The Prime Day sale is still a few days away, but Amazon has already served us smartwatch deals that are too good to be missed. This one, for example, could be a gold find for budget-conscious runners or busy gym-goers: the Garmin Forerunner 255 has just been discounted by a massive $150, bringing it to its lowest-ever price. If you are not a fan of Amazon, you can also find the same deal at Best Buy.

This fitness tracker may not have the military-grade durability and long battery life of some of the best Garmin watches, but it does get all the basics right: it is light, comfortable to wear all day and very beginner-friendly, but at the same time, it does not skimp on advanced features or tracking accuracy. We gave the Garmin Forerunner 255 a strong four-star rating in our full review, so we can confidently attest that this smartwatch offers great value for money. For less than $200, this early Prime Day deal is not to be missed.

Save 43% on the 46 mm Garmin Forerunner 255 in slate gray and blue. This running watch offers up to two weeks of battery life, advanced workout tracking features and reliable GPS navigation, all delivered in a sleek, stylish package. A perfect all-rounder for budget-conscious runners.

Editor's note 08/07/2025: The Garmin Forerunner 255 has sold out at Amazon, but this online retailer still offers the Garmin Forerunner 255 Music at its lowest-ever price, so snap this deal up while it lasts!

We particularly liked its always-on display. The Garmin Forerunner 255 delivers great visibility in both dim and bright conditions. Its transflective MIP screen may not be as fancy as an AMOLED touchscreen, but this has its benefits. For example, it is less battery-zapping. Speaking of battery life, the Garmin Forerunner 255 can last up to 14 days, which is almost twice as much as what you can see in other fitness trackers in this price range. For less than $200, this smartwatch is a steal.
