🔧 What it does & how to use

This press is used by watchmakers and hobbyists to fit replacement crystals into watch cases and to close snap-on case backs securely, without marking the case or crystal. The set of six nylon dies lets you match the die to the diameter of the crystal or case back being worked on.

• Select a die: Choose the nylon die that best matches the diameter of the crystal or case back.
• Position the work: Stand the press upright on a flat, stable surface and place the case or crystal centrally on the base die.
• Apply the press: Bring the top die down and apply firm, even pressure to seat the crystal or close the case back.
• Check the fit: Confirm the crystal or back sits flush before releasing pressure and removing the piece.
