Very timely, I just posted my experience with using a smartwatch and the available apps. I just started using my Samsung Galaxy smartwatch and really like the simplicity of it. My golfing partner was constantly asking what the distance to the pin was. I found it very accurate and will continue to use it as my regular watch and on the golf course.
Before the smartwatch, I did wear a watch while golfing. Feel naked without a watch on.
If I wear my watch while swinging it rubs a raw spot on the underside of my right forearm basically midway about 1/3 of the way from my wrist to my elbow. I guess my release runs that part of my across the clasp of my watch on my left wrist. For this reason I take it off, otherwise I would wear it.
