I have the Garmin S1 watch and absolutely love it. It is very accurate and provides me with the information which I reallly need at a glance. Battery life is good and it is simple to recharge. On arriving at course all I have to do is push a button and it finds the course I am on. In addition to telling you distances to front, middle and back of the green, it can also measure distance of shots. The overiding feature for me is the abilility to look at your wrist and get the distance information you need. I did not wear a watch before purchasing the S1, but have had no trouble getting use to it. The watch is relatively light and comfortable.
