.

You can personalize its appearance with different watch faces and bands, making it suitable for workouts, workdays and casual occasions.

The design is familiar rather than dramatically new, but the always-on display and S10 chip make the SE 3 a more capable everyday smartwatch than its predecessor.

Garmin Forerunner 70: Built Around Running and Training

The Garmin Forerunner 70 takes a more athletic approach. Its lightweight design is intended to stay comfortable during runs, workouts and daily activity tracking.

The AMOLED display provides colorful workout information, while physical buttons make it easier to navigate menus and training screens during exercise. This combination is useful when your hands are sweaty or you do not want to rely entirely on touchscreen controls.

Garmin also provides customizable data screens, allowing runners to keep pace, distance, heart rate and other workout information visible while training.

The Forerunner 70 looks more like a dedicated sports watch than a lifestyle accessory. Its design prioritizes workout usability over the extensive personalization and app experience offered by Apple.

Which Watch Is More Comfortable?

Both are lightweight options for everyday wear. The better choice depends on wrist size, preferred display shape and how you use a watch during exercise.

The Apple Watch SE 3 is a natural fit for buyers who prefer a compact lifestyle smartwatch. Garmin is worth considering if physical buttons, dedicated running screens and a sport-oriented design are more important.

2. Fitness Tracking and Running Features

Fitness tracking is one of the most important differences between these watches. Both can record everyday activity and workouts, but Garmin places more emphasis on training analysis.

Garmin Forerunner 70: More Running-Focused Training Tools

The Forerunner 70 is designed for people who want more than basic step counts and workout summaries.

Its running and training features include:

• Running activity tracking and pace information
• VO2 max estimates
• Training readiness insights
• Race predictions
• Training status and recovery information
• Customizable run and walk alerts
• Workout planning and training support through Garmin Connect

These features help runners understand their training patterns and make more informed decisions about workout intensity and recovery.

Garmin’s training tools are particularly useful for people following a running schedule, preparing for an event or gradually increasing their weekly mileage.

However, not every metric should be treated as a medical measurement or a definitive assessment of fitness. Training and recovery estimates are most useful when considered alongside how you feel, your sleep and your actual workout performance.

Apple Watch SE 3: Flexible Fitness Tracking for Everyday Users

The Apple Watch SE 3 offers a capable workout experience through Apple’s Workout app.

It tracks activities such as running, walking, cycling, swimming, strength training, yoga and other exercise types. Users can monitor heart rate, workout duration, pace, distance and activity progress.

Additional running tools include:

• Custom workouts
• Heart-rate zones
• Pace and target alerts
• VO2 max estimates
• Running power and cadence information
• Training Load
• Post-workout heart-rate information

The Apple Watch also works with third-party fitness apps, including services such as Strava and Nike Run Club. This gives users more flexibility if they already follow a particular training platform.

For casual runners, gym users and people who want to stay active, the SE 3 provides plenty of useful information. However, Garmin’s dedicated training and recovery environment is better suited to runners who want more detailed guidance built into the watch.

Workout Tracking: Which One Should You Choose?

The Apple Watch SE 3 is a strong option for people who participate in different activities and want their workouts integrated with everyday smartwatch features.

The Garmin Forerunner 70 makes more sense when running is a regular part of your routine and you want structured training information rather than simply recording exercise sessions.

3. GPS Accuracy and Real-World Fitness Tracking

GPS and sensor performance can influence how useful a fitness watch becomes, particularly for runners who monitor pace, distance and progress over time.

Both watches include built-in GPS, but their tracking results can vary depending on the environment, satellite conditions, wrist movement and workout type.

What Happened in a 5,500-Step Comparison?

A Tom’s Guide comparison published in May 2026 tested the Apple Watch SE 3 and Garmin Forerunner 70 during a walk targeting 5,500 steps. The reviewer wore one watch on each wrist, manually counted steps and used Strava on an iPhone as a reference for distance, pace and elevation.

The results were:

The Garmin recorded a step count closer to the manual total, while Apple’s distance and elevation readings were closer to the Strava reference in this particular walk.

One notable difference was elevation tracking. The Apple Watch SE 3 includes an always-on altimeter, while the Forerunner 70 does not have an onboard barometric altimeter. This is relevant when tracking routes with significant elevation changes.

The test does not establish that one watch is universally more accurate. It does show that both can produce useful everyday tracking results, with differences depending on the measurement.

What this means for buyers: Garmin remains attractive for dedicated running features, but the Apple Watch SE 3 should not be dismissed for everyday GPS workouts. If elevation tracking is especially important, Apple’s built-in altimeter is a useful advantage.

4. Health Monitoring and Wellness Features

The Apple Watch SE 3 and Garmin Forerunner 70 both monitor health-related information, but they present it differently.

Apple focuses on accessible health notifications and everyday wellness information. Garmin emphasizes fitness trends, recovery and how your body responds to training.

Apple Watch SE 3: Everyday Health Features

The Apple Watch SE 3 includes several useful health and wellness features:

• High and low heart-rate notifications
• Irregular rhythm notifications
• Wrist-temperature sensing
• Sleep stages and sleep score
• Sleep apnea notifications
• Cycle Tracking features
• Noise monitoring

One important limitation is that the SE 3 does not include the ECG app or Blood Oxygen app. Buyers looking for those specific capabilities should consider a different Apple Watch model.

Its sleep apnea notifications and irregular rhythm notifications are also not substitutes for a medical diagnosis. They are intended to provide information that may help users decide when to seek professional advice.

