Work centers on diagnosing why a watch, clock, or chronometer is running fast, slow, or not at all, disassembling the mechanism, cleaning and lubricating parts with solvents and oil, then replacing worn components and reassembling and testing the timepiece for accuracy under a loupe. Because the occupation is shrinking as digital and mass-produced timepieces reduce demand for hands-on adjustment, most remaining jobs are concentrated in specialty repair shops, jewelers, or manufacturers of high-end mechanical watches.
Pros
Standard, predictable full-time hours in a climate-controlled indoor setting
Meticulous hands-on craft work using precision tools like loupes and watchmakers' tools
Entry possible with just a high school diploma and on-the-job training
Cons
Employment is projected to shrink sharply over the next decade (-17.5%)
Entry-level pay can be quite low before skills are built up
An already tiny, shrinking occupation with very few positions nationwide
A typical day
The bench is spotless by necessity: today's work is movement assembly, setting wheels and pinions into plates under magnification where a speck of dust is a mechanical fault. The morning's rhythm is tweezers and screwdrivers sized like toothpicks, each screw seated with exactly enough torque and no more. After lunch comes adjustment -- timing machines listen to each movement's beat, and tiny regulator moves bring a fast watch back toward true. The day ends with quality checks and logging serial numbers, every piece accountable from bench to box.
Tasks at the job
Observe operation of timepiece parts and subassemblies to determine accuracy of movement, and to diagnose causes of defects.
Replace specified parts to repair malfunctioning timepieces, using watchmakers' tools, loupes, and holding fixtures.
Clean and lubricate timepiece parts and assemblies, using solvents, buff sticks, and oil.
Assemble and install components of timepieces to complete mechanisms, using watchmakers' tools and loupes.
Test operation and fit of timepiece parts and subassemblies, using electronic testing equipment, tweezers, watchmakers' tools, and loupes.
Disassemble timepieces such as watches, clocks, and chronometers so that repairs can be made.
Workplace & working conditions
Work happens indoors in a climate-controlled setting.
You're expected to exercise significant independent judgment day to day.
