ONE GARMIN FORERUNNER 955 SOLAR
You’d think the Pixel Watch would be an ideal pairing for a Google phone, but fitness buffs training for long races would be better off with this Garmin. It has much better battery life than most: around 20 days of normal use, and over 40hrs with GPS on. It also offers contactless payments and third-party apps.
