For Prime Day Amazon is offering a whopping 43% discount on the Forerunner 255, bringing its price down to just $199 from its regular price of $349. This is the company’s best-selling product, and it has a 4.7 out of 5 rating and it can be purchased as a limited time offer that does not require a Prime membership.

Garmin has slashed prices across its entire wearable range, but the standout offer by far is the Forerunner 255. Right now, you can grab it for just £199 – down from £349. That’s 43% off one of Garmin’s most beloved GPS watches.

The question is how old is too old with regards to buying a Garmin watch. The Garmin Forerunner 255 is just $199 at Amazon right now, matching its lowest ever price, but it's three-years-old now and has been superseded by two newer models.
