In today’s fitness-driven world, having a waterproof fitness tracker is no longer optional—it's essential. Whether you're swimming, training in the rain, or breaking a sweat at the gym, your device must endure every condition.
Among all the choices in 2025, the M6 Ultra Smartwatch by WalkerFit has emerged as a top contender. It’s affordable, feature-packed, and built to last—making it the best waterproof fitness tracker for everyday athletes and wellness seekers alike.
Why a Waterproof Fitness Tracker Like M6 Ultra Matters
Water is one of the biggest threats to wearable tech. Without proper protection, your device could stop working mid-workout. That’s why IP68 waterproofing is a must in modern fitness gear.
The M6 Ultra is certified IP68, meaning it can be submerged deeper than 1 meter for extended periods. Whether you’re swimming laps or out in a storm, your M6 Ultra continues tracking without interruption (learn more about IP ratings).
All-in-One Features: What Makes M6 Ultra Stand Out
- Looking for the best waterproof fitness tracker means evaluating not only water protection but also health and performance capabilities. Here’s what the M6 Ultra delivers:
- True Waterproofing (IP68): Ideal for swimming, rain, and sweat-heavy workouts.
- Up to 10-Day Battery Life: Long-lasting power for consistent daily use.
- Comprehensive Health Monitoring: Tracks heart rate, SpO₂, sleep patterns, and daily steps.
- 1.96” Full-View Display: Crisp visuals, even in sunlight.
- Seamless Sync: Fully compatible with both Android and iOS.
These features are usually reserved for premium models—but the M6 Ultra delivers them all for under $100.
Best Waterproof Smartwatch Under $100? Here’s the Proof
- A smartwatch under $100 often comes with compromises—either on display, battery, or tracking accuracy. But the M6 Ultra delivers:
- Durable IP68 waterproof protection
- Long battery runtime
- Real-time health metrics
- Accurate swimming and fitness tracking
- Comfortable, ergonomic design
It checks all the boxes. So if you’re comparing it with alternatives in this price range, the M6 Ultra beats them in value, performance, and reliability.
Waterproof Fitness Tracker for Swimming: Built for the Pool
For swimmers, not every tracker is created equal. Many wearables claim to be “splash-proof” but can’t truly handle immersion.
The M6 Ultra is different—it was designed with aquatic activity in mind:
- Tracks laps, strokes, distance, and calories burned
- Stays secure with a lightweight and adjustable strap
- Performs reliably underwater thanks to IP68 certification
If you want a waterproof fitness tracker for swimming that performs like a premium device, this is it.
Who Should Choose the M6 Ultra Smartwatch?
Whether you're a fitness beginner tracking daily steps or a competitive swimmer looking for accurate water-based metrics, the M6 Ultra adapts to your lifestyle. It’s perfect for:
- Busy professionals needing a reliable fitness tracker with health alerts

- Budget-conscious buyers who don’t want to sacrifice quality
