Special KOCH machines make wires for luxury Swiss watches

The new special straight-line drawing machines that KOCH recently completed are able to manufacture high-strength wires for watch wristband pins. The drawn wires are later incorporated in luxury Swiss timepieces that represent the ultimate in quality.

All wires produced with the KOCH drawing machines comply with exacting standards of strength and surface quality. “These wires are integrated in the metal bracelets of exclusive watches, so they have to be manufactured with extreme precision,” explained Harald Udelhoven, Technical Director at KOCH. To ensure that the wire is drawn very gently from block to block KOCH has fitted out the machine with specially designed capstans with all-ceramic drawing rings. This prevents any surface damage to the wire.


KOCH is one of the world’s leading manufacturers of wire-drawing machines for diverse sectors of industry in the global markets – from construction and automotive to industries with special quality requirements such as medical technology and consumer goods manufacturing.
