7 of the best Fitness Watches #1 - Garmin Venu X1 GPS smartwatch

Under the hood, the Venu X1 packs in Garmin’s full suite of health and wellness tracking tools, including 24/7 heart rate monitoring, HRV status, advanced sleep tracking, Pulse Ox, Body Battery energy monitoring, and more. Whether you’re logging a run, hitting the golf course, or trying a new workout, the watch comes with over 100 preloaded sports apps. Runners will love the personalised training plans from Garmin Coach, while outdoor adventurers can take advantage of the built-in GPS and maps—plus, with an Outdoor Maps+ subscription, you can even download satellite imagery. It’s a watch that adapts to you, offering training readiness insights so you know when to push and when to rest.

7 of the best Fitness Watches #2 - Google Fitbit Charge 6 Activity Tracker

The Fitbit Charge 6 is a compact, feature-packed activity tracker built for everyday athletes and health-focused users. It offers up to seven days of battery life (actual runtime varies with use), 50m water resistance, built-in GPS, and broad compatibility with iOS (15+) and Android (9+). The Charge 6 tracks steps, Active Zone Minutes, 24/7 heart rate, SpO₂, ECG (where available), and includes Fitbit’s Daily Readiness Score and Cardio Fitness Level. It also brings deeper Google integration — Google Maps, Google Wallet, and YouTube Music controls — onto a bright, colour touchscreen, plus smartphone notifications and a range of exercise modes.

In daily use the Charge 6 shines as a comfortable, always-on health monitor. Customers report accurate heart-rate readings and useful sleep analysis (though the most detailed sleep metrics require Fitbit Premium). The built-in GPS and exercise tracking work well for most casual runs and rides, but a number of users have noted inconsistent running-pace data compared with dedicated GPS watches. Battery life is often cited as solid (many hit 4–7 days), yet a minority experience faster drain after prolonged heavy use. A few durability and connectivity issues were reported after months of use, and there are quirks such as heart-rate sensing failing over tattoos — something to test before you rely on it for critical monitoring.

Verdict: the Charge 6 is an excellent everyday fitness tracker for people who want strong health metrics, a lightweight design, and Google features without the bulk of a full smartwatch. Swap the stock strap for a breathable perforated band if you sweat a lot, and double-check your bank’s compatibility if Google Wallet is a must. If you’re a performance athlete after flawless GPS pace or extreme battery life, a sports watch might be a better fit — but for most users the Charge 6 hits an attractive balance of comfort, features and price.

7 of the best Fitness Watches #3 - AMAZFIT Bip 6 Smart Watch

The Amazfit Bip 6 Smart Watch delivers a strong combination of style, performance, and value, making it a compelling choice for anyone looking for an affordable yet feature-rich smartwatch. With its lightweight aluminium body and large 1.97" AMOLED display, it looks and feels far more premium than its price suggests.

Supporting over 140 workout modes, including HYROX Race and Strength Training, along with 50m water resistance, it’s designed to handle a wide range of activities. Accurate GPS tracking with five satellite systems ensures precision on runs, rides, and hikes, while the battery life of up to 14 days means you can go weeks without charging.

The size is also a hit, as it’s large enough for easy readability but not bulky enough to snag on clothing or equipment. A few minor criticisms include the inability to set a date of birth under 18 years old and a slightly clunky interface for downloaded maps, but these are seen as small trade-offs for the value offered.

For the price, the Amazfit Bip 6 is an outstanding smartwatch that punches well above its weight. It delivers a premium design, excellent health and fitness tracking, strong GPS performance, and exceptional battery life at a fraction of the cost of its high-end competitors. Whether you’re a seasoned athlete looking for reliable workout data, a casual user who wants a stylish everyday watch, or someone seeking a budget-friendly alternative to the big brands, this model stands out as one of the best-value options available.
