Garmin designed the Forerunner 645 Music to go with you wherever—or whenever—you run.
The GPS watch has a slim profile, and the 1.2-inch diameter face is large enough to read while on the move without being cumbersome on smaller arms. In dark situations, the watch uses an activity-activated backlight to illuminate the watch face when you tilt your wrist—one Fleet Feet tester loved the touch-free ability to keep track of his time and pace during a nighttime fartlek.
To house the internal hardware, Garmin sourced chemically strengthened glass and rugged stainless steel that give the watch a minimal, modern look, and they made it waterproof so it’s safe to wear while swimming or showering. Designers also fit the timepiece with interchangeable, quick-release Garmin watch bands made of supple and durable silicone. One wearer said the band felt really soft and comfortable against her wrist, and its low profile stayed out of the way.Shop Garmin Forerunner 645 Music
