How do you control dimensional tolerances in case manufacturing?

2026-07-03
We follow ISO standard tolerances for watch case manufacturing. Critical dimensions — including movement fitting, crystal fitting, and crown tube alignment — are held to ±0.05mm (about half the thickness of a human hair). We set up 100% inspection checkpoints after CNC finishing — every case goes through CMM (Coordinate Measuring Machine) verification, and out-of-tolerance parts do not move to the next stage.
