If you're a serious athlete that's been looking for a powerful multisport fitness watch, odds are you've stumbled across Garmin's fe?nix line of devices. While they are quite pricey, the fe?nix 3 line has proven to be one of the most powerful multisport watches on the market.

Garmin's Fenix 5 is an impressive smartwatch for people serious about fitness or the outdoors, but probably both too much and too little for people expecting something like the Apple Watch.

First time buyer of the Fenix series multisport watch. Fit and finish is very impressive. It looks and feels like an expensive watch (which is good, because it's certainly not inexpensive). Stylish to wear with a suit or out for a Sunday run.

Solid look and feel - Can track everything you throw at it - Golf GPS built in (works awesome) - Super strong battery life

- HR monitor can be inaccurate at times - Questionable calorie burn data compared with Fitbit Charge - Limited "app" store for customization; but if you're buying this watch it's not to play games or respond to texts

If you're an avid runner or cyclist, there's a good chance that either you or someone you know well is sporting a Garmin watch. Over the past few years, the company's reputation for building the best sports-tracking wearables has grown.

Amazing battery life; solid build quality; huge range of sports tracking and features; reliable performance

Might be big for some; proprietary 22mm QuickFit bands only; screen doesn't look great

Garmin's Fenix watches are a smart choice for fitness fanatics & adventurers with GPS, sports tracking and waterproofing but they don't come cheap.

Loved with Fenix 3, a great watch. This is a step above in all areas. Better functionality and whilst only a little bit smaller, it makes a huge difference. Feels even more premium as a product but retains the same qualities as its predecessor.

I've had a few of the Garmin watch range over the years and I upgraded to this. It's robust and smart looking. The screen is clear in both daylight and night. Not had a problem with any of the functions. It's a bit heavy compared with the forerunner equivilant. But this watch will take a knock.

Bought this after spending an age researching different products. Went for the Fenix 5 as it was on offer, and I didn't need the colour mapping. Been using it for a few weeks, and it's a great piece of kit. Tracks all my runs, rides etc really well and syncs seamlessly with Strava.

Fantastic watch. Lots of functionality. The Heartbeat tracking has about a 30 second delay so if you're really tracking it for HIT training get a chest strap.

I prefer the fenix 5's design to that of the $349 TomTom Adventurer , another go-anywhere GPS watch, which has a square face with a small d-pad below it. While there's nothing wrong with how the TomTom looks, it feels a bit out of place if you're wearing it in a more formal setting.

Durable design; Outdoor-readable display; Long battery life; Customizable display

Expensive; Low-resolution screen
