The asking price has consistently hovered around $800 since Garmin launched the battery life powerhouse in 2021.
With this flash sale from Amazon, though, the Enduro is now available for $459.99 - a huge dip from last week's price of $765.
The previous all-time low offered by the retailer occurred back in December, though even this saving only trimmed the asking price down to $674.99.
It brings the overall saving available for the Enduro to just over $300 - and gives anybody previously put off by the previously lofty tag a superb opportunity to grab one of the market's most rounded and long-lasting trackers.
When we reviewed it back in 2021, we said: "It’s a comprehensive all-rounder built for endurance, and, with reliable GPS, solid heart rate performance and an impressive suite of training, racing, recovery and health tracking, it’s equally good as your regular training partner."
And while it does miss out on the mapping and music support available in the newer Enduro 2, you still get much of the core experience in the original model - and, with this deal, at the cost of a mid-range Garmin Forerunner model, such as the Forerunner 265.
As ever, it's not clear how long Amazon will extend this saving for - or, indeed, how long stocks will last - so be sure to snap this one up sooner rather than later to avoid disappointment.
