Meet the Fitbit Sense 2 — your potential new swimming companion that moonlights as a meditation master. Though fair warning: this relationship comes with some interesting quirks!
Fitbit Sense 2  | Why I love it

Sporting a svelte new figure at $249.95, this tracker has clearly been hitting the gym. Picture your high school friend at the 10-year reunion — 10% thinner, 15% lighter, and somehow looking better than ever.
This fitness tracker is rated water-resistant up to 50 meters, making it suitable for a variety of aquatic activities. However, while it can track your swimming duration, it falls short when it comes to advanced metrics like stroke count, lap efficiency, or detailed swim analysis. If you’re looking for a device that goes beyond basic tracking, you may need to explore other options that offer more comprehensive swim-focused features.
Let’s peek under the hood of this tech marvel:
- Waterproof capabilities (up to 50 meters)
- A stress sensor
- Heart rhythm tracking
- Plays nice with both iPhone and Android
- A physical button
| Feature | Details |
| Water Resistance | 50 meters |
| Battery Life | 6 days typical use |
| Display | 1.58-inch AMOLED |
| Weight | 15% lighter than previous gen |
| Price | $249.95 |
When it comes to swimming features, the Sense 2 has its limitations. Unlike its predecessor, it doesn’t support lap counting, which may disappoint serious swimmers looking for detailed performance metrics. For those who prioritize advanced swim tracking, this device may feel more like an expensive stopwatch than a comprehensive training tool.
Where the Sense 2 truly shines is in its stress management capabilities. The EDA (electrodermal activity) sensor is highly responsive, detecting stress levels with impressive accuracy. It’s a standout feature for users who value mindfulness and wellness alongside their fitness goals.
This device is ideal for multi-sport enthusiasts who engage in a variety of activities, from swimming and yoga to hiking. Its automatic activity recognition is fast and reliable, seamlessly tracking your workouts without requiring manual input.
However, it’s important to note that while the Sense 2 performs well in water, it’s not designed for high-temperature environments like saunas or hot tubs. To ensure its longevity, it’s best to avoid exposing it to extreme heat.
Apple Watch Series 10
The Apple Watch Series 10 is a game-changer for fitness enthusiasts, especially those who prioritize water-based activities. This isn’t just another water-resistant smartwatch—it’s a sophisticated aquatic companion designed to elevate your swimming and underwater experiences. With its advanced features, the Series 10 transforms your wrist into a powerful tool for tracking and optimising your performance in the water.

Rated for depths of up to 50 meters, the Series 10 is built to handle swimming and other moderate water activities with ease. However, it’s not recommended for high-impact water sports like water skiing or diving, as it’s optimised for more controlled environments.
Powered by the next-generation S10 chip, this device delivers faster processing speeds and smoother performance, making previous models feel outdated by comparison. The display is equally impressive, offering up to 2,000 nits of brightness, ensuring crystal-clear visibility even in direct sunlight.
For swimmers, the Series 10 introduces a suite of advanced features:
- Intelligent Stroke Detection: Accurately identifies and tracks your swimming strokes, providing insights comparable to a professional coach.

- Sets and Splits Tracking: Offers detailed metrics for each segment of your swim, perfect for analyzing performance.
- Water Lock Feature: Prevents accidental screen touches and expels water from the speaker after your swim.
- Comprehensive Post-Swim Stats: Delivers in-depth data to help you refine your technique and track progress.
The Series 10 also excels in battery life, offering up to 18 hours of regular use. With Low Power Mode enabled, you can extend this to 36 hours, ensuring the watch keeps up with your active lifestyle. After a full day of workouts, you’ll still have around 35% battery remaining.
On the health and wellness front, the Series 10’s sensors have been upgraded for unparalleled precision. From heart rate monitoring to advanced workout tracking, this device eliminates the inconsistencies of older models, providing reliable data you can trust.

A quick tip: Rinse your watch with fresh water after swimming to maintain its longevity. Avoid exposing it to soaps or shower products, as these can compromise its water seals.
The Series 10 is available in a variety of finishes to suit your style:
- Aluminum: Pink, Midnight, Starlight, Silver, (PRODUCT)RED
- Stainless Steel: Gold, Silver, Graphite
While it’s perfect for swimming and everyday fitness tracking, it’s not designed for extreme activities like deep-sea diving. For most users, however, the Series 10 strikes an ideal balance of performance, durability, and style.

Battery life is another strong suit of the Forerunner 265. It lasts up to 13 days on a single charge in smartwatch mode, or 4 days with the always-on display enabled. While the latter reduces battery life, it’s a trade-off worth considering for those who prioritize real-time data visibility.
