Marking Laps Using the Auto Lap Feature
You can set your watch to use the Auto Lap® feature to mark a lap at a specific distance automatically. This feature is helpful for comparing your performance over different parts of an activity (for example, every 1 mile or 5 kilometers).
Each time you complete a lap, a message appears that displays the time for that lap. The watch also vibrates if vibration is turned on (System Settings).
