How to Repair a Polar Running Watch

Replacing a Broken Watch Band

• 1

  Locate the watch band brackets on either side of the watch. Holding the watch band in place are the spring bars. These tiny spring-loaded bars are seated in lugs on either side of the watch band bracket.

• 2

  Insert the spring bar tool into the side of the watch band bracket. The spring bar tool is a thin piece of metal that can usually be purchased at a craft or jewelry supply shop.

• 3

  Press the spring bar tool toward the center of the watch band bracket. This will depress the spring bar and the watch band will come out of the watch band bracket.

• 4

  Put the spring bar into the new watch band. Some watch bands will already have a spring bar installed at the time of purchase.

• 5

  Carefully put one end of the spring bar into the lug on the side of the watch band bracket. Slide the other end of the spring bar at an angle behind the second lug on the other side. Gently pull the watch band forward until the spring bar pops into the second lug.
