The S1W combines a high-sensitivity GPS receiver with a lightweight, flexible sport watch. It gives you distance information to the front, back and middle of greens for 17,500 preloaded U.S. and Canadian courses. You can measure individual shot distances, track how far you walk on the course, and then use the alarm to get you up in the morning. Approach S1W is golf's first full-featured sports watch and golf GPS in one.
