The Approach S20 GPS golf watch is the ideal golfing partner that doubles as your everyday watch. Stylish, convenient and lightweight, Approach S20 comes preloaded with more than 41,000 courses from around the world. Map updates are automatic. And the bundled 3-pack of Approach CT10 club trackers pair with your watch to augment AutoShot performance while adding automatic game tracking of your score and shot stats for any club.
See Before You Swing
Whether you’re leisurely playing with friends on your favorite local course or teeing up on that amazing resort course you’ve always wanted to play, Approach S20 knows where you are — and how far you are from the next pin. The watch’s high-sensitivity GPS receiver gives you the distance data you need to fire away with confidence. On the high-resolution display, you’ll see distances to the front, back and middle of the green as well as hazards, doglegs and layups. You can also measure yardages for shots played from anywhere on the course.
AutoShot Round Analyzer
On the Garmin Golf app, your Approach S20 golf watch’s AutoShot round analyzer tracks shots, measures distance and records shot locations for post-round analysis on Garmin Connect, our free online community.
Know Your Clubs
Pair your Approach S20 watch with the bundled 3-pack of Approach CT10 club sensors for automatic game tracking and scorekeeping. The lightweight and secure sensors easily attach to the end of a club’s grip; you won’t even notice them while you play. You can order additional sensors to track all 14 clubs in your bag. Or you can stick with the included 3-sensor pack for your wedges and putter to track chip shots next to the green and your putts — while relying on your golf watch’s AutoShot analyzer to track and record your other shots.
Garmin Golf App
Use the free Garmin Golf app on your compatible smartphone paired with your Approach S20 watch to improve your game with additional features.
You can track and analyze your stats for each club to see what parts of your game need work. Your golf watch automatically keeps track of your score throughout your round. Then, the mobile app lets you upload your scorecard to participate in weekly online leaderboards and tournaments. You can also live chat with other players in the Garmin Connect golf community to compare data, rankings and stats for bragging rights at the 19th hole.
Green View Display
The Green View feature on your Approach S20 shows you the true shape and layout of the green, even if you’re behind it. You can manually reposition the pin to today’s location for accurate shot selection.
Smartphone Notifications
Never miss another important text, email or alert just because your smartphone is tucked away somewhere in your bag. Approach S20 acts as a wireless extension of your compatible smart device, displaying smart notifications right on your watch¹. Now, via Bluetooth® technology, you can read that email or text you’ve been waiting for — even in the middle of the fairway.
Extra-long Battery Life
Your Approach S20 features a long-running lithium-ion battery to carry you through long rounds or those extra holes. You can easily get in a whole weekend of golf with up to 15 hours in full GPS mode before the battery needs to be recharged. For daily use in activity tracking mode, you can expect the battery to go up to 8 weeks between recharges.
It’s All the Watch You Need
As a bonus, the handsomely styled Approach S20 golf watch even tells you the time, so you can wear it as your everyday watch. Durable and water-rated to 5 ATM (50 meters), Approach S20 also features a built-in activity tracker with prompts to help keep you moving toward a healthier lifestyle. And for those who like to walk, there’s a built-in odometer to help keep track of how much ground you’ve covered.
