Garmin managed to pivot seamlessly into the smartwatch and fitness tracker space once they lost their grip on the GPS market to newly-ubiquitous smartphones. They make solid and durable wearable devices that monitor a host of biometric information, interface with your mobile phone, store and play music, geolocate with multiple satellites and more. They're super cool, and thanks to Amazon's Big Deal Days, some of the best models are on sale for awesome discounts right now.

We've highlighted a handful of exceptional Garmin deals for this two-day event, but if you're not sure what you're looking for, we have a comprehensive guide to Garmin devices right here.

Throw in more than 20 preloaded sports apps and it's a keeper, especially for 52 per cent off.

There are discounts on a number of Garmin devices. We're particularly fond of the Instinct 2X Solar, which has loads of cool features, durable construction and can draw sustenance from the sun. But we also rate the Venu, which is a lot more affordable than the other devices we've picked, with a color LCD screen and lots of extremely cool fitness tracking apps. A more traditional profile comes with the Vivoactive 4S, which excels at motivating you to get your body moving. All really solid watches.

Which Garmin watch model should I buy?

With so many models available, it can be confusing when considering which Garmin model you should buy. The most important thing is to think about what you'll actually use it for and how many features you actually need.

Garmin divides its range in a number of categories, which basically break down as follows:

Garmin Fenix: Premium multisport watches for those who want the best of everything.

Garmin Venu: Garmin's smartwatch line, providing an alternative to the Apple Watch and others.

Garmin Forerunner: Top-tier GPS sports watches with a focus on catering for runners. This is the most attractive to runners or those principally focused on exercise, and the higher the number, the further up the scale it is.

Garmin Vivoactive: Everyday fitness watches that are best for gaining basic insights into all kinds of activity.

Garmin Vivomove: Hybrid watches that can track activity discreetly.

Garmin Instinct: Rugged GPS watches designed for the outdoors.

There are some devices outside this mainstream lineup - like the Epix - but these are the most common sub-brands to think about.

How should I choose which Garmin watch is best for me?

Take some time to see what is on offer: at a basic level, all Garmin devices will offer you heart rate tracking and GPS, and most will work with a wide ecosystem of devices - but some have much more advanced metrics to help you get the most from your training or offer better tracking options and battery life for longer adventures.