For everyday users, the SE 3 provides a straightforward way to monitor activity, sleep and selected health indicators through Apple’s Health app.

Garmin Forerunner 70: Recovery and Training Insights

Garmin takes a more performance-oriented approach to health tracking.

The Forerunner 70 provides information such as:

• Heart-rate tracking
• HRV status
• Stress monitoring
• Sleep stages and sleep score
• Body Battery energy monitoring
• Recovery time
• Training readiness
• Training and health status

These features can help runners understand how their activity, sleep and recovery patterns relate to their training routine.

For example, Body Battery provides an estimate of available energy based on factors such as stress, activity and sleep. Training readiness combines several indicators to help users assess whether they may be prepared for another demanding session.

These are estimates rather than clinical measurements. They should be used as supporting information, not as a replacement for medical advice or personal judgment.

Which Watch Is Better for Health Tracking?

The Apple Watch SE 3 is a good fit for users who want accessible health notifications and everyday wellness features.

The Garmin Forerunner 70 is more appealing to people who want to understand training load, recovery patterns and fitness-related trends.

The better choice depends on whether your priority is general health awareness or performance-oriented tracking.

5. Sleep Tracking and Recovery

Sleep tracking is available on both watches, but the information is presented with different goals in mind.

The Apple Watch SE 3 records sleep stages and provides a sleep score. It also supports sleep apnea notifications, giving users additional information about their sleep patterns.

Garmin offers sleep stages, sleep scores and recovery-related insights. Its Body Battery and HRV information can help users understand how sleep and daily stress may affect their readiness for exercise.

For someone who simply wants to understand sleep duration and general sleep patterns, Apple’s presentation is straightforward.

For runners who want sleep information connected to training and recovery, Garmin provides a more integrated set of performance tools.

Neither watch should be treated as a substitute for a clinical sleep assessment.

6. Battery Life: Garmin Has a Clear Advantage

Battery life is one of the strongest reasons to consider the Garmin Forerunner 70.

Apple estimates up to 18 hours of normal use for the SE 3, or up to 32 hours in Low Power Mode. It also supports fast charging, which can help reduce charging interruptions.

The Forerunner 70 offers considerably longer endurance:

These figures are not directly equivalent because the manufacturers use different testing methods and usage assumptions.

In practical terms, Apple is generally a daily-charging smartwatch. Garmin can last several days or longer between charges, depending on display and GPS settings.

That difference matters for runners who regularly record long workouts, people who track sleep every night and travelers who prefer not to carry a charger.

Battery verdict: Garmin Forerunner 70 is the clear choice if longer battery life is a major buying priority.

7. Smart Features, Apps and Phone Compatibility

The Apple Watch SE 3 and Garmin Forerunner 70 offer different levels of smartwatch functionality.

Apple Watch SE 3: A More Complete Smartwatch Experience

The SE 3 is designed to work closely with an iPhone. Its smart features include:

• Calls and message notifications
• Siri
• Apple Pay
• App Store access
• Music controls and playback
• Calendar and reminders
• Smart notifications
• Safety and emergency features

The S10 chip and watchOS experience allow the SE 3 to run apps and manage everyday tasks directly from the wrist.

It is especially useful if you already use Apple services and want your watch to work smoothly with your phone.

Garmin Forerunner 70: Practical Connectivity for Active Users

The Forerunner 70 supports smartphone notifications and media controls when connected to a compatible phone. It also offers Garmin Connect for viewing workout information, activity trends and training data.

Its connected features include:

• Smartphone notifications
• Media controls
• Garmin Connect synchronization
• LiveTrack location sharing
• Incident Detection
• Compatible third-party app support through Connect IQ

However, Garmin does not offer the same communication and app experience as Apple. It does not provide the same wrist-based calling, Apple Pay or broad app ecosystem.

The Garmin watch is designed to complement your phone rather than replace it.

iPhone vs Android Compatibility

This is an important buying consideration.

The Apple Watch SE 3 requires an iPhone and is not designed to pair with Android phones.

The Garmin Forerunner 70 works with compatible Android and iOS devices. This makes it a more flexible option if you use an Android phone or may switch phone platforms in the future.

If you own an iPhone and want a watch that feels fully integrated with it, Apple has the advantage. If you want the same fitness-focused watch experience across different phone platforms, Garmin is more flexible.

8. Safety Features

Both watches offer safety-related tools, although their capabilities and setup requirements differ.

The Apple Watch SE 3 includes:

• Emergency SOS
• Fall Detection
• Crash Detection
• Check In

These features can help users contact emergency services or share information with selected contacts in supported situations. Availability and functionality may depend on region, connectivity and setup.

Garmin offers Incident Detection and LiveTrack. These tools can help share location information or notify selected contacts during supported outdoor activities. A compatible paired phone and appropriate connectivity may be required.

If emergency features are a major reason for buying a smartwatch, check regional availability and the conditions required for each feature before purchasing.

9. Price and Overall Value

Both watches target buyers looking for a capable wearable without moving into the most expensive premium smartwatch category.

The Apple Watch SE 3 has a published starting price of $249 in the US, although retailer prices and cellular configurations can differ.

Garmin pricing should be checked against the current retailer listing before buying. Discounts, bundles and regional availability can change the value comparison.

Rather than choosing solely by the lowest price, consider what you will use most often.

The Apple Watch SE 3 offers more value if you want apps, notifications, communication and everyday convenience alongside fitness tracking.

The Garmin Forerunner 70 offers more value if you will use its running features, recovery tools and extended battery life regularly.
