UR-111C Iron

In the URWERK tradition, none of the indications of the UR-111C watch are conventional. Never has a roller on the case performed the functions of the crown, nor have the running seconds meandered across a cluster of optical fibers. Nor would it be an authentic URWERK watch if its case didn’t look as if it had been designed by a Sci-fi passionate.

Digital seconds appear alternately, transported into visual range by a dense cluster of precisely aligned optical fibers. A world Première in the watchmaking area!

The UR-111C’s digital seconds are mounted alternately on two tiny wheels. Each openwork seconds wheel weighs 0.018 grams (0.025g with numerals) — miniature lacework in metal thanks to the LIGA process. Converting the horizontal movement to a vertical time display required precisely angled transmission with miniature bevel gears. The minute cylinder rotates 300 degrees to bring the helix to the 60th minute, at the same time arming a long, coiled spring. To bring the helix back to the start, the spring releases to snap the cylinder forward.

Instead of the conventional crown at the end of the stem, URWERK conceived a roller integrated into the top of the case above and parallel to the winding stem. Bevel gears for 90° transmission – driving the cones and minute cylinder. Instead of pulling out a crown you swing out a lever from the side of the case.
