Let’s compare these two head-to-head so you can decide: is the Apple Watch worth the extra $150?

2. 10-Day Battery Life > Daily Charging

• Apple Watch SE lasts just 18 hours—meaning nightly charging is a must.

Whether you’re traveling, camping, or just tired of charger anxiety, this is a game-changer. It even includes a 60-day power-saving mode for basic use.

3. Fitness & Health Features That Go Beyond

Unlike the Apple Watch SE, which limits sports modes and lacks blood oxygen monitoring, the M6 Ultra offers a full wellness suite:

• Blood Oxygen (SpO₂) Monitoring
• Stress Detection
• Guided Breathing Exercises

110+ Sports Modes, including:

• Running, cycling, swimming
• Hiking, badminton, yoga
• Even chess and e-sports mode!

This makes it ideal for fitness enthusiasts and casual users alike.

4. Works Flawlessly with iPhone (and Android)

Even though it’s not made by Apple, the M6 Ultra delivers seamless iOS integration, including:

• Call and message notifications
• Quick reply options
• Music playback control
• Customizable watch faces via app

Bonus: Unlike the Apple Watch, the M6 Ultra also works with Android—making it more flexible for multi-device households.

Who Should Buy the Apple Watch SE Instead?

We love the WalkerFit M6 Ultra, but there are cases where the Apple Watch SE might be a better fit:

✔ You need Apple Pay for everyday purchases
✔ You require ECG or fall detection for health/safety reasons
✔ You want deep Apple ecosystem integration, like unlocking your Mac

For those use cases, the SE delivers—but otherwise, M6 Ultra wins on value.
