The Garmin Fenix 8 Pro is a luxury smartwatch with rugged features. ZDNET readers can't get enough of it on the first day of Prime Day.

The Garmin epix Pro Gen 2 Sapphire Edition launched at $1,099 and just landed at exactly half that price for early Prime Day, at nearly zero margin for Amazon.

Many of Garmin's signature smartwatches are on sale for Prime Day, including Forerunner, Fenix, and Venu models.
