Connect and Customize
Smart notifications4, automatic uploads4 to Garmin Connect and live tracking make 735XT the ultimate smartwatch for athletes. Keep your phone tucked away when you’re on a long ride or run, and get all your notifications at the wrist so you can decide to respond or keep moving.

Your friends and family can view and comment, no matter how far away they are.

LiveTrack lets family and friends track your location in real-time while you’re riding, and now it’s even easier to use. When you enable auto-start, you can spend more time focusing on the ride and less on the technology. LiveTrack will automatically detect when you start riding, which means there’s no need to even reach for your phone anymore. Auto-start is also compatible with the new Strava Beacon, which lets Strava Premium subscribers take advantage of the same great feature. It’s never been easier for you and your loved ones to have peace of mind while you ride.
