Watch repairers test, adjust, repair, and clean watches, clocks, and other timepieces.

Watch repairers talk to customers about the watch or clock's problem and its service history. They estimate how much it will cost to fix the piece.

Repairers take apart timepieces and look for dirt, rust, or worn parts. They clean parts using special solutions or ultrasonic cleaning machines. Watch repairers replace worn or broken parts with new parts.

After repairs, watchmakers check the accuracy of timepieces, using timing machines. They use a special machine to demagnetize watch parts and cases which can increase accuracy. Watch repairers also use other specialized tools, such as:

• Tweezers
• Pin vises
• Micro-lathes
• Files

Watch repairers who work on electric and electronic timepieces replace batteries and clean and replace parts. They use meters and other electronic instruments to test timepieces for correct performance.

Watch repairers who work in jewelry stores may also clean and repair jewelry. They sometimes sell clocks, watches, jewelry, or silverware.

Self-employed watch repairers order supplies, parts, and merchandise. They plan advertising, keep books, and supervise employees.
