I'm a long-time Garmin user and these 10+ deals from Amazon Prime Big Deal Days are perfect for your summer workouts

(Image credit: Future) Amazon is back with another major sale event for 2026, Prime Big Deal Days, and the retailer brings a fresh batch of deals on Garmin devices over the next week.The standout deal I've found is a 50% discount on the excellent Garmin Epix Pro (Gen 2) Sapphire Edition for AU$829, which is a steal for what you're getting. Our review called it 'essentially an AMOLED-screened version of the flagship Fenix 7 Pro', and its Sapphire display makes it virtually indestructible.Amazon stocks a wide range of Garmin's offerings, like smartwatches and wearables, health-tracking devices, dash cams and dedicated GPS satellite navigation (sat nav) displays. The retailer is also where you can often find the best prices on these premium devices, and Prime Big Deal Days will see hefty discounts for even more savings.Some of the deals I've found were at some point among the best Garmin watches like the Vivoactive 5, Forerunner 965 and the ultra-rugged Instinct 2.Having used Garmin watches for years, I personally consider some of the brand's offerings the best smartwatches out there, prioritising fitness and health features with just enough smarts to be a capable extension of your smartphone.It’s worth noting that the best deals will be exclusive to Amazon Prime members (which I have labelled), so it’s worth re-subscribing if you were a past member. If it’s your first time, you can sign up for a 30-day free trial and still get access to these discounts.Whatever you’re looking for, whether it’s the top-of-the-line watch or you just need a replacement charging cable, there’s a Garmin deal for you at this year’s Amazon Prime Big Deal Days sale.Follow our dedicated live coverage of the Amazon Prime Big Deal Days 2026 sale for more deals and discountsBest Prime Big Deal Days 2026 Garmin deals in AustraliaPrime Day 2026 in Australia: sale informationWhen is Amazon Prime Big Deal Days 2026 in Australia?Taking place earlier than it did last year, Amazon Australia's Prime Big Deal Days 2026 sale kicks off at midnight East Coast time on Tuesday, September 29 and will run for seven days.

Amazon also stocks a limited range, but there’s still plenty to go around.How to choose the best Garmin watch for youWhen choosing a Garmin watch, there are three key points to consider: what sport you’re interested in, what level you are at, and your budget.If you're starting your fitness journey and want a watch to help improve your habits, that's fantastic – a Venu watch will suit you perfectly. They're small and discreet, making them great for all-day wear, and they offer a good range of general fitness tracking tools.Want something cheaper? The Garmin Vivoactive 6 will work very nicely for beginner runners and all forms of exercise, like fitness classes, and it's also great for sleeping in, as it's nice and light.If you’re a little bit further into your journey and now enjoy serious running, cycling, swimming or all of the above, the Forerunner 570 and 970 are superb triathlon watches that will serve you well. Worried about scuffs and scratches? Take a look at the Instinct line; they’re built like tanks and have incredible battery life.If you're seriously into your training and want the most profound insights into your health and fitness, the Fenix 8, Epix Gen 2 and their newer Pro variations are excellent choices. The Fenix 8 is perfect if you want to explore new routes, as its high-res OLED display is brilliant for mapping.What’s the best beginner Garmin running watch?Beginners just starting their running journey are likely going to run shorter distances without worrying about complex running metrics. They'll also want to make a smaller investment, buying a cheaper running watch.We recommend the Garmin Forerunner 165 for under AU$400, thanks to its reliable GPS tracking, heart-rate monitoring and easy-to-understand pace, distance and training data. If you’re on a budget, the Forerunner 55 is a solid choice — in fact, some top-tier pros still choose it! Garmin’s other watches are also excellent options, but they're packed with features that many beginner runners might not need at first, such as full-colour maps, recovery insights and training plans.
