    Verdict

    The Garmin Approach S42 is a mid-range golf smartwatch featuring a 1.2-inch sunlight-readable colour touchscreen (240 x 240 resolution) housed in a lightweight 43g metal bezel design. Key characteristics include GPS tracking for over 42,000 preloaded global courses, Green View for manual pin positioning, and AutoShot detection to record shot distances. It offers a solid battery life of up to 15 hours in GPS mode and 10 days in smartwatch mode, alongside daily activity tracking for steps and sleep and a 5 ATM water rating. Pros include its stylish design suitable for off-course wear, highly accurate yardage, and a responsive interface that pairs seamlessly with the Garmin Golf app for performance analysis. However, notable cons include the lack of a built-in heart rate monitor, the use of a proprietary charging cable, and a display that is less vibrant than modern AMOLED screens.
