Several of the most-viewed posts on this site are about the Apple Watch and Garmin so I know people enjoy reading about these comparisons! Once I get the new Apple Watch Series 4, I will be doing real comparisons to a couple of similar Garmin watches. But, with preorders starting in less than 12 hours, I wanted to lay out the spec comparisons between the new Apple Watch Series 4 and the closest Garmin product.
Stacking Them Up: New Apple Watch Series 4 vs Garmin
With the new Apple Watch Series 4 starting at $399, it places it pretty much in direct competition to the Garmin Forerunner 645. For more direct comparison, we will use the $449 Garmin Forerunner 645 Music.
To keep it fairly even, I am using the 44mm Apple Watch Series 4 GPS ($429) and the Garmin Forerunner 645 Music ($449). Note that both manufacturers use fancy language to describe the glass face which is really different kinds of strengthened glass. Neither watch uses a Sapphire crystal (you need to move up to the Garmin Fenix 5 Sapphire or the 5 Plus Sapphire for Garmin or the Apple Watch Stainless Steel – both sets are similar prices).
