How do they match: Timing Device Assemblers and Adjusters

  • Barrel Bridge Assembler

  • Bend parts, such as hairsprings, pallets, barrel covers, and bridges, to correct deficiencies in truing or endshake, using tweezers.
  • Change timing weights on balance wheels to correct deficient timing.
  • Observe operation of timepiece parts and subassemblies to determine accuracy of movement, and to diagnose causes of defects.
  • Test operation and fit of timepiece parts and subassemblies, using electronic testing equipment, tweezers, watchmakers' tools, and loupes.

  • Review blueprints or other instructions to determine operational methods or sequences.
