  • Avoid touching the dial and hands directly to prevent damage or smudging.
  • Use hand levers or hand removers to lift the hands off the dial if necessary.

Be mindful of the fragile balance wheel and hairspring inside the movement; any shock or pressure can impair function.

Removing the Watch Hands

Removing the hands requires precision tools and a steady hand. This allows access to the dial and underlying components.

Key points:

  • Use a hand remover tool designed to lift hands vertically without bending or distorting them.
  • Protect the dial surface with a thin piece of plastic or paper to prevent scratches.
  • Start with the seconds hand (if present), followed by the minute and hour hands.
  • Gently pry the hands upward, ensuring even pressure.

Once removed, store the hands in a safe container to avoid bending or loss.

Detaching the Dial

The dial is typically secured to the movement via screws or dial feet.

Steps to detach:

  • Identify the dial screws, often located on the sides of the movement.
  • Using a precision screwdriver, loosen the screws without fully removing them to avoid dropping them inside the movement.
  • Carefully lift the dial away from the movement, holding it by the edges.
