  • Bend inner coils of springs away from or toward collets, using tweezers, to locate centers of collets in centers of springs, and to correct errors resulting from faulty colleting of coils.
  • 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.
  • Estimate spaces between collets and first inner coils to determine if spaces are within acceptable limits.
