Most exposed

Where AI can do more

Routine, digitized, and highly repeatable tasks face the greatest pressure.

  1. Adjust sizes or positioning of timepiece parts to achieve specified fit or function, using calipers, fixtures, and loupes.81
  2. Change timing weights on balance wheels to correct deficient timing.81
  3. Mount hairsprings and balance wheel assemblies between jaws of truing calipers.81
  4. Bend parts, such as hairsprings, pallets, barrel covers, and bridges, to correct deficiencies in truing or endshake, using tweezers.81
Hardest to automate

Where people still matter

These tasks score lowest on automation feasibility—physical presence, judgement, accountability and real-world variability all resist end-to-end automation.

Beyond AI capability

Adoption and labour-market outlook

Structural factors are kept separate from raw capability so you can see what actually resists automation. Adoption pressure and labour-market resilience are still provisional models—25% of this occupation’s replacement-risk weight rests on them.
