In the 1920s, Adi Dassler hired two shoemakers to create the first shoes designed for athletes. By 1927, his first shoe was patented in Germany. After WWII, the company contracted with the American Army to produce ice hockey shoes with canvas tops scavenged from U.S. Army tents. By the 1960s, adidas expanded into other sports equipment such as clothing, balls and watches. Today, adidas watches are designed to help athletes track their performance times and heart rate. Because of their delicate nature, anything more complex than changing a battery or watchband should be done by a professional.
Find the watch band bracket. The watch band is held in place with the spring bar. The spring bar goes through a slot in the watch band and presses against two lugs on either side of the bracket.
Slip the spring bar tool between the watch band and the bracket. Push inward and the spring bar will compress and pop out of the lugs.
Clean the watch band bracket with a soft cloth.
Place the spring bar in the slot of the new watch band. Some new watch bands are packaged with a spring bar already in place.
Place one end of the new spring bar in a lug on one side of the bracket. Slide the other end of the spring bar behind the second lug. Gently pull the watch band forward until the spring bar slips into the second lug.
Look at the edge of the watch case. There is a groove going all the way around the watch case. This is where the front of the watch and the back come together. There will be a notch on one part of the groove.
Spread the cloth on a firm surface. Lay the watch face down on the cloth.
Slide the spring bar tool into the notch. Press on the tool to pry the back away from the case.
Remove the battery from the back of the watch. Take the battery to a jewellery or battery store. Test the battery and, if necessary, purchase a replacement.
Place the battery in the appropriate slot. Lay the back on the watch and gently push with two fingers until the case snaps closed.
Do not open watches that are closed with screws or that are labelled as waterproof. These watches are sealed with gaskets that are easily damaged. Opening these watches will void the warranty.
