Finally a high performance Golf GPS watch that's stylish enough to wear on and off the course! Preloaded with over 30,000 worldwide courses, the Callaway GPS Sync Watch blends elite on-course performance with an elegant, fashionable design. Shoot lower scores by hitting more greens and avoiding penalty strokes - by knowing precise distances to the front, center and back of the green, as well as layup and carry distances to hazards and doglegs. Synchronize with your smartphone to enable text, email and missed call notifications, and upload round scores and stats. Includes auto-hole advance, shot distance measurement and odometer. Rechargeable lithium-ion battery lasts 2-3 rounds in GPS mode on a full charge, and 90+ days in time mode (only).
