Garmin launches its first GPS watch to store music, Forerunner 645, with 3.5GB storage that can save ~500 songs, starting at $449
Ready to hold 500 songs from iHeartRadio, iTunes, and other playlists. … Garmin's Vivoactive 3 provided a solid alternative to the Fitbit Ionic …
Context & Ripple Effects
Garmin has been climbing the wearable price ladder all decade: the Forerunner 25 added GPS and smartphone alerts at $170 in 2015, and last August's $299 Vivoactive 3 brought Garmin Pay and sport profiles as a credible alternative to Fitbit's Ionic. What none of those watches could do was hold music — runners still needed their phones.
The Forerunner 645 changes that: it is Garmin's first GPS watch with onboard storage, 3.5GB for roughly 500 songs pulled from iHeartRadio, iTunes, and other playlists, priced at $449. That puts phone-free running — the headline feature of pricier full smartwatches — into Garmin's dedicated sports line.
First-order effects
- Runners who buy the 645 can leave the phone at home, closing the single biggest functional gap between Garmin's sports watches and music-capable rivals like the Fitbit Ionic.
Second-order effects
- The feature cascades down the line fast: five months later Garmin ships the Vivoactive 3 Music with the same ~500-song capacity at $299, undercutting the 645 and forcing buyers to weigh sports features against price rather than music alone.
Third-order effects
- If every new Garmin tier ships with storage, the product line stops being a set of phone accessories and becomes standalone devices — with battery life, not app ecosystems, as the differentiator against general-purpose smartwatches.
The trend: Fitness wearables are absorbing smartphone functions one feature at a time — payments, then music — turning GPS sports watches into standalone devices while keeping multi-day battery life as their edge.
