Quartz watches have become popular watches among collectors since their introduction to modern life in the 1970s. Quartz technology uses a crystal to electronically control an oscillator to produce accurate signals that maintain accurate time. This makes quartz watches incredibly reliable and they are also relatively inexpensive to manufacture. Quartz watches are very collectible, even though LED watches have replaced them lately. A worn or damaged quartz watch is simple to repair, and individual components are still widely available.

0.8 mm to 1.0 mm screwdriver
replacement rod
Replacement spring

Perform a visual examination of the quartz watch and look for obvious signs of wear or damage. Check if all hands are operational and the wind of the rod to ensure that it engages properly. The stem must be able to move the time and minutes if it is fully functional. Remember that quartz watches work using a battery so the stem does not have to be hand wound.
Open the back of the quartz watch using the case of a watchmaker's first match or a small precision screwdriver between 0.8 mm and 1.0 mm. Take extreme care when removing the backplate to avoid scratches. Remove the old battery and dispose of it responsibly. Add a replacement battery and check the face of the quartz watch to ensure that the second hand moves.
Leave the backplate off and look to the inside left side of the watch mechanism to locate the rod. Take a small screwdriver from your professional watch repair kit and use it to gently push down on the spring to release the rod mechanism and remove it completely. Insert the new rod and spring into position and push in firmly. Make sure the new strain is able to move on time and minutes when pulled into an extended position.
Take a bottle of compressed air and lightly blow inside the quartz watch to remove any dust or debris. Place the plate in position and secure by snapping it into place or reinserting the removed screws.
Finish repairing the quartz watch by removing the strap pins with the help of the small precision screwdriver for watch. Discard the old strap and place the strap markers in each end of the new strap. Attach the new strap to the body of the watch, using the small screwdriver to manipulate the pins in the correct position. The quartz watch should now work and is ready to wear.
