At my 28th birthday (about seven months ago), my wife gave me a nice gift. It is a kinetic watch. Kinetic watch is a watch that not uses any batteries. It works with vibration only, so the power comes from my hand that keeps moving all the time and from my pulse beat. Actually I dislike wearing any watch because my skin is very sensitive. Redness will appear at my wrist if I wear watch for a long period of time. Because this is a special gift, I always use it. This is my second watch since I was a kid (my mom gave me one when I was at 9). This kinetic watch is made from pure stainless steel, so it cannot become rust. Beside time as the main feature, there are also other indications such as month, day, and date. It is very user friendly. I just push the button to set them. Each buttons represent one function. However, this watch has a disadvantage. When I put it on the table for one night, the next morning I have to re-set the time again. Anyway, I am glad to have this watch. This is the nicest gift I ever had. This product is made by Chopard, a good kinetic watch from Japan. It is only available at original watch shops in Indonesia.
